INTRODUCTION
The Maryland School Assessment (MSA) is a measure of students’ reading and mathematics comprehension. The MSA fulfills recommendations of the Visionary Panel for Better Schools and meets the federal testing requirements of the No Child Left Behind Act (NCLB) of 2001.
New academic standards were designed to inform parents, teachers, and educators of what students actually learned in schools and to make schools accountable for teaching contents measured by the MSA. To this end, the Maryland State Department of Education (MSDE), in collaboration with hundreds of educators across the state, developed a series of mathematics tests to measure students’ achievement against the new academic standards.
In 2003, the MSA-Math was introduced in grades 3, 5, and 8; grades 4, 6, and 7 were added to the program in 2004.
The purpose of the 2011 MSA-Math Technical Report is to provide users and other interested parties with a general overview and statistical analysis results of the MSA-Math.
The 2011 Technical Report is composed of four sections and four appendices.
The first section contains the following information:
General overview and purposes of the MSA-Math
Development and review of the MSA-Math items and test
Test form design, test form specifications, item type, and item roles
Operational form construction using the Rasch model
Test administration
Scoring procedures
Operational item analyses
Linking, equating, and scaling procedures
Score interpretation
Test validity and unidimensionality analyses
Field test analysis and item bank construction
Quality assurance
The second section provides the current year’s academic achievement results for grades 3 through 8. It contains information about the cutoff score and pass rate at each performance level for the 2011 math assessment. In addition, students’ performance levels were analyzed by key student subgroups such as gender, ethnicity, and LEA (Local Education Agency).
In the third section, we summarized detailed statistical procedures used for the 2011 math test. This section provides psychometric information in detail to those who might be interested in learning psychometric characteristics and procedures applied in the MSA-Math.
The last section contains statistical results of the 2011 MSA-Math. It includes descriptive statistics for the 2011 math test based on raw scores and scale scores, accuracy and consistency

of the 2011 math test, rater agreement rates, correlation coefficients among substrands, and total and substrand RS/SS conversion tables. Accordingly, this section provides the statistical and psychometric characteristics of the 2011 MSA-Math.
Four appendices provide additional statistical results for the 2011 MSA-Math: Appendix A contains stratified random sampling results; Appendix B contains 2011 MSA-Math scale score histograms and Tukey charts; Appendix C contains both classical and Rasch (one-parameter logistic item response theory) item parameters. Appendix D contains test blueprints for grades 3 through 8.

1. OVERVIEW OF THE 2011 MARYLAND SCHOOL ASSESSMENT-MATHEMATICS
In 2002, the Maryland State Department of Education (MSDE), in order to conform to the requirements of the new Federal program “No Child Left Behind,” retired its award-winning Maryland School Performance Assessment Program and adopted a testing program known as the Maryland School Assessment (MSA). The new program, like its predecessor, was based on the State Curriculum, which set reasonable academic standards for what teachers were expected to teach and for what students were expected to learn in schools.
In 2003, the MSA-Math was introduced in grades 3, 5, and 8, with grades 4, 6, and 7 being added to the program in 2004. A Bookmark standard setting was conducted in 2003 to set proficiency level cut scores for grades 3, 5, and 8. Because 2004 was the first testing year for grades 4, 6, and 7, a second Bookmark standard setting was held in summer 2004 to set cut scores for these additional grades. The performance level cut scores were used to assign students to three proficiency levels (Basic, Proficient, and Advanced) for AYP reporting under the “No Child Left Behind” act. Information about the Bookmark procedures and results can be obtained from MSDE. The same cut scores have been applied since 2003 (grades 3, 5, and 8) and 2004 (grades 4, 6, and 7).
It should be noted that in 2007, the MSA-Math was administered using a new vendor and applying a different IRT method (e.g., the Rasch model); therefore, a transformation of scale scores using the equipercentile method was conducted with the 2006 population data. Detailed information on the scale score transformation and its results can be found in Appendix C, Year 2006 MSA-Math Recalibration Results from 3-PL IRT to the Rasch Model Using the Equipercentile Method in the 2007 MSA-Math Technical Report.
In 2007, MSDE implemented an important action plan on the MSA-Math test: dropping all of the Stanford Achievement Test Series, Tenth Edition (Stanford 10) items from the 2008 assessment. Consequently, several Stanford 10 items which contributed to the 2007 criterion-referenced test (CRT) were replaced by Maryland-specific items in 2008.
For the purposes of year-to-year linking and equating, we first constructed a 2011 linking pool; only operational selected-response (SR) items (i.e., multiple-choice items) were selected in the linking pool. It should be noted that these SR items appeared both in current and previous years’ assessments and were used as either core or core link items in previous years’ assessments (i.e., in any assessment before 2011). After setting up the linking pool, we conducted a stability check of linking items and decided which items should be excluded from or which items should remain in the linking pool. During the calibration and equating processes, we kept the original operational Rasch item difficulty parameters of any linking items that remained through the stability check to put the 2011 assessment on a common scale. Accordingly, scale scores of the 2011 assessment were linked back to the 2006 assessment and all the scale scores of different years were comparable within each content and grade.
1.1 Purposes/Uses of the 2011 MSA-Math
By measuring students’ achievement against the new academic standards, the 2011 MSA-Math fulfills two main purposes. First, the MSA-Math was designed to inform parents, teachers, and educators of what students actually learned in schools by providing specific feedback that can be

used to improve the quality of schools, classrooms, and individualized instructional programs and to model effective assessment approaches that can be used in classrooms. Second, the MSA-Math serves as an accountability tool to measure performance levels of individual students, schools, and districts against the new academic standards.
1.2 The State Curriculum
Federal law requires that states align their tests with their state content standards. MSDE worked carefully and rigorously to construct new tests to provide a strong alignment as defined by the U.S. Department of Education.
The State Curriculum (SC), which defined what students should know and be able to do at each grade level, helped schools understand the standards more clearly, and included more specificity with indicators and objectives. The format of the SC specified standards statements, indicators, and objectives. Standards are broad, measurable statements of what students should know and be able to do. Indicators and objectives provide more specific content knowledge and skills that are unique at each grade level.
The objectives assessed by the MSA at each grade level are embedded in the SC. In addition, they are identified with the notation assessment limit. Assessment limits provide clarification about the specific skills and content that students are expected to have learned for each assessed objective. Even though some objectives in the SC may not have an assessment limit at a given grade-level, these non-assessed objectives still must be included in instruction. They introduce important concepts in preparation for assessed skills and content at subsequent grade levels.
The following provides one example of assessment limit of Grade 3 MSA-Math:
STANDARD 1.0
Knowledge of Algebra, Patterns, and Functions
TOPIC:
A. PATTERNS AND FUNCTIONS
INDICATOR:
1. Identify, describe, extend, and create numeric patterns and functions
OBJECTIVES:
a. Represent and analyze numeric patterns using skip counting
Assessment limits:
Use 2, 5, 10, or 100 starting with any whole number (0 – 1000)
It should be noted that it was not the case that every indicator would necessarily be tested each year even if 100% of the standards should be tested. Consequently, the SC specified curricular indicators and objectives that contributed directly to measuring content standards, which were aligned to the MSA. More information on assessment limits and standards can be found in Appendix D, The 2011 MSA-Math Blueprint.

1.3 Development and Review of the 2011 MSA-Math Items and Test
As seen in Table 1.1, the development of the 2011 MSA-Math test required the involvement of four groups in addition to MSDE and Pearson. These groups are as follows:
National Psychometric Council
The National Psychometric Council (NPC) took a major role in reviewing and making recommendations to MSDE on the development and implementation of the 2011 MSA-Math program. For example, they made recommendations to MSDE on issues, such as test blueprints, operational form construction, field test design, item analysis, item selection for scoring purposes, linking, equating and scaling issues, and other relevant statistical and psychometric issues.
Content Review Committee
Content Review Committee members ensured that the MSA-Math was appropriately difficult and fair. Committee members were either specialists in math for test items or experts in test construction and measurement. They represented all levels of education as well as the ethnic and social diversity of Maryland students. Committee members were from different areas of the state.
The educators’ understanding of Maryland curriculum and extensive classroom experience made them a valuable source of information. They reviewed test items and forms and took a holistic approach to ensure that tests were fair and balanced across reporting categories.
Bias Review Committee
In addition to the Content Review Committee, a separate Bias Review Committee examined each item on math tests. They looked for indications of bias that would impact the performance of an identifiable group of students. Committee members discussed and, if necessary, rejected items based on gender, ethnic, religious, or geographical bias.
Vision Review Committee
A Vision Review Committee reviewed the items and any associated art for bias to the visually impaired. The committee made their recommendations to exclude from Form A any item they had a concern with since this form is usually used for large print and Braille forms.

1.4 Test Form Design, Specifications, Item Types, and Item Roles
Test Form Design
The MSA-Math test had two forms of operational items at each grade. Field test items were embedded within the operational items resulting in a total of 10 test forms at each grade. As can be seen from Table 1.2, Forms A, B, C, D and E are identical with respect to operational items (designated as operational Form A) and differ only with respect to field test items. This is also true for Forms F, G, H, J, and K (designated as operational Form F).
Table 1.2. The 2011 MSA-Math Test Form Design: Grades 3 through 8
Operational Item Sets Field test Item Sets

Form A X X
Form B X X
Form C X X
Form D X X
Form E X X
Form F X X
Form G X X
Form H X X
Form J X X
Form K X X
Note. Forms A, B, C, D, and E (Form A) are identical, and Forms F, G, H, J, and K (Form F) are identical in terms of operational test items.
Test Form Specifications and Reporting Category
Tables 1.3, 1.4, and 1.5 provide information on the total number of operational items included in each operational test form and how these items were broken down based on each content standard. It should be noted that the test specifications in these tables represent the targeted test design for each grade and show the targeted distribution of each content standard.
Mathematics has a total of seven content standards (Algebra, Geometry, Measurement, Statistics, Probability, Numbers and Computation, and Process). Some standards have been combined for purposes of reporting subscale. Specifically, Geometry and Measurement standards and Statistics and Probability standards were combined to produce a total of five subscale reporting categories. Tables 1.6 through 1.23 provide information on the actual distribution of score points by standard and reporting category. The number of items and score points for each reporting standard were identical across forms within each grade.

Item Types The 2011 MSA-Math included four types of items: selected response (SR), student-produced response (SPR), brief constructed response (BCR), and extended constructed response (ECR).
SR items require students to select a correct answer from several alternatives. For the 2011 MSA-Math, students selected an answer from four options. Each SR item was scored dichotomously (i.e., 0 or 1).
SPR items require students to record their answers on a grid by shading in circles corresponding to the numbers in their answer. For the 2011 MSA-Math, only grade 7 and 8 tests included SPR items. Each SPR item was scored dichotomously.
BCR items require students to provide a short answer using words, numbers, and/or symbols, while ECR items require students to write an answer that consists of more information than is required for a brief constructed response item.
Both BCR and ECR items consist of Step A and Step B. Step A contributes to the content score while Step B contributes to the process score. Each step was considered as an independent item and separately scored;
All BCR and ECR Step A items received a 0-1 score point range from two independent scorers; all BCR Step B items received a 0-2 score point range; all ECR Step B items received a 0-3 score point range from two independent scorers. The score given was the higher of the first and the second Reader’s scores, provided they were adjacent. A resolution reader’s score was used if two non-adjacent initial scores were received. That is, the resolution reader’s score was used in place of both the first and second Reader’s scores. It should be noted that grade 3 and 4 tests did not include ECR items.
The Role of Operational SR Item
Most SR items were used for both form-to-form and year-to-year calibration and linking. As a result, operational SR items fell into one of the following four categories: unique core, common core, unique core linking, and common core linking items. Form-to-form linking was conduced with both the common core and the common core linking items. The form-to-form calibration and linking procedures can be found in section 1.9, Form-to-Form Linking Procedures. More importantly, however, year-to-year linking was conduced with only the core linking items and year-to-year calibration and linking procedures can be found in section 1.9, Year-to-Year Linking Procedures.
While unique core items appeared on either operational form A or F, common core items appeared on both forms. As a result, only the common core items were used for form-to-form linking. Because the core items were not included into the possible 2011 linking pool, on the other hand, item parameters of these items were recalibrated with the 2011 live operational data (i.e., stratified random sample) and then reserved in the 2011 Maryland item bank for the possible use as core linking items in the future. Classical and Rasch analyses on these core items can be found in section 1.8, Validation Check with the 2011 Core Items.
While a few core linking items appeared only on either operational form A or F (i.e., unique core linking), most core linking items (i.e., common core linking) appeared on both operational forms. As a result, the common core linking items appearing on both forms were used for both form-to-
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration

form and year-to-year linking. The unique core linking items were used only for year-to-year linking.
The role of the core linking items was to place the 2011 scale on the 2006 scale. Because these core linking items carried their operational item parameters on the 2006 scale, they were included in the 2011 year-to-year linking pool. Classical analysis on these items can be found in section 1.8, P-Value Check with Year-to-Year Core Linking Items, and calibration, linking and equating procedures on these core linking items can be found in section 1.9, Linking, Equating, and Scaling Procedures of the 2011 MSA-Math.
The Role of Operational SPR, BCR, and ECR Items
SPR, BCR, and ECR items were divided into one of the following two categories: unique core or common core items. Only the common core items appearing on both operational forms were used for form-to-form calibration and linking. Because these items were not included in the 2011 year-to-year linking pool, new Rasch item and step difficulty parameters were estimated with the 2011 live, operational data set (i.e., stratified random sample). These new item and step difficulty parameters were used to produce each student’s theta estimate. More detailed information about how much these items changed across years in terms of classical and Rasch item difficulty can be found in section 1.8, Validation Check with the 2011 Core Items.

1.5 Operational Test Form Construction Using the Rasch Model
The selection of items to be included in the final operational test forms of the 2011 MSA-Math required a careful consideration based on test blueprints, classical item analyses, DIF analyses, and IRT analyses. Specifically, the Rasch model (i.e., one-parameter logistic IRT) played a major role in constructing the 2011 operational forms. First, Pearson suggested the following guidelines:
Do not include items that are too easy or too hard.
Do not include BCR items with score distributions that do not elicit the full range of rubric scores.
Do not include items with DIF classifications “C” for the SR items and “CC” for the BCR items unless they have been deemed acceptable by the external review of content experts.
Finally, do not include items which have Rasch Infit and Outfit mean-squares lower than 0.5 or higher than 1.5. More specific information on Rasch Infit and Outfit mean-squares can be found in the third part of the 2011 technical report, Overview of Statistical Summaries.
A procedure for using IRT methods to build tests that meet any desired set of test specifications was outlined by Lord (1977). The procedure utilizes an item bank with item parameter estimates available for the IRT model of choice, with accompanying information functions. The steps in the procedure suggested by Lord (1977) are as follows:
First, the shape of desired test information needs to be decided. This was termed as the “target information function” by Lord (1977).
Second, specific items need to be selected from the item bank with item information functions that will fill up hard-to-fill areas under the target information function.
Third, the test information function after test items are added needs to be recalculated. Fourth, until the test information function approximates the target information function to
a satisfactory degree, test items need to keep on being selected.
It should be noted that these steps were implemented within a framework defined by the content specification of the test. In addition, math content specialists from MSDE reviewed the final test forms of the 2011 MSA-Math. The following table and figure show an example of the 2011 MSA-Math operational test form construction using the Rasch (i.e., 1-PL IRT) method. Detailed information about constructing operational forms using the Rasch method can be obtained from either MSDE or Pearson.

1.6 Test Administration of the 2011 MSA-Math
The 2011 MSA-Math test was administered to all students in grades 3 through 8 except for students taking the Alt-MSA-Math or the Mod-MSA-Math. Pearson coordinated the test administration procedures with MSDE prior to implementation. This chapter was prepared to provide general information about the 2011 test administration. Detailed information about the 2011 test administration can be obtained from the 2011 Test Administration and Coordination Manual (TACM) and Examiner’s Manual (EM), which are available from either MSDE or Pearson.
Test Materials
All test materials had to be stored in a secure location prior to test administration. The School Test Coordinator (STC) provided test administration training and test materials to the test examiners. The Daily Testing Materials Tracking Record (or an equivalent form designed by the LEA) was used to track the distribution and return of Test Books.
Before testing began, the Test Examiners (TEs) carefully inventoried all test materials given to them, as they were accountable for the return of all secure materials at the end of testing. The TEs checked to ensure they have all the materials they needed for testing.
For the Test Examiner, Pearson provided the following materials:
MSA Examiner’s Manual for grades 3 through 8-Math
Pre-printed labels
For each student, the following materials were provided by Pearson:
Test/Answer Book
Special accommodations testing materials, if necessary
For each student, the following additional materials were provided by school or student:
Two No. 2 pencils with erasers
Blank scratch paper
Classroom Calculator for Day 1 (all grades)
Classroom ruler with both U.S. customary and metric measurements (all grades)
Classroom protractor for grades 5 through 8
Classroom compass for grades 7 and 8 only
Each classroom used for the assessment also needed the following additional materials:
A sign for the door that reads "Testing: Do not Disturb"
A digital clock or a watch, or clock with a second hand
Two test-related Examiner’s Manuals (EMs) were developed for the 2011 MSA: one version for reading and the other for mathematics for use in all grades 3-8. Developed in partnership with MSDE, the EMs contained instructions for preparation and administration of the test. In addition to the EMs, one Test Administration and Coordination Manual (TACM) was developed for use
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
24
by the Local Accountability Coordinators (LAC) and building-level School Test Coordinators (STC). Included in this manual were instructions for preparation of materials for testing, monitoring of testing, and packaging of materials for return to Pearson for scoring. The TACM was distributed and reviewed during a workshop in January for STCs and LACs, with duplicates sent to each school along with its testing materials.
Test Administration Schedule
The primary test window for MSA was established by MSDE (March 7-16, 2011, with make-up testing held March 17-23, 2011). However, each LEA (Local Education Agency) set a specific schedule for administration of the MSA within that window for their district. For a given test, grade, content area, and test format, all testing (with the exception of the make-up administration) had to take place on the same schedule. Each LEA schedule was submitted to MSDE in advance and approved for each district by the state. For example, all Grade 3 MSA-Math must be administered on the same days throughout the LEA. In addition, each content area in each grade was tested on two days during the window. In any given grade, one content area’s primary testing window was completed before beginning the second content area’s primary testing window.
The MSA-Math testing schedule allowed approximately 2 hours and 30 minutes for testing on Day 1 and 1 hour and 45 minutes on Day 2 (including preparation time and breaks).
For the 2011 MSA-Math, the primary testing days were as follows:
Test materials delivered to schools
(Examiner’s Manuals, Test/Answer Books,
and Test Coordinator’s Kits)
February 16-21, 2011
Mathematics Primary Testing Window March 7 – March 16, 2011
Make-up Testing Window March 17 – March 23, 2011
If a student was absent on the testing days, a make-up test was administered on any two consecutive days within the testing window. If a school had an unscheduled closing or delayed opening that prohibited the administration from occurring on the scheduled testing dates, the STCs were consulted by LACs to determine the testing schedule to be followed.
During the administration of the 2011 MSA-Math, MSDE had testing monitors in selected schools observing administration procedures and testing conditions. All monitors had identification cards for security purposes. There was no prior notification of which schools would be monitored, but monitors followed local procedures for reporting to the school’s main office and giving proper notification that an MSDE monitor was in the building.
Student Participation
MSDE calculates actual participation of students who took the test. This means that the schools are held accountable not only for student achievement on MSA or Mod-MSA testing, but also they are accountable to ensure that at least 95% of students participate in testing. Accordingly, schools should do all they can to test all students on MSA, Mod-MSA, or Alt-MSA, as applicable.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
25
All students in grades 3 through 8 had to participate in either the 2011 MSA-Math or, if determined to be eligible by the student’s IEP, the Mod-MSA-Math. The only exception was that students with severe cognitive disabilities were assessed by the Alternate Maryland School Assessment (Alt-MSA) instead of the MSA-Math or Mod-MSA-Math. The criteria that students need in order to be tested in the Alt-MSA program instead of the MSA-Math or Mod-MSA-Math can be viewed in section 5, Appendix A of the TACM.
Participation of English Language Learners (ELLs) in the MSA-Math or the Mod-MSA-Math
There are special rules that apply to the participation of English Language Learners (ELLs) in the MSA-Math and the Mod-MSA-Math, as follows:
For the MSA-Math and Mod-MSA-Math, ELL students must participate in MSA-Math or Mod-MSA-Math regardless of how recently they entered the U.S. educational system. For ELL students in their first year of enrollment in a U.S. school, “participation” in the MSA-Math or the Mod-MSA-Math is defined as allowing the student to attempt the test for at least 20 minutes. If, after 20 minutes, the TE determines in his or her professional judgment that the student does not possess sufficient English fluency to be able to continue testing, the test administration for that student may be concluded at that time.
Accommodations for Assessment
Accommodations for assessment of students with disabilities (i.e., students having an Individualized Education Program or a Section 504 Plan) and students for English Language Learners (ELL) had to be approved and documented according to the procedures and requirements outlined in the document entitled Maryland Accommodations Manual: A Guide to Selecting, Administrating, and Evaluating the Use of Accommodations for Instruction and Assessment (MAM). A copy of the most recent edition of this document is available electronically on the LAC and STC web pages at https://docushare.msde.state.md.us/docushare.
No accommodations could be made for students merely because they were members of an instructional group. Any accommodation had to be based on individual needs and not on a category of disability area, level of instruction, environment, or other group characteristics. Responsibility for confirming the need and appropriateness of an accommodation rested with the LAC and school-based staff involved with each student’s instructional program. A master list of all students and their accommodations had to be maintained by the principal and submitted to the LAC, who provided a copy to MSDE upon request. Please refer to Section 1 of the 2011 TACM for further information regarding testing accommodations.
Large-Print and Braille Test Books and KurzweilTM Test Forms on CD
The MSA-Math was administered to those requiring (1) large-print Student Test/Answer Books or (2) Braille Test Books, or (3) KurzweilTM Test Forms on CD for a verbatim reading accommodation. For large-print Test/Answer Books, Braille Test Books, and KurzweilTM Test Forms on CD, student responses were transcribed into the standard-size Test/Answer Book following testing.
The student’s name, LEA number, and school number were written on the large-print Test/Answer Book for proper transcription into the standard-size Test/Answer Book.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
26
The pre-printed student ID label was affixed to the standard-size Test/Answer Book containing the transcribed responses, and not to the large-print Test/Answer Book or Braille books. The bubbles on the demographic page of the standard-size Test/Answer Book were not filled in if there was a pre-printed student ID label for the student.
A certified Test Examiner (TE) transcribed the student responses into a standard-size Test/Answer Book exactly as given by the student. The standard-size Test/Answer Book with the pre-printed label attached was returned to Pearson with all other Test/Answer Books.
Large-Print Test/Answer Books and Braille Test/Answer Books containing the original student responses prior to transcription are to be returned with Non-Scorable materials. Any Test/Answer Books which were used as source documents for transcription were invalidated by drawing a large slash across the student demographic page with a black permanent marker.
Once the student responses had been transcribed, the transcribed Test/Answer Book was returned for scoring with the standard-size materials. Specific packing instructions are provided in the 2011 TACM in sections 2 and 3.
Verbatim Reading Accommodation and KurzweilTM Test Form on CD
Students who had a verbatim reading accommodation documented in their Individual Education Plan (IEP), ELL Plan, or Section 504 Plan, and who received that accommodation in regular instruction, received the accommodation on the 2011 MSA-Math. The accommodation was provided by a live reader or through technology. Appendix L of the 2011 TACM provided information on verbatim reading instruction. Technology used to provide the verbatim reading accommodation was KurzweilTM reading software. Official, secure electronic copies of the test were ordered through the LAC. MSDE encouraged (but did not require) the use of the KurzweilTM software to ensure uniformity in the delivery of the verbatim reading accommodation throughout the state.
Students using KurzweilTM software had to familiarize themselves with its operation prior to the test administration. When there were technical difficulties with KurzweilTM a certified staff member was used instead. KurzweilTM Test Form CDs were shipped by Pearson. After testing, schools returned the CDs to Pearson with the non-scorable secure materials.
Administration Procedures for Students with IEP, 504 Plan, or ELL Plan Permitting a Dictated Responses or Use of Word Processor
A student whose IEP, 504 Plan, or ELL Plan permitted a dictated response had his/her responses transcribed at the school level by an eligible TE, or by a staff member working under the direct supervision of a certified TE, into the student’s Test/Answer Book with a pre-printed ID label attached.
A student whose IEP, 504 Plan, or ELL plan permitted the use of a word processor had his/her responses transcribed by hand or under the direct supervision of an eligible TE or STC exactly as the student entered his/her responses on the word processor. The student’s responses were always transcribed at the school level into the student’s Test/Answer Book with the pre-printed ID label attached. After the student’s responses had been transcribed, the memory of the word processor was cleared. The original word-processed print-out was returned to Pearson with the non-scorable materials.

Test Format
All grade levels of the MSA-Math used a Test Book format in which students wrote their answers directly in the Test Book. There were 10 forms of MSA-Math. Different test forms were administered to students in each classroom participating in math tests, and each test form was identified by color and form number/letter. All forms of the MSA Test/Answer Books for each grade had the same grade designation and picture on the front cover. The Test/Answer Books were spiraled within a classroom, and each student used a combined Test/Answer Book.
Since the Test/Answer Books were scanned for scoring, students were encouraged not to use highlights in any part of the book. Although students might be accustomed to using highlighters in daily instruction, highlighting in the Test/Answer Book could obliterate information in a student’s book when it was scanned for scoring. As an alternative to highlighting, students were allowed to lightly circle or underline information in test items or perform calculations to help them in responding, as long as markings did not interfere with the bubbled answer choice area and/or the track marks along the outside margins of each page.
Security of Test Materials
The following code of ethics conforms to the Standards for Educational and Psychological Testing developed by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education (Pearson, 2011):
It is breach of professional ethics for school personnel to provide verbal or nonverbal clues or answers, teach items on the test, share writing prompts, coach, hint, or in any way influence a student’s performance during the testing situation. A breach of ethics may result in invalidation of test results and local education agency (LEA) or MSDE disciplinary action. (p. 11)
The Test/Answer Books for the 2011 MSA-Math were confidential and kept secure at all times. Unauthorized use, duplication, or reproduction of any or all portions of the assessment was prohibited, which is reflected by the following statement (Pearson, 2011):
Violation of security can result in prosecution and/or penalties as imposed by the Maryland State Board of Education and/or State Superintendent of Schools in accordance with the COMAR 13A.03.04 and 13A.12.05. (p. 11)
All materials were treated as confidential and placed in locked areas. Secure and non-secure test materials were as follows:
Secure materials: Test/Answer Books (including large-print and Braille), KurzweilTM test forms on CD, and used scratch paper
Non-secure materials: TACM, Examiner’s Manuals, unused pre-printed student ID labels, unused bill of ladings, and unused green/orange shipping labels

1.7 Hand Scoring Procedures of the 2011 MSA-Math
Students’ responses to SR and SPR items were machine-scored, and their responses to BCR and ECR items were individually read and scored by Pearson.
Hand Scoring Staff
The PSC Project Manager (PSC PM), Content Specialist (CS), and Scoring Directors (SD) participated in the rangefinding sessions in Maryland. (Detailed information about rangefinding procedures can be found in the following portion of this section: Development Procedures for Rangefinding.) The SD was responsible for maintaining annotations and meeting minutes from all sessions. These notes were a record of the comments and decisions made by the MSDE personnel and members of the Maryland teacher committee. These notes were utilized by the SD responsible for training the Scoring Supervisors and Scorers for the respective Maryland prompts.
1) Scorer
A graduate of a four-year accredited college or university who had completed the Maryland-specific domain training. The scorers were eligible to score items for which they had been trained and successfully qualified.
2) Scoring Supervisor
A reader who directly monitored the scoring of a team of Scorers and retrained as needed. The reader had successfully completed the PSC Scoring Supervisor training.
3) Scoring Director (SD)
An experienced and knowledgeable PSC team leader who was responsible for selecting a wide variety of student responses for such activities as rangefinding and building training materials. Selected papers were then submitted to MSDE for comment and approval. Scoring Directors remained on the project as rangefinding participants and trainers. Scoring Directors worked with scoring supervisors and the Content Specialist to oversee the scoring of several items. An SD’s main duty during scoring was to rule on validity of questionable papers and to maintain consistency in scoring decisions.
4) Content Specialist (CS)
Experienced content/training personnel who had served as SDs and were selected by the Scoring Resources staff and Project Manager to train and support Scoring Directors for Maryland.
Scorer Recruitment and Qualifications
All Scorers for MSDE had to provide Pearson their résumé and documentation of a four-year college degree. Human Resources made every effort to recruit Scorers with a teaching background and to match Scorers to projects which suited their educational background and previous scoring experience. Regardless of educational background, applicants then participated in a one-day general introductory training workshop presented by a PSC staff member. These workshops allowed Pearson to introduce potential Scorers and Scoring Supervisors to large-scale scoring in general and to the Maryland rubric specifically. The PSC staff member who presented the workshop evaluated potential Supervisors and submitted these evaluations to the PSC Site Manager with his/her recommendations. Those who successfully completed the workshop were
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
29
added to Pearson’s general pool of potential Scorers and Supervisors of MSA Math. This addition to the scoring pool did not qualify these Scorers for scoring the MSDE program.
Scoring Supervisor Selection
The training for new Scoring Supervisors consisted of a two-day course focusing on the duties and responsibilities necessary to successfully manage a team of Scorers. The workshop was led by the PSC Site Manager and Scoring Directors. The instruction included a review of PSC policies and procedures, sessions on use of ePEN and the monitoring reports to track a Scorer’s speed and accuracy, role playing activities which explored various situations that could occur with Scorers during the scoring of a project, and Scorer counseling and retraining guidelines. Upon completion of the workshop, the PSC Site Manager and Scoring Directors in conjunction with the Content Specialist reviewed each participant’s performance, making sure that each had a complete understanding of the Scoring Supervisor role and its responsibilities. Any participant they found who did not perform to their satisfaction was not added to the qualified Supervisor list.
Scoring Supervisor Project Training and Qualification
Project-specific Supervisor training for MSDE was conducted in the days immediately preceding Scorer training. This training began with the SD reading the rubrics aloud and answering any questions the Supervisor might have regarding the rubric. The SD then read each anchor paper aloud to the Supervisors. Each response in the anchor set was thoroughly explained, including the notes and comments of the rangefinding committee. Practice Set 1 was reviewed next. The Supervisors scored the practice set individually in the electronic scoring system (ePEN) as well as recorded their scores on a paper copy of the practice set, and then waited for all Supervisors to complete scoring the set. When everyone had completed scoring the training set, the SD discussed the responses one by one, focusing on why each received that score and not another. The SD reviewed with the group the reason for assigning each score point and discussed each paper in its entirety. The Supervisors were then ready to score Practice Set 2. Practice Set 2 was scored and reviewed exactly as Practice Set 1.
Having thoroughly discussed both practice sets with the group, the SD explained that in order for a participant to qualify as a Scoring Supervisor, it was required that the Supervisor should score at least 90% perfect agreement on Step A and 80% perfect agreement on Step B on two of three qualifying sets or one of two qualifying sets, depending on the number of sets available for each item. The Supervisors scored the first qualifying set individually and recorded their scores in ePEN. As each Supervisor finished scoring, the SD reviewed the qualifying reports before allowing the Supervisor to proceed to the next qualifying set. Each response was reviewed and any questions the Supervisor had were addressed before the Supervisor attempted the next qualifying set. The Supervisor followed the same procedure with Qualifying set 2 (and set 3 if available). Supervisors had to pass one of two or two of three sets (depending on the number of qualifying sets available per item) with 80% agreement for Math Step B and 90% in Math Step A as specified in the qualification rules or they would be released from the MSDE project.
Scoring Supervisor Duties
Scoring Supervisors were responsible for monitoring the training and qualifying of the Scorers assigned to their team. The Supervisors assisted the SD, if requested, during the training of the Scorers. The Supervisor was responsible for monitoring Scorers’ progress through the qualifying sets. The Supervisor was also responsible for monitoring each Scorer’s assignment of scores to
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
30
the responses. Additionally, the Supervisor reviewed the statistical reports with each individual on the team. The Supervisor consulted the SD regarding variations by the team members from the acceptable standards (95% for Math Step A, and 85% for Math Step B). The Supervisor had the initial responsibility to see that the Scorer maintained the set standards through individual retraining. The SD monitored the Supervisor by reviewing team statistics and working one-on-one with the Supervisor.
Scoring Director Selection and Qualification
The candidates for Scoring Director had been recommended by the Content Specialist, PSC Resource Staffing Managers or Site Manager. The recommendations were based upon the evaluations the candidates received as Scorers and Supervisors and were part of their personnel file. The candidates generally had been Supervisors on large-scale projects for multiple teams, and/or they had served as Supervisors on small-scale projects where Supervisors trained their individual teams. They had been evaluated on their ability to train Scorers as well as their ability to monitor the scoring accuracy and consistency of Scorers. These evaluations were submitted in writing at the end of each scoring project by the Site Managers and SDs that had observed the work of the SD candidates.
Scoring Director Project Training
The SDs familiarized themselves with the rubric. Any questions regarding the rubric were addressed by the PSC Content Specialist or MSDE. The next step was for the SD to become familiar with all their items and all training materials and scoring decisions/issues associated with their items prior to Supervisor training.
Scoring Director Duties
The SD’s job was to conduct the training of the Supervisors and Scorers, oversee the actual scoring of the papers, monitor the work of the Supervisor, and act as the decision-maker for situations or questions that may arise during the scoring process. For example, all condition code (foreign language, off-topic, off-mode, etc.) responses were reviewed by the SD, who had to confirm any such decision and ensure consistency of decisions. (Blank condition codes were assigned at the Scorer level and did not require SD confirmation.) Additionally the SD and Supervisor conducted all resolution readings. The resolution score became the reported score.
The SD also reviewed any potential questionable content responses and forwarded those to the Content Specialist to consult with MSDE before processing.
The SD was also responsible for daily statistical review and analysis of all monitoring reports to ensure the quality of the scoring. Review of the data allowed the SD not only to monitor the Scorer but also to provide the Supervisor with additional input. Available data included 1) individual Scorer agreement rates between two independent scorings; 2) score point distributions by Scorer and trend review; 3) prompt statistics for agreement rates and score point distributions; 4) Resolution data; 5) scorer-level and item-level agreement on validity papers pre-scored by MSDE.
Scorer Training Scorer training was conducted either via online training modules approved by MSDE in advance of scoring or via stand-up training led by the SD. For items requiring stand-up training, each SD was responsible for training the items he/she monitored throughout scoring. After sufficient student responses were scored for equating purposes for the first item, the SD reconvened the group and
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
31
trained the second item. Training began with the definition and an overview of holistic scoring. Training continued with a reading and discussion of the generic rubric and item, and then the student responses in the anchor set were read and discussed. In the anchor set the scores had been recorded on the student responses and were arranged in ascending point-scale order. Each annotated anchor response was read aloud and discussed thoroughly. Emphasis was placed on the Scorers’ understanding of how the responses differed from one another in incremental quality, how each response reflected the description of its score point as generalized in the scoring rubric, and how each reflected the MSDE’s standard for application of each score point.
Once Scorers had all their questions answered and the discussion of the anchor set was finished, the Scorers began to assign scores to the first practice set. Each Scorer independently read and scored the responses in the practice set in the electronic scoring system (ePEN). The correct scores were then read to the group when everyone had completed the scoring. In addition, each practice paper was discussed as to reasons for applying each given score. At this point, Scorers interacted with the SD in discussing the characteristics of each response that earned the assigned score point. The same format was followed for each practice set. During this process, the job of the Scorer was to internalize the scoring scale and adjust his or her individual scoring to conform to that scale. Once all practice papers had been scored and fully discussed, Scorers began the qualifying process.
For MSA Math, there were two or three qualifying sets, depending on the particular item. MSDE informed PSC in writing for each specific administration how many qualifying sets were approved and were available to the Scorers. Scorers had to achieve at least 90% perfect agreement on Step A and 80% perfect agreement on Step B on two of three qualifying sets or one of two qualifying sets, depending on the number of sets available for each item.
Scoring Rules for MSA-Math
The following scoring rules were applied to MSA-Math BCR and ECR items:
Math BCR (Brief Constructed Response) items were scored: Step A: 0, 1 with two readings Step B: 0, 1, 2 with two readings
Math ECR (Extended Constructed Response) items were scored: Step A: 0, 1 with two readings Step B: 0,1,2,3 with two readings
Scores given were the higher of the 1st and 2nd Scorer’s scores provided they were adjacent.
For example:
1st Scorer 2nd Scorer Final Score
1 2 2
2 3 3
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
32
A resolution scorer was used if two non-adjacent initial scores were received.
The resolution scorer’s score was used in place of both the 1st and 2nd Scorers’ scores.
For example:
1st Scorer 2nd Scorer Resolution Scorer Final Score
0 2 1 1
0 3 2 2
1 3 3 3
2 0 1 1
3 0 2 2
Inter-Rater Agreement
Pearson’s scoring system generated many kinds of internal monitoring reports that enabled the project leadership to monitor the accuracy and consistency of scoring. These reports were compiled by prompt, listed the entire prompt’s Scorers, and provided the results of their scoring for each day. Information on these reports included the number of responses read by the Scorers during the period, the number and percent of condition code responses, and the number of responses for which there had been a second reading. The number of responses with second readings provided data that allowed for reporting of the number and percent of responses with perfect agreement; the number and percent of responses on which the first Scorer was a point lower than the second Scorer; the number and percent of responses on which the first Scorer was a point higher than the second Scorer (Adjacent); and the number and percent of responses differing by more than one score point (Non-Adjacent). The Scoring Director also reviewed the daily statistical reports to identify individuals or teams who might need retraining in order to provide continuous scoring consistency on the project. MSDE received data summary reports. Statistical summaries of inter-rater reliability can be found in section 3.4, Inter-Rater Reliability.
Scorer Retraining
When a Scorer’s performance fell below acceptable parameters for a project, the Scorer was retrained. Retraining was the process by which the SD or Supervisor utilized a number of methods such as individual tutoring on problem score points, individual review of selected responses, and anchor and rubric review to get a Scorer back on track with the guidelines provided by a specific program. Group retraining was conducted by the SD every Monday (or following any extended break) during the scoring project. In addition, daily retraining occurred as deemed necessary by the MSDE representative and CS.
Backreading
Pearson’s ePEN system allowed Supervisors and/or SDs to conduct backreads as an additional monitoring method. When conducting backreads, the Supervisor or SD received images of student responses and the scores assigned by the Scorer. Responses selected for backreads might be randomly selected or might be targeted backreads (e.g., responses receiving specific scores,
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
33
etc.). These backreads were very useful in tracking specific areas of confusion for a given Scorer or group of Scorers and assisted the Supervisor and SD in knowing just how to direct retraining activities for individual Scorers or teams. The initial backreading percentage was set at 3%. This percentage might be adjusted either higher or lower by the Supervisor based upon the performance of the Scorer.
Development Procedures for Rangefinding
Scoring Directors were selected by the PSC Scoring Resource Manager and Content Specialist to prepare sets of papers for client approval. These experienced SDs were judged by the CS for their ability to recognize and assemble a wide variety of responses. The SD also participated with the clients as a facilitator during the rangefinding session in order to make notes and be prepared to assemble the finished sets to the client’s specifications. For a given math prompt, the SD had the following responsibilities:
1) To know the prompt and the rubric thoroughly 2) To read responses
Looked for responses that seemed to represent the full range of quality as described in the rubric.
Searched all orders for responses, with particular emphasis on the state’s high-performing districts.
Included not only papers that were homogeneous in their level of quality but also papers that differed in quality from variable to variable but which could be given an overall classification of High, Medium, or Low.
Marked High, Medium, and Low papers—marked especially good ones that might potentially receive top scores.
3) To sort copies
Copies were sorted into piles, reflecting the nature of the flag—all potential high papers were together, all potential medium papers were together, etc., with all problem papers grouped together.
For problem or decision papers, duplicates of types of problems were culled. The best example of each problem type was retained; the rest were set aside for possible future use.
4) To develop sets for rangefinding
Decided which particular papers from the sorted piles should go into sets for rangefinding. Each paper selected went into a rangefinding set arranged in performance from low to high performance.
Rangefinding Procedures
The objective of rangefinding sessions was for the team members to arrive at a consensus as to the score of each paper in the proposed training materials. These sessions were attended by Maryland educators, MSDE, and PSC Project Manager, Content Specialists, and Scoring Directors, who selected and prepared all of the papers that would be reviewed. These papers and their corresponding scores formed the basis of selecting final Anchor Sets, Practice Sets, and Qualifying Sets. Discussions among the team members were important, as they revealed what kinds of qualities characterized certain score points. The most difficult aspects involved
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
34
balancing widely discrepant qualities found in the same paper and defining the line between adjacent scores.
Prior to rangefinding, MSDE Scoring staff reviewed all rangefinding items and categorized each item into one of three categories.
1) An item that very closely mirrors a historical item that has been through rangefinding and has been scored by committee,
2) An item that is very similar but not a precise match to an item that has been through rangefinding and has been scored by committee, and
3) A new type of item for 2011 requiring the committee to review and score the item.
During formal rangefinding MSDE shared Category 1 and Category 2 items with the committee to prompt discussion and gain committee agreement as to the correct category for the item. Category 2 items were reclassified to either a Category 1 or a Category 3 item by the committee.
Items the committee agreed were Category 1 items utilized existing business rules for scoring this type of item and were scored by a combination of the following staff: MSDE Scoring staff, MSDE Content staff, Pearson Scoring Directors and Pearson Content Specialists, and at least one individual from the rangefinding committee. MSDE Scoring and MSDE Content reviewed non-agreement scores from the group and determined the final score for the paper.
The procedure for assigning scores to the papers in each set for Category 3 items was as follows:
The item was reviewed by the committee and criteria were discussed for receiving full credit.
Selected “grounding” papers that represented the full range of scores were read aloud and discussed by the rangefinding panel. Reading aloud focused attention on the ideas presented—or what the student had to say—allowing the panel members to divorce themselves from how the paper looked or how well it had been edited.
After each response was read, each panel member independently assigned a score. An overall tentative score was assigned to each response on which there seemed to be consensus. However, all assigned scores at this point, even those on responses for which there were complete agreement, were provisional and subject to change based on later considerations.
All subsequent responses were read and scored by each panel member independently, using the tentative scores on the previous sets as guidelines. After each set had been read, the results were recorded on a consensus sheet and discussed after each committee member had already recorded tentative scoring decisions. There might be frequent reference to previous responses to make sure that decisions on score points were consistent.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
35
This iterative process of reading, charting, and discussing successive responses had three results:
It established scores for papers for which there was virtually unanimous agreement.
It identified papers that were on the line between two adjacent scores, necessitating the clarification of that line.
It contributed to understanding the rationale behind scoring decisions.
During this process, the tentative scores assigned to earlier responses became firm.

1.8 The 2011 MSA-Math Operational Item Analyses
Classical Analysis with Common Items Used for Form-to-Form Linking
As mentioned in section 1.4, two operational forms were randomly distributed to students and linked using common items appearing on both forms (i.e., operational forms A and F). As a result, classical analysis of these common items was conducted to check if the two groups taking different operational forms were equivalent. The following descriptive statistics were calculated based on a raw, number-right score of the common items: mean (M) and standard deviation (SD). The results indicated that the students taking the two operational forms were statistically close across all grades, as seen from Table 1.25.

P-Value Check with Year-to-Year Core Linking Items
As mentioned in section 1.4, different years’ assessments were linked using core linking items. This section was prepared to provide information about how much p-values (i.e., classical item difficulty) of the 2011 core linking items varied from previous years.
First, only SR items were used for the purpose of year-to-year linking. Second, classical analysis (e.g., p-value) on these items was conducted with a statewide population, and item sequence numbers on the tables were assigned based on the 2011 assessment. Finally it should be noted that detailed information about Rasch analysis on these core linking items can be found in section 1.9, Linking, Equating, Scaling Procedures.
As seen in Tables 1.26 through 1.37, we could conclude that most of the 2011 p-values were almost the same or slightly increased compared to those of previous years across all grades.

Validation Check with the 2011 MSA-Math Core Items
As mentioned in section 1.4, operational items fell into one of two categories: core and core linking items. Because the core items were not included into the 2011 year-to-year linking pool, Rasch item and step difficulty parameters of the core items were reestimated with the 2011 stratified random samples during calibration and equating. (Please see section 1.9 and Appendix A for stratified random sampling procedures) As a result, this section was prepared to provide detailed information about how much the core items changed in terms of item difficulty, both classical item p-value and Rasch item difficulty. Detailed information about the roles of the 2011 core and core linking items can be found in section 1.4, Test Form Design, Specifications, Item Type, and Item Roles.
First of all, it should be noted that a smaller number of cases (i.e., about 2,500) in the table indicates that it is a field-test item. P-values of both BCR and ECR items were calculated by dividing the item mean score by the item score range (i.e., score point 2 for BCR and 3 for ECR). The percentage of “Omits” for each CR item was low and indicated that a small number of students did not respond at all. In general, item p-value analysis results indicated that most of the 2011 p-values were almost the same or somewhat increased compared to those in previous years across all grades.
With respect to the Rasch item calibration and equating, it should be noted that we coded “Omit” of each item as “missing” before we ran the data with the Rasch model. In general, the level of the 2011 item difficulties stayed almost the same or became a little lower compared to that of previous years across all grades. It should be noted that all of the Rasch item and step difficulty parameters were on a common scale (i.e., linked to the 2006 assessment).
In conclusion, both p-value and Rasch item difficulty results reflected the same phenomenon, indicating that the level of item difficulty stayed the same or became a little lower.

1.9 Linking, Equating, and Scaling Procedures
For the purpose of year-to-year linking and equating, we constructed a 2011 linking pool that included only operational selected-response (SR) items (i.e., multiple-choice items). These SR items appeared in both current and previous years’ assessments and were used as either core or core link item in previous years’ assessments (i.e., in any assessment before 2011). After setting up the linking pool, we conducted a stability check of linking items and decided which items should be excluded from or which items should remain in the linking pool. During the calibration and equating process, we kept and fixed the original operational Rasch item difficulty parameters of any linking items that remained through the stability check to put the 2011 assessment on a common scale. Accordingly, scale scores of the 2011 assessment were linked back to the 2006 assessment and all the scale scores of different years were comparable within each content and grade. Rasch recalibration was conducted using the 2006 MSA-Math data in 2007 due to the IRT model transition (i.e., from 3-PL to the Rasch). Detailed information on the 2006 Rasch recalibration and results can be obtained in the 2007 MSA-Math technical report.
Stratified Random Sampling Procedures
To select equating samples, a stratified random sampling method was applied to the 2011 state examinee population. To verify that the sample was representative of the statewide examinee population, the distributions of LEA, gender, and ethnicity of the 2011 sample were compared with those of the 2011 population. Appendix A, The 2011 MSA-Math Stratified Random Sampling, provides the results of 2011 sampling. The results indicated that the equating samples were well representative of the statewide examinee population in terms of LEA, gender, and ethnicity.
Robust Z Procedures
After selecting equating samples, each operational form was independently calibrated to estimate Rasch item difficulty of each item. Then Robust z values of all anchor items were calculated using the following calculations (South Carolina Department of Education, 2001):
The mean and standard deviation of the linking pool’s item difficulties for each operational form
The ratio of the standard deviations between operational Form A and Form F
The correlation between operational Form A and F item difficulties
The difference between operational Form A and F for each item in the linking pool
The mean of the differences calculated above
The median of the differences calculated above
The interquartile range of the differences calculated above
The robust z is defined as (the difference between the test form1 and other test form item difficulty minus the median of the differences) / (interquartile range multiplied by 0.74).
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
111
Guidelines for Selecting Form-to-Form or Year-to-Year Linking Items
Once the above calculations were made, the following guidelines were followed in determining form-to-form or year-to-year common items used for Rasch linking and equating:
Conform to the following protocol criteria: A correlation greater than 0.95 and a standard deviation ratio between 0.9 and 1.1. For example, use all the possible linking items as anchors if an original set of linking items meets these two criteria.
Try not to include items with an absolute value of robust z exceeding 1.645.
If one item difficulty on one form of the current year is eliminated from the linking pool, other item difficulties of the other forms should not be included.
Should not eliminate more than 20 percent of the linking pool items.
Figure 1.15 depicts how we applied the anchor stability guidelines into the 2011 MSA-Math equating.
Form-to-Form Linking Procedures
The stability of the common items appearing on both operational forms was verified at each grade level:
Calibrate the two operational test forms separately
Calculate robust z values of Rasch item difficulties for Forms A and F
Correlate Rasch item difficulties between Form A and Form F
Calculate standard deviation ratio between two forms
After examining the robust z values, correlation coefficient, and standard deviation ratio between the two separate calibrations, it was determined that the common item difficulties were consistent across the two forms for all items and could be included as form-to-form linking items in the fixed calibration of the two forms.
Year-to-Year Linking Procedures
The two 2011 operational forms included a set of year-to-year linking common items that appeared on both current and previous operational forms. We utilized the Rasch item fixed equating method for all of the operational items to be placed on a common scale within each grade.
The stability of the linking common items was evaluated using robust z values, correlation coefficients, and standard deviation ratios.
Tables 1.74 through 1.79 include Rasch item difficulties used for calculating robust z values, correlation coefficients, and standard deviations. Figures 1.16 through 1.27 depict item difficulty plots between current and previous years. It should be noted that the item difficulties of the 2011 operational forms were obtained from independent calibration, and those of previous assessments were on a common scale (i.e., linked to the 2006 assessment).

Reporting Scale Scores
In order to facilitate the use and interpretation of the results of the 2011 MSA-Math, the following formula was used to convert each student’s ability or theta to the reporting scale score:
2954.3808398.32 thetaeScorebilityScalReportingA
SEEReportingS 8398.32
where
theta = the Rasch (i.e., 1-PL IRT) ability estimate, and
SE = the conditional standard error of the ability estimate.
The following table contains information about the slopes and intercepts used to generate the 2011 scale scores. The slopes and intercepts were obtained during the 2006 recalibration. These same slopes and intercepts have been used since the 2006 assessment.

1.10 Score Interpretation
To help provide appropriate interpretation of the 2011 MSA-Math test scores, two types of scores were created: 240-650 scale scores, and performance levels and descriptions.
240-650 Scale Scores
As explained in section 1.9, Linking, Equating, and Scaling Procedures, the 2011 scale scores were placed on a common scale (i.e., 2006 assessment) within the same grade and ranged from 240 to 260. As a result, these scale scores have the same meaning and are comparable across different years’ assessments. However, it should be noted that they are not comparable across grade levels.
For scale scores, a higher score simply means a higher performance on math tests. Thus, performance levels and descriptions can give a specific interpretation other than a simple interpretation because they were developed to bring meaning to those scale scores.
Performance Level Descriptors
As previously explained, performance level descriptors provide specific information about students’ performance levels and help interpret the 2011 MSA-Math scale scores. They describe what students at a particular level generally know and can be applicable to all students within each grade level.
Maryland standards are divided into three levels of achievement (www.marylandpublicshools.org):
Advanced is a highly challenging and exemplary level of achievement indicating outstanding accomplishment in meeting the needs of students.
Proficient is a realistic and rigorous level of achievement indicating proficiency in meeting the needs of students.
Basic is a level of achievement indicating that more work is needed to attain proficiency in meeting the needs of students.
Table 2.1 shows a range of scale scores at each performance level; for example, grade 4 math scale scores from 374 to 432 indicate the level of Proficient. Students in this level passed the MSA-Math standard. This level is considered a realistic and rigorous level of achievement. Further information about the 2011 MSA-Math score interpretation can be obtained from MSDE.

1.11 Test Validity of the 2011 MSA-Math
As noted in the Standards for Educational and Psychological Testing (AERA, APA, & NCME, 1999), “validity is the most important consideration in test evaluation.”
Messick (1989) defined validity as follows:
Validity is an integrated evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores or other modes of assessment. (p.5)
This definition implies that test validation is the process of accumulating evidence to support intended use of test scores. Consequently, test validation is a series of ongoing and independent processes that are essential investigations of the appropriate use or interpretation of test scores from a particular measurement procedure (Suen, 1990).
In addition, test validation embraces all of the experimental, statistical, and philosophical means by which hypotheses and scientific theories can be evaluated. This is the reason that validity is now recognized as a unitary concept (Messick, 1989).
To investigate the validity evidence of the 2011 MSA-Math, content-related evidence, item development procedures, differential item functioning (DIF) analysis on gender and ethnicity, and evidence from internal structure were collected.
Content-Related Evidence
Content validity is frequently defined in terms of the sampling adequacy of test items. That is, content validity is the extent to which the items in a test adequately represent the domain of items or the construct of interest (Suen, 1990). Consequently, content validity provides judgmental evidence in support of the domain relevance and representativeness of the content in the test (Messick, 1989).
The 2011 MSA-Math blueprints provide extensive evidence regarding the alignment between the content in the 2011 MSA-Math and the SC. It should be noted that the 2011 MSA-Math operational test forms were built exclusively using a Maryland item bank program which contained both content and statistical information about both operational and field-tested items. Information on the item composition of the operational test forms can be obtained from section 1.4, Test Form Design, Specifications, Item Type, and Item Roles. In addition, the 2011 MSA-Math blueprints are presented in Appendix D.
Item Development
Test development for MSA-Math is ongoing and continuous. Content specialists, teachers from across Maryland, Pearson, and MSDE were greatly involved in developing and reviewing items. Committees such as content review, bias review, and vision review reviewed all of the items, which were finally stored in a Maryland item bank. Specifically, an internal review by MSDE and Pearson staff for content alignment and quality required a great deal of time and energy. More specific information on item (test) development and review can be obtained in section 1.3, Development and Review of the 2011 MSA-Math Items and Test.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
134
Field test items were embedded and administered in one of ten test forms. Once these items were scored, MSDE and Pearson conducted additional item analysis and content review. Any field test items that exhibited statistical results that suggested potential problems were carefully reviewed by both MSDE and Pearson content specialists. A determination was then made as to whether an item should be eliminated, revised, or field-tested again. Information on statistical analyses for field test items can be obtained in section 1.13, Field Test Analyses and Item Bank Construction.
Differential Item Functioning (DIF)
1) Bias Review of Items
A separate Bias Review Committee examined each math item, with looking for indications of bias that could impact the performance of an identifiable group of students. They discussed or rejected items biased on gender, ethnic, religious, or geographical bias.
2) DIF Statistics
For DIF analyses, subgroups were first identified according to either reference or focal groups. For the 2011 MSA-Math, males and whites were assigned to the reference group and females and African-Americans were assigned to the focal group.
While the Mantel-Haenszel procedure was used for SR and SPR items, the standardized mean difference (SMD) and the standard deviation (SD), along with the Mantel statistic, were calculated for BCR and ECR items. All of the items were classified based on Educational Testing Service (ETS) guidelines. All DIF results were kept in the 2011 Maryland item bank. More information on DIF analyses can be obtained in section 3.7, Differential Item Functioning.
Evidence from Internal Structure
The 2011 MSA-Math has five reporting math standards: Algebra, Geometry and Measurement, Statistics and Probability, Numbers and Computations, and Process. Tables 4.3 through 4.8 show the correlations among the math standards.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration

1.12 Unidimensionality Analyses of the 2011 MSA-Math
Measurement implies order and magnitude along a single dimension (Andrich, 1989). Consequently, in the case of scholastic achievement, one-dimensional scale is required to reflect this idea of measurement (Andrich, 1988, 1989). However, unidimensionality cannot be strictly met in a real testing situation because students’ cognitive, personality, and test-taking factors usually have a unique influence on their test performance to some level (Andrich, 1988; Hambleton, Swaminathan, & Rogers, 1991). Consequently, what is required for unidimensionality to be met is an investigation of the presence of a dominant factor that influences test performance. This dominant factor is considered as the ability measured by the test (Andrich, 1988; Hambleton et al., 1991; Ryan, 1983).
To check the unidimensionality of the 2011 MSA-Math, we examined the relative sizes of the eigenvalues associated with a principal component analysis of the item set. First, polychoric correlation coefficients were computed with LISREL 8.5 (Jöreskog & Sörbom, 1993) because they were polytomously scored on math items. Principal component analysis was then applied to produce eigenvalues. The first and the second principal component eigenvalues were compared without rotation. Table 1.81 summarizes the results of the first and second principal component eigenvalues of the 2011 MSA-Math.
A general rule of thumb in exploratory factor analysis suggests that a set of items may represent as many factors as there are eigenvalues greater than 1 in this analysis because there is one unit of information per item and the eigenvalues sum to the total number of items. However, a set of items may have multiple eigenvalues greater than 1 and still be sufficiently unidimensional for analysis with IRT (Loehlin, 1987; Orlando, 2004). As seen from the following table, the first component extracted substantially larger eigenvalues across all grades: the size of the eigenvalue of the first component was over ten times greater than the second eigenvalue for each form at each grade. As a result, we could conclude that the assumption of unidimensionality for the 2011 MSA-Math was met.

1.13 Field Test Analyses and Item Bank Construction
All field test items embedded in operational forms were subjected to rigorous statistical analyses for their properties in order to provide information about which items may be included as operational items in the future. All statistical results concerning field test items were preserved in the 2011 Maryland item bank. The following field test analyses were conducted:
Classical item analyses for SR, SPR, BCR, and ECR items
Differential item functioning (DIF) analyses
IRT analyses
Classical Item Analyses for SR, SPR, BCR, and ECR items
Classical item analyses for SR, SPR, BCR, and ECR items were conducted within each field test form.
SR items were flagged for further scrutiny if:
An item distractor was not selected by any students (i.e., nonfunctional distractor)
An item was selected by a high proportion of high-ability students while being selected by a low proportion of low-ability students (i.e., ambiguous distractor)
An item p-value was less than .20 or greater than .90.
An item point-biserial was less than .10 (i.e., poorly discriminating). If an item point-biserial was close to zero or negative, the item was checked for a miskeyed answer.
SPR items were flagged for further scrutiny if:
An item p-value was less than .20 or greater than .90.
An item point-biserial was less than .10 (i.e., poorly discriminating). If an item point-biserial was close to zero or negative, the item was checked for a miskeyed answer.
BCR and ECR items were flagged for further scrutiny if:
An item did not elicit the full range of rubric scores.
The ratio of mean item score to maximum score (i.e.., adjusted p-value) was less than .20 or greater than .90.
An item-total correlation was less than .10.
All items required a careful decision. For example, an item that was flagged as being difficult (p-value less than .20) and poorly discriminating (point-biserial less than .10) was considered for being dropped as a possible operational item. However, if the item represented important content that had not been extensively taught, a justification could have been made for including it in an operational test form.
Differential Item Functioning Analyses
Analyses of Differential item functioning (DIF) are intended to compare the performance of different subgroups of the population on specific items, when the group have been statistically matched on their tested proficiency.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
138
In present analyses, the gender reference group was males, and the ethnic reference group was Caucasians. The gender focal group was females and the ethic focal group was African-Americans. For each operational form, the student’s total score was used as the matching variable.
Any SR, SPR, BCR, and ECR items that were flagged as showing DIF were subjected to further examination. For each of these items, for example, math experts judged whether the differential difficulty of the item was unfairly related to group membership using the following criteria:
If the differential difficulty of the item is related to group membership, and the difference is deemed unfair, then the item should not be used at all.
If the differential difficulty of the item is related to group membership, but the difference is not deemed unfair, then the item should only be used if there is no other item matching the test blueprint.
It should be noted that DIF analysis results for all the field test items were archived in the 2011 Maryland item bank. Detailed information about the DIF procedures can be found in section 3.7, Differential Item Functioning.
Item Response Theory (IRT) Analyses
To put the 2011 field test items on a common scale (i.e., the 2006 scale), each field test item was freely calibrated after fixing Rasch item and step difficulty parameters of the 2011 operational items that had been already placed on the base scale during the 2011 operational calibration and equating. For example, each unique field test item appearing on one of five math test forms (i.e., A, B, C, D, and E) was independently calibrated after fixing the same operational items appearing across the field test forms with the same Rasch item and step difficulties because these unique field test forms all correspond to the same operational form (i.e., operational form A).
It should be noted that all the Rasch item difficulties, step difficulties, and fit statistics (i.e., Rasch Infit and Outfit indices) of the field test items were archived in the 2011 Maryland item bank. These field test items are eligible to be used as operational items in subsequent years.
Item Bank Construction
The number of test forms constructed each year and the need to replace items that are released to the public necessitates the availability of a large pool of items. The 2011 MSA-Math item bank continues to be maintained by Pearson in the form of computer files and paper copies. This enables the test items to be readily available to both Pearson and MSDE staff for reference, test construction, test book design, and printing.

1.14 Quality Control Procedures
A standard quality procedure at Pearson was to create a test deck for MSA programs. The test deck began when Quality Assurance entered mock data into the enrollment system, which was transferred to the materials requisition system; the order was packaged by our Distribution Center, and shipped to the Quality Assurance department. We then reviewed the packing list against the data entered, the materials algorithms applied, the materials packaged against the packing list, and the actual packaging of the documents. These documents were then used to create a test deck of mock data, along with advance copies of documents that were received from the printer. Advance printer copies were inclusive of documents throughout the print run to assure we were randomly testing printed documents. The Maryland test deck was a comprehensive set of all documents that:
Verified all scan positions for item responses and demographics to verify scanning setup and scan densities
Verified all constructed response score points, zoning of image, reader scoring, reader resolution, and reader check scores
Verified the handling of blank documents through the system
Test all demographic and item edits
Verified pre-id barcode read, match and no-match
Verified attemptedness rules applied by subtest
Verified duplicate student handling (same test duplicate, different test duplicate)
Verified duplicate student with different demographics rules applied
Verified the document counts to the enrollment, pre-id and actual document receipt
Verified pre-id matching and application to student record
Verified various raw score points and access to dummy and live scoring tables
Verified cut scores applied
Verified valid score on one subtest and invalid score on other subtest
Verified scoring applied to Braille and Large Print
Verified valid multiple choice and invalid constructed response
Verified valid constructed response and invalid multiple choice
Verified all special scoring rules
Verified all summary programs for rounding
Verified summary inclusion and exclusion (Braille, standard and non-standard student summarization)
Verified each scoring level for group reporting
Verified all reporting programs for accuracy in all text and data presented
Verified class, school, district, and state summary data on home reports
Verified all data file programs to assure valid information in every field
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
140
Verified data descriptions for accuracy against data file
Created compare programs to allow for update of files
The Maryland test deck was the first order processed through the Maryland system to verify all aspects of the materials packaging, scanning, editing, scoring, summary, and reporting. Pre-determined conditions were included in the test deck to assure the programs were processing all data to meet the requirements of the program with zero defects. Processing of live orders could not proceed until each phase of the test deck had been approved by our Quality Assurance department. An Issues Log with sign-off approvals was utilized to assure we were addressing any issues that arose in the review of the test deck data across all functional groups at Pearson.
Prior to release of any order for reporting we received a preliminary file from Scoring Operations to run a key check TRIAN to assure that all scoring keys had been determined and applied accurately. Any item that was not performing as expected was flagged and reviewed by our content specialist and psychometrician. Upon completion of the key check, we proceeded to run the pilot level reports.
We ran the pilot district utilizing live data. The pilot district included multiple buildings, all grades, and any unique accommodations. A formal pilot review process was conducted with Pearson staff experts prior to release of the information to MSDE.
Upon completion of the processing of all district-level data, Pearson Scoring Operations provided the Quality Assurance Department with one or more state-level data files, along with state data for review and approval. Pearson Quality Assurance programmers duplicated all data independently to ensure accurate interpretation of the expected results. A series of SAS programs were run on these files to ensure 100% accuracy. These included but were not limited to:
Statewide Duplicate Student
Statewide FD of Demographic Variables
District/Building/N-Count
Statewide RS/SS/Cut Score tables
Proc Means to verify summary statistics
Item Response listing to verify all constructed responses were scored and within the valid range
Normative data check for all raw scores
Reader Resolution report to verify all readings and resolution combinations
Upon complete review and approval by Quality Assurance, we posted the statewide student files to a secure FTP site for review by MSDE.

3. OVERVIEW OF STATISTICAL SUMMARIES
This section provides general information about statistical and psychometric summaries used for the 2011 MSA-Math program. Actual statistical results described in this section appear in section 4 and appendices.
3.1 Classical Descriptive Statistics
Table 4.1 contains the classical descriptive statistics of each form for each grade and includes:
Form number
Number of items
Numbers of students (These numbers were based on a whole population.)
Means and standard deviations of raw scores
Stratified Cronbach’s Alpha
Standard error of measurement (SEM)
Stratified Cronbach’s Alpha
The 2011 MSA-Math tests included SR, SPR, BCR, and ECR items. Consequently, it was necessary to use an adequate reliability coefficient that addressed the important factor, different item type. The following formula depicts the reliability coefficient, Stratified Cronbach’s Alpha:
Stratified 2
22 ))1(()1(((1
t
CRCRSRSR
σ
ρσρσα
where
2
SR = variance of score on SR and SPR items
2
CR = variance of score on BCR and ECR items
2
t = variance of total score
SR
= reliability coefficient of score on SR and SPR items, and
CR
= reliability coefficient of score on BCR and ECR items.

Standard Error of Measurement (Based on Classical Test Theory)
The standard error of measurement (SEM) is commonly used in interpreting and reporting individual test scores and score differences on tests (Harvill, 1991).
Classical test theory is based on the following assumptions (Andrich & Luo, 2004):
Each person v has a true score on the construct, usually denoted by the variable Tv
The best overall indicator of the person’s true score is the sum of the scores on the items and is usually denoted by the variable Xv
This observed score will have an error for each person which is usually denoted by Ev
These errors are not correlated with the true score
Across a population of people, the errors sum to 0 and they are normally distributed.
From these assumptions, the following equations can be derived:
vvv ETX .
Therefore,
2x = 2
t + 2e
where 2x = the variance of the observed score in a population of persons,
2t = the variance of their true score variance, and
2e = the error variance.
The reliability coefficient of the test can be calculated by the following formula:
x
= 2
2
x
t
= 2
22
x
ex
.
Thus, the SEM is calculated by the following formula:
e = x x1 .
For example, consider a student with a score of 90 from a sample of students with a mean score of 60 and variance of 225 on a test with reliability of 0.80. According to the formulas provided above, the obtained score is 90, and its SEM is 6.71. Thus, an approximate 68% score band for estimating this student’s true score is from 83.29 (90 - 6.71) to 96.71 (90 + 6.71).
Note that this equation is only useful to estimate true score when the test reliability is reasonably high and the obtained score for the examinee is not an extreme deviate from the mean of the appropriate reference group. When we use this equation, consequently, we should be careful with statements so that they do not imply greater precision than is actually involved (Harvill, 1991).

Conditional Standard Error of Ability Estimate (Based on the Rasch Model)
Under the Rasch (i.e., 1-PL IRT) model, the SE for each person is as follows (Andrich & Luo, 2004):
ˆ =
L
ivivi pp
1)1(
1
where
v = subscript for a person,
i = subscript for an item,
L = length of the test,
= ability estimate, and
vip = the probability that a person answers an item correctly and defined as follows:
vip = iv
iv
e
e
1 where v is person’s ability and i is item’s difficulty.
A confidence band can be found for use in interpreting the ability estimate. For example, an approximate 68% confidence interval for is given by
± SE
3.2 Scale Score Descriptive Statistics
Table 4.2 provides information about scale score descriptive statistics of each form for each grade and includes:
Form number
Numbers of students
Mean and standard deviation of scale scores
10% quantile (P10), 25% quantile (Q1), median (P50), 75% quantile (Q3), 90% quantile, and IQR (Interquantile Range= Q3-Q1)
Conditional standard errors (SE) at the cut scores (i.e., B/P and P/A)
In addition, Appendix B provides frequency distributions and histograms of the scale scores of the 2011 MSA-Math as well as the 2006 MSA-Math (i.e., base year assessment).
3.3 Classical and Rasch (1-Parameter Logistic IRT) Item Parameters
Appendix C provides both classical and Rasch item parameters and includes:
Item type (SR, SPR, BCR, or ECR)
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
154
P-value: in order for p-values of BCR and ECR items to be comparable with p-values of the SR and SPR items they were calculated as modified proportions of the maximum obtainable domain scores.
Point-biserial correlation: a Pearson’s r between the scored item and the total score
Rasch item difficulty estimate ( iD )
Conditional standard error of Rasch item difficulty estimate
Rasch step difficulty estimate (or structure calibration estimate, ijF )
Mean-square infit
Mean-square outfit
First of all, it should be noted that all the Rasch item and step difficulty parameters were placed on a common scale (i.e., the 2006 assessment since the 2006 was recalibrated using the Rasch model).
Second, the following formula shows how structure measure estimate ( ijD ) is calculated from
both iD and ijF directly obtained from a run of Winsteps:
ijD = iD + ijF ,
where ijD = structure measure estimate
iD = item difficulty estimate,
ijF = structure calibration estimate (i.e., step difficulty estimate).
Finally, the following formulas show how conditional standard error (SE) of item difficulty
estimate ( iD ) and structure measure estimate ( ijF ) were driven (Wright & Masters, 1982):

Fit Statistics for the Rasch Model
Fit statistics are used for evaluating the goodness-of-fit of a model to the data. Fit statistics are calculated by comparing the observed and expected trace lines obtained for an item after parameter estimates are obtained using a particular model. Winsteps provides two kinds of fit statistics called mean-squares that show the size of the randomness or amount of distortion of the measurement system.
Outfit mean-squares are influenced by outliers and are usually easy to diagnose and remedy. Infit mean-squares, on the other hand, are influenced by response patterns and are harder to diagnose and remedy. Table 3.1 provides a guideline for evaluating mean-square fit statistics (Linacre & Wright, 2000).
In general, mean-squares near 1.0 indicate little distortion of the measurement system, while values less than 1.0 indicate observations are too predictable (redundancy, model overfit). Values greater than 1.0 indicate unpredictability (unmodeled noise, model underfit).
Table 3.1. Criteria to Evaluate Mean-Square Fit Statistics
Mean-Square Interpretation
> 2.0 Distorts or degrades the measurement system
1.5 – 2.0 Unproductive for construction of measurement, but not degraded
0.5 – 1.5 Productive for measurement
< 0.5 Unproductive for measurement, but not degrading. May produce misleadingly good reliabilities and separations
3.4 Inter-Rater Reliability
Tables 4.15 through 4.20 contain information about the scoring agreement between two ratings received for each item. When the two readers assigned the same score to a student’s answer, the scores were in perfect agreement. Scores differed by one score point were adjacent, and scores differing by two or more score points were in discrepancy. For further information about inter-rater agreement, please see section 1.7, Scoring Procedures of the 2011 MSA-Math. While the perfect agreement rates of Step A were above 95%, those of Step B were above 78% for all items. It should also be noted that the agreement rates including both perfect and adjacent rates were above 98% for Step B for all items across all grades.
3.5 Correlations among Mathematics Standards
The 2011 MSA-Math consisted of five subscore reporting standards: Algebra, Geometry and Measurement, Statistics and Probability, Numbers and Computations, and Process. Tables 4.3 through 4.8 contain correlation coefficients among these math standards.

3.6 Decision Accuracy and Consistency at the Cut Scores
Tables 4.9 through 4.14 contain the results of analyses performed to estimate the accuracy and consistency of the decisions for passing (proficient) on the 2011 MSA-Math. The analyses make use of the methods outlined and implemented in Livingston and Lewis (1995), Haertel (1996), and Young and Yoon (1998).
The accuracy of a decision is the extent to which it would agree with the decisions that would be made if each student could somehow be tested with all possible parallel forms of the assessments. The consistency of a decision is the extent to which it would agree with the decisions that would be made if the students had taken a different form of the examination, equal in difficulty and covering the same content as the form they actually took.
Students can be misclassified in one of two ways. Students who were below the proficiency cut score, but were classified (on the basis of the assessment) as being above a cut score, are considered to be false positives. Students who were above the proficiency cut score, but were classified as being below a cut score, are considered to be false negatives.
For the 2011 MSA-Math, Tables 4.9 through 4.14 include:
Performance level
Accuracy classifications
False positives
False negatives
Consistency classifications
The tables illustrate the general rule that decision consistency was less than decision accuracy.
3.7 Differential Item Functioning
This section provides information about differential item functioning (DIF) analyses used for the 2011 MSA-Math. While the reference group was either male or Caucasian students, the focal group was either female or African-American students. It should be noted that DIF analyses on the 2011 operational items indicated that all the items were satisfactory. All the DIF results were archived in the 2011 Maryland item bank.
Since the 2011 MSA-Math was a mixed-format examination, comprised of SR, SPR, BCR, and ECR items, the DIF procedure used consists of the Mantel Chi-square (Mantel, 1963) for the BCR and ECR items and the Mantel-Haenszel procedure (Mantel & Haenszel, 1959) for the SR and SPR items.
Brief Constructed Response (BCR) and Extended Constructed Response (ECR) Items
To help interpret the Mantel Chi-square (Mantel 2 ), the Educational Testing Service (ETS) DIF procedure uses the Mantel statistic in conjunction with the standardized mean difference (SMD).
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
157
Mantel Statistic
The Mantel 2 is simply a conditional mean comparison of the ordered response categories for reference and focal groups combined over values of the matching variable score. By “ordered” we mean that a response of 1 on an item is higher than 0, a response of 2 is higher than 1, and so on. “Conditional,” on the other hand, refers to the comparison of members from the two groups who received the same score on the matching variable, i.e., the total test score in our analysis.
Table 3.2 shows a 2 T K contingency table, where T is the number of response categories and K is the number of levels of the matching variable. The values,
1y ,
2y , …,
Ty are the T
scores that can be gained on the item. The values, Ftkn and Rtkn , represent the numbers of focal
and reference groups who are at the thk level of the matching variable and gain an item score of
ty . The “+” indicates total number over a particular index (Zwick, Donoghue, & Grima, 1993).

2.
Under H0, the Mantel statistic has a chi-square distribution with one degree of freedom. In DIF applications, rejecting H0 suggests that the students of the reference and focal groups who are similar in overall test performance tend to differ in their mean performance. In the case of dichotomous items, on the other hand, the statistic is identical to the Mantel-Haenszel (1959) statistic without the continuity correction (Zwick, Donoghue, & Grima, 1993).
Standardized Mean Difference (SMD)
A summary statistic to accompany the Mantel approach is the standardized mean difference (SMD) between the reference and focal groups proposed by Dorans and Schmitt (1991). This statistic compares the means of the reference and focal groups, adjusting for differences in the distribution of the reference and focal group members across the values of the matching variable.

RK nyn
m )(1
, the mean item score of the focal group members at the thk
level, and
mRk = the analogous value for the reference group.
As can be seen from the equation above, the SMD is the difference between the unweighted item mean of the focal group and the weighted item mean of the reference group. The weights for the reference group are applied to make the weighted number of the reference group students the same as in the focal group within the same ability. A negative SMD value implies that the focal group has a lower mean item score than the reference group, conditional on the matching variable.

DIF classification for BCR and ECR items
The SMD is divided by the total group item standard deviation to obtain an effect-size value for the SMD. This effect-size SMD is then examined in conjunction with the Mantel 2 to obtain DIF classifications that are depicted in Table 3.3 below.
Table 3.3. DIF Classification for BCR and ECR Items
Category Description Criterion
AA No DIF Non-significant Mantel 2 or
Significant Mantel 2 and |SMD/SD| ≤ .17
BB Weak DIF Significant Mantel 2 and .17 < |SMD/SD| ≤ .25
CC Strong DIF Significant Mantel 2 and .25 < |SMD/SD|
Note. SD is the total group standard deviation of the item score in its original metric.
Selected Response (SR) and Student-Produced Response (SPR) Items
For the SR and SPR items, the Mantel-Haenszel Chi-square (M-H 2 ) is used in conjunction with the M-H odds ratio transferred to what ETS calls the delta scale (D).
The Odds Ratio
The odds of a correct response are P/Q or P/(1-P). The odds ratio, on the other hand, is simply the odds of a correct response of the reference group divided by the odds of a correct response of the focal group.
For a given item, the odds ratio is defined as follows:
HM = QfP
QP
f
rr
/
/.
The corresponding null hypothesis is that the odds of getting the item correct are equal for the two groups. Thus, the odds ratio is equal to 1:
H0: HM = QfP
QP
f
rr
/
/ = 1.
Maryland School Assessment-Mathematics: Grades 3 through 8 2011 Administration
160
The Delta Scale
In order to make the odds ratio symmetrical around zero with its range being in the interval to , the odds ratio is transformed into a log odds ratio as per the following:
HM = )ln( H-M .
The simple natural logarithm transformation of this odds ratio is symmetrical about zero in which zero has the interpretation of equal odds. This DIF measure is a signed index where a positive value signifies DIF in favor of the reference group while a negative value indicates DIF
in favor of the focal group. HM also has the advantage of being transformed linearly to other
interval scale metrics (Camilli & Shepard, 1994). This fact is utilized by ETS in creating their delta scale (D), which is defined as follows:
D = .35.2 HM
DIF classification for SR and SPR items
The following table depicts DIF classifications for SR items to examine the M-H 2 in conjunction with the delta scale (D):

3.8 Equating and Scaling
Tables 4.21 through 4.44 contain the 2011 MSA-Math total raw score to scale score (RS/SS) conversion tables. Conditional standard errors for the total scale scores are also included. It should be noted that each student’s total raw score for the strands was a summation of the individual item score within a strand level. The strand levels were classified as stated in section 1.4 and the item parameters within each strand was obtained using the Winsteps program in the same manner as those obtained for the total test. Once the item parameters were available, thetas (student proficiency scores) were calculated for each raw score point that could be obtained within each strand. The thetas were transferred to scale scores, using the same slope and intercept as that which were applied for the total math test score.
The Rasch and Partial Credit Models
The most basic expression of the Rasch model is in the item characteristic curve (ICC). It shows the probability of a correct response to an item as a function of the proficiency level. The probability of a correct response is bounded by 1 (certainty of a correct response) and 0 (certainty of an incorrect response).

As an example, consider Figure 3.1 which depicts an item that falls at approximately 0.85 on the proficiency (horizontal) scale. When a person answers an item at the same level as their proficiency, then that person has a probability of roughly 50% of answering the item correctly. Another way of expressing this is that if we have a group of 100 people, all of whom have an proficiency of 0.85, we would expect about 50% of them to answer the item correctly. A person whose proficiency was above 0.85 would a higher probability of getting the item right, while a person whose proficiency is below 0.85 would have a lower probability of getting the item right. This makes intuitive sense and is the basic formulation of Rasch measurement for test items having only 2 possible categories (i.e., wrong or right).
Figure 3.2. Category Response Curves for a One-Step Item
Figure 3.2 extends this formulation to show the probabilities of obtaining a wrong answer or a right answer. The curve on the left (j = 0) shows the probability of getting a score of “0” while the curve on the right (j = 1) shows the probability of getting a score of “1”. The point at which the two curves cross indicates the transition point on the proficiency scale where the most likely response changes from a “0” to a “1”. Here, the probability of answering the item correctly is 50%.
The key step in the formulation, and the point at which the Rasch dichotomous model merges with the PCM, requires us to assume an additional response category. Suppose that, rather than scoring items as completely wrong or completely right, we add a category representing answers that, though not totally correct, are still clearly not totally incorrect. These relationships are shown in Figure 3.3.

The left-most curve (j = 0) in Figure 3.3 represents the probability for all examinees getting a score of “0” (completely incorrect) on the item, given their proficiency. Those of very low proficiency (i.e., below – 2) are very likely to be in this category and, in fact, are more likely to be in this category than the other two. Those receiving a “1” (partial credit) tend to fall in the middle range of abilities (the middle curve, j = 1). The final, right-most curve (j = 2) represents the probability for those receiving scores of “2” (completely correct). Very high-proficiency people are clearly more likely to be in this category than in any other, but there are still some of average and low proficiency that can get full credit for the item.
Figure 3.3. Category Response Curves for a Two-Step Item
Although the actual computations are quite complex, the points at which lines cross each other have a similar interpretation as for the dichotomous case. Consider the point at which the j = 0 line crosses the j = 1 line, indicated by the left arrow. For abilities to the left of (or less than) this point, the probability is greatest for a “0” response. To the right of (or above) this point, and up to the point at which the j = 1 and j = 2 lines cross (marked by the right arrow), the most likely response is a “1”. For abilities to the right of this point, the most likely response is a “2”.
Note that the probability of scoring a “1” response (j = 1) declines in both directions as proficiency decreases to the low extreme or increases to the high extreme. These points then may be thought of as the difficulties of crossing the thresholds between categories.

An important implication of the formulation can be summarized as follows: If the commonly used Rasch model applied to dichotomously (right/wrong) scored items can be thought of as simply a special case of the PCM, then the act of scaling multiple-choice items together with polytomous items, whether they have three or more response categories, is a straightforward process of applying the measurement model. The quality of the scaling can then be assessed in terms of known procedures.
One important property of the PCM is its proficiency to separate the estimation of item/task parameters from the person parameters. With the PCM, as with the Rasch model, the total score given by the sum of the categories in which a person responds is a sufficient statistic for estimating person proficiency (i.e., no additional information need be estimated). The total number of responses across examinees in a particular category is a sufficient statistic for estimating the step difficulty for that category. Thus with PCM, the same total score will yield the same proficiency estimate for different examinees.
The PCM is a direct extension of the dichotomous one-parameter logistic IRT model developed by Rasch (Rasch, 1980). For an item/task involving mi score categories, one general expression for the probability of scoring x on item/task i is given by

The above equation gives the probability of scoring x on the i-th test item as a function of proficiency ( ) and the difficulty of the mi steps of the task (Masters, 1982).
According to this model, the probability of an examinee scoring in a particular category (step) is the sum of the logit (log-odds) differences between and Dij of all the completed steps, divided by the sum of the differences of all the steps of a task. Thissen and Steinberg (1986) refers to this model as a divide-by-total model. The parameters estimated by this model are (1) an proficiency estimate for each person (or proficiency estimate at each raw score level) and (2) mi threshold (difficulty) estimates for each task with mi + 1 score categories.

A. APPENDIX A: THE 2011 MSA-MATH STRATIFIED RANDOM SAMPLING
Since reporting deadlines made it difficult to use the Maryland school population as calibration and equating data set, Pearson used equating samples instead of the population using stratified random sampling method across all the grades.
Pearson chose Local Education Agency (LEA) as one of the most important variables for stratification. Based on the population percentage of each LEA, Pearson randomly selected about 3,000 students for those grades from first-waved documents (i.e., 50% of the statewide population) which were randomly distributed and completely scored. It should be noted that this method has been applied since the 2006 assessment.
To verify that the sample was representative of the statewide examinee population in terms of gender and ethnicity, the distributions of gender and ethnicity of the 2011 samples were compared with the 2011 population. The results are shown in this Appendix. The percentages of students from the LEAs were all within 2 percentage point of the target values across all grades. The percentages of students from the five major ethnic groups were all within 6 percentage points of the target values across all grades. The percentages of male and female students were within 2 percentage points of the target values across all grades. Consequently, we concluded that the 2011 equating samples were representative of the 2011 statewide examinee population in terms of LEA, gender, and ethnicity.
