Slosson Intelligence Test

What?

Why?How?



Overview

IQ test

SIT-R uses calibrated norms for ages 4 toadult

Good diagnostic tool to identify students

needing further evaluation. Student candidates for testing



Intended Purpose of Slosson

SIT-R is intended to be a screening test ofintelligence specifically measuring theverbal intelligence factor.

Six domains include: vocabulary, generalinformation, similarities and differences,comprehension, quantitative, reasoning,

auditory memory.



SIT-R Model

Crystallized Intelligence Memory

Verbal Quantitative

Vocabulary Quantitative Auditory

General information MemorySimilarities and Differences

Comprehension



Vocabulary (VO)

Ability to use, understand and definewords orally.

Age 7 sample question, “What doesdangerous mean?”



General Information (GI)

Reflects the learning of culturalknowledge, much or which is not explicitlyor directly taught.

Age 7 sample question, “What is papermade of?”



Similarities and Differences (SD)

This cognitive area reflects one’s skill indetermining common attributes of twodissimilar things or concepts and also

some uncommon attributes.

Age 7 sample question, “How are anairplane and a balloon the same? How are

an airplane and a balloon different?”



Comprehension (CO)

Reflects one’s knowledge of socialbehavior, “common sense” and ability tointerpret sayings and proverbs.

Age 8 sample question, “Why do we needto cook some food before we eat it?”



Quantitative (QN)

Reflects ability to do mental calculations,remember the essential numbers,determine the arithmetic process required,

and calculate the correct answer.

Age 7 sample question, “Jim had sixmarbles and he got two more. How many

does he have altogether?”



Auditory Memory (AM)

Reflects one’s ability to remember andrepeat correctly a random series of digits,both forward and backwards, and several

sentences.

Age 7 sample, “Say these numbersbackwards: 4, 7, 3.”



Question Validity

Proven reliable test: Uses same kinds ofitems accepted on other cognitive aptitudetests. Example - The Binet.

Examples of every domain (GI, VO, etc.)found at least once out of every tenquestions.



Reliability

Test score components: True scorevariance, item specific variance and error.

Estimating reliability are attempts todemonstrate the consistency with whichtest items measure some common factors-No test is 100% accurate!

Standard error of measure: 10 points.



Slosson Instruction

Individual test form

Helpful checklists for administrators

Note: #s 2, 6, 11, 19, 25

Underline key words for # 1 - 25

Chronological age of student – Page 8

Individual test form activity- 15 minutes

Reference pages: 32 – 39 ages 16+

Sample copy of Total standard score – page 34



Total Standard Scores

Scoring tables: Using the extreme right or leftcolumn of individual’s raw score, locate columnthat describes his/her age.

Basal Item: Question number at which the

student answers ten consecutive questions – refer to page 8.

Total number: Questions correct after BasalItem.

Correct questions after basal =s raw score. Ceiling Item: Last correct item.



Test Results

Chronological age (CA) + Raw Score =

Total Standard Score (TSS) - Table A

Mean age equivalent (MAE) - Table B

T-Score – Table C Normal Curve Equivalent (NCE) - TSS Score

NCE found in Table C

Stanine Category – Table C Percentile Ranking – Table C

Confidence Interval – Table D



Giving the Test

Read questions exactly as written.

Mark the answer sheet 0 for incorrect and1 for correct.

Once the student has answered 10consecutive questions incorrectly, theyhave completed the test.
