Measuring Student Learning Growth in The College Ready Promise Schools:

Our Objectives

1. Review the TCRP theoretical framework?

2. What are multiple measure and how is it used to assess teacher performance?

3. How can student learning growth be measured?

4. How will The College Ready Promise report student, teacher and school learning (reading and interpreting the teacher report)?

• Achievement results tell us what each student knows at a single point in time.

• Student learning growth tells us how much each student progresses from one year to the next.

• Both types of information are important.

How is Learning Growth Being Measured Across the United States?

Growth to Standard ModelsHow much do students need to grow each year to reach Proficiency

Value-added ModelsDid the school or teacher cause an amount of learning growth that is statistically above, at, or below expectation

Student Growth Percentile ModelsHow much do students grow compared to similar students

What are Student Growth Percentiles?

• measure how much a student has learned from one year to the next compared to other students with similar test scores

• expressed as a percentile from 1 to 99

Key Concepts about Measuring Growth

1. Growth is distinct from achievement A student can achieve at a low level but grow quickly, and vice versa (Jimmy, Rosa, Elijah)

2. Each student is compared only to their academic peers (students with similar achievement levels)

The comparison base for TCRP is all 2nd to 11th grade students in TCRP & LAUSD

3. Demographic variables, socio-economic status and initial achievement have virtually no impact on student growth results.

• Imagine that the list of students to the left are all the students in your 7th grade class.

• Note that the SGPs are sorted from lowest to highest.

• The point where 50% of students have a higher SGP, and 50% have a lower SGP is the median.

• Median SGP for this 7th grade class is 55.

Practice Find the median SGP of the following group of students.

Hint: Place the scores from lowest to highest. If the middle number is the “median”. If there is an even number of scores, take mean/ average of the 2 middle scores.

Ranges for teacher SGP used to determine teacher effectiveness levels were selected based on statistical evaluation.

Reading the Teacher Report

• To gain a better understanding of how to read the Teacher Report

• To analyze the data

• To interpret the data

• To make decisions based on the data

Measuring Student Learning Growth in The College Ready Promise Schools:

Reviewing Objectives1. The TCRP theoretical framework has a goal of improving

student achievement.

2. The multiple measures used to assess teacher performance are SGP, teacher practice, student feedback, and family feedback.

3. Student learning growth is measured by SGP (student growth percentiles)

4. SGP is growth measured with a cohort of academic peers from one year to the next, using CST results.

5. The College Ready Promise reports includes 4 elements: school and department means, valid scores, a scatter plot, and student roster
