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 Models
How much do students need to grow each year to
reach Proficiency
Value

added Models
Did the school or teacher cause an amount of
learning growth that is statistically above, at, or below
expectation
Student Growth Percentile Models
How 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 2
nd
to 11
th
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.

Measuring Student Learning Growth in
The College Ready Promise Schools:
Reviewing Objectives
1.
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.
S
tudent 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
