Colorado Growth Model & SchoolView
(Brief Introduction)
Developed by CDE and the National Center for the Improvement of Educational Assessment.
Measures growth for every student (regardless of where they start), comparing individual students to others who have the same score history.
Measures student-level “growth to standard” to determine if students are on track to be ready by exit
The model includes metrics for individual students, disaggregated groups of students, schools, and districts.
The growth model is the centerpiece of our State Accountability System (50%-75% of accreditation ratings).
Growth Model History
2 *Adopted from Center for Transforming Learning and Teaching presentation (2012)
Questions Addressed by the Growth Model
What is?
• How much growth did a student make in one year?
What could be?
• How did this student’s growth compare to other students with a similar score history? Was it low, typical or high?
What should
be?
• Did the student grow enough to be on track to be proficient within three years?
Individual Student Growth

Colorado Growth Model (CGM)
A statistical model to calculate each student’s progress on state assessments over time.
The student growth percentile tells us how a student's current test score compares with those of other similar students (students across the state whose previous test scores are similar).
Student growth percentiles are calculated using a complex statistical model (i.e. quantile regression) while being conceptually simple to understand.
Individual Student Growth Percentiles
High at or above 66th percentile
Typical at or between the 35th and 65th percentile
Low up to and including 34th percentile

Individual Student Report
Exploring Individual Student Reports
Answer the following questions:
How many years of achievement results are available for this student? How many years of growth?
What were this student’s growth percentiles for each year in math? In reading?
When did this student make low, typical or high growth?
What level of growth would this student need to make to move proficiency levels for the next year in math? In reading?
Catch-Up & Keep-Up Growth
To be eligible for and to make catch-up growth: The student scores below proficient (unsatisfactory or partially proficient) in the previous
year.
The student demonstrates growth adequate to reach proficient performance within the next three years or by 10th grade, whichever comes first.
To be eligible for and to make keep-up growth:
The student scores at the proficient or advanced level in the previous year. The student demonstrates growth adequate to maintain proficiency for the next three years or until 10th grade, whichever comes first.
