Colorado Growth Model (CGM)– DCSD Results

CCHE Remediation Report

CGM—Background

• HB 07-1048: Longitudinal Analysis of Student Assessments (Feb. 2007)

• Continued work started in 2004 (HB 04-1433)

• Technical Advisory Panel developed the growth model

• State Board adopted growth model March 6, 2008

• School awards based on the growth model

CGM—Student Level

Academic Peers

A child’s progress is being compared with students who had similar academic results on state tests in previous years.

CGM—Student Level

Growth Percentile: A child’s growth is measured by how fast they progressed compared with their academic peers. If a student has a growth percentile of 55, they made better progress than 55 percent of their academic peers.

CGM—Student Level

Growth Percentiles are a measure of growth……

NOT a measure of achievement

CGM—Student Level

Typical growth is represented by the percentile range

Typical = 35th to 65th percentile High = above 65th

Low = below 35th percentile

35th 50th 65th

CGM—Student Level

Adequate growth is the growth necessary to achieve proficiency within three years or by the 10th grade.

CGM—Student Example

CGM VS DCSD Model

● DCSD Growth Model● Uses CSAP Scale Score

● Criterion Referenced

● Static Measure

● Colorado Growth Model● Norm Referenced

● Performance of Academic Peers

● Dynamic Measure

CGM—School Level

Median student growth percentile is the growth measure for schools.
