Agenda
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.
