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 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.
