  2. Purpose The Colorado Growth Model is intended to: • Statistically measure students’ progress on state assessments. • Act as a tool to compare student and student group data for the state, educators, and the public. • Students can be grouped by school, district, or other common factors. • Student groups must be larger than 20 students in order to maintain student confidentiality • Provide the data necessary to calculate adequate yearly progress.

  3. Observed Growth Calculation • Student growth is measured in student growth percentiles • Student growth percentiles are calculated by comparing a student’s current test scores to those of students that have similar test score history • Similar to child height and weight percentiles, student growth percentile provide a straight-forward interpretation of academic growth. Example: If a student has a 55% academic growth percentile, he grew better than 55% of his academic peers.

  4. Growth Percentile Interpretations • Adequate Growth: observed growth that indicates that a student remains proficient or is on track to be proficient • Low growth: < 35th growth percentile • Typical growth: 35th growth percentile – 65th growth percentile • High growth: > 65th growth percentile

  5. Growth Percentile Interpretations • Catch Up Students: students that previously scored Unsatisfactory or Partially Proficient that have shown enough growth to be Proficient in 3 years or by 10th grade (whichever comes first) • Keep Up Students: students that previously scored Proficient that have shown enough growth to remain Proficient in 3 years or by 10th grade (whichever comes first) • Moving Up Students: students that previously scored Proficient that have shown enough growth to be Advanced in 3 years or by 10th grade (whichever comes first)
