Option announced by USED in Sept Removes requirement for Adequate Yearly Progress (AYP) rating. States can propose their own system of School Accountability Supports and Interventions Targets interventions toward 15% of Title I schools (about 90 schools) 2
Include individual student growth. Several growth models were reviewed. Colorado Growth Model chosen for implementation. Use an overall rating system (including growth) to identify Priority, Focus, and Model Schools. Several possible methodologies were reviewed. Modified Colorado school rating system chosen for implementation. Rating system is prototype for future report cards. 3
Uses the Colorado Growth Model. Includes all students having two consecutive years of standard OAKS assessments, regardless of whether or not they are meeting standard. A student’s growth is compared to the growth of other students in the state having the same prior test scores (“Academic Peers”) Student Growth is expressed as a percentile. A growth percentile of 75 would mean the students growth was as high or higher than 75 percent of his/her academic peers. Computes Growth Targets – growth percentiles that put a student on track to be at standard in three years. 4
Growth is based on comparing a student to his or her Academic Peers, who are students with the same test score histories. Growth of low performing students is compared to that of other low performing students in the state. Growth of high performing students is compared to that of other high performing students in the state. Growth model applies to students in grades 4 to 8, and 11. Uses up to four years of test data for each student. 5
Schools are given “Levels” in reading and math growth: Level 5: Schools with high growth Level 4: Average to above average growth Level 3: Below average, but not low, growth Level 2: Low growth Level 1: Very low growth Reading and math growth are combined into a Growth Rating. 6
School accountability uses the median growth percentile. Median growth is the “middle” growth percentile. This is the “typical” growth at the school. We also report the median target growth percentile. A school has “On Track” growth if the median growth percentile is as high as the median target percentile. “On Track” growth indicates that a typical student is meeting his/her growth target. Requirements to reach Level 5, Level 4, etc., are lower for schools with “On Track” growth. 7

The students in red are shown to emphasize that growth is evaluated relative to academic peers, not on absolute gains in test scores.

Growth targets are forward looking. They estimate the growth necessary to meet in three more years, or by grade 11. They are provided both as percentiles and as RIT scores. The RIT score represents the typical score attained by students who grew to standard in the past. The percentile should be viewed as an estimate of the difficulty of attaining the goal.
