How does the median student growth percentile relate to the Composite Performance Index?
The Composite Performance Index (CPI) describes a group of students’ progress toward proficiency based on the students’ current level of performance. Students are assigned points based on how close they are to proficiency. All students scoring Proficient and above receive the same score of 100; because of this, the measure is not sensitive to changes in performance among students who have attained Proficient or Advanced. Changes in a group’s CPI over time can show its progress toward proficiency. The median student growth percentile describes a group’s progress in terms of its students’ change in performance relative to the prior year, as compared to that of their academic peers. Thus it is more directly related to changes in CPI than it is to the CPI level itself. It also captures growth at all levels of performance, not just among students below Proficient. And finally, it is calculated for a narrower range of students-only those with at least one year of prior test history. As a res
