Definitions:
• 1SGP: Student Growth Percentile is “a measure of student progress that compares changes in a student’s MCAS scores to changes in MCAS scores of other students with similar scores in prior years.” (from the Massachusetts Department of Elementary and Secondary Education’s MCAS Student Growth Percentiles: Interpretive Guide, March 2011)
• 2CPI: Composite Performance Index is a “100-point index that assigns 100, 75, 50, 25, or 0 points to each student participating in MCAS and MCAS-Alt tests based on their performance. The total points assigned to each student are added together and the sum is divided by the total number of students assessed. The result is a number between 0 and 100, which constitutes a district, school or group’s CPI for that subject and student group. The CPI is a measure of the extent to which students are progressing toward proficiency (a CPI of 100) in ELA and mathematics. CPIs are generated separately for ELA and mathematics, and at all levels – state, district, school, and student group.” (from the Massachusetts Department of Elementary and Secondary Education’s 2010 Glossary of Accountability Reporting Terms)
