The CPI is:
• a metric that is used to measure school and district performance and improvement;
• a 100-point index that combines the scores of students who participate in standard MCAS ELA and mathematics tests, and those who participate in the MCAS-Alt.
MCAS Performance Level Scaled Score Range

MCAS-Alt Performance Level Points Per Student
Proficient or Advanced 240 – 280 Progressing 100
Needs Improvement High 230 – 238 Emerging 75
Needs Improvement Low 220 – 228 Awareness 50

Composite Performance Index (CPI)
Multiply the number of points by the number of students at each performance level, then divide the total number of points by the total number of students (example below)
