2018 Accountability Classification

Massachusetts uses information related to progress toward improvement targets, accountability percentiles, graduation rates, and assessment participation rates to determine each district and school’s overall classification. Most districts and schools are placed into two categories: those that require assistance or intervention from the state, and those that do not require assistance or intervention. Districts and schools that are new or very small are classified as having 'insufficient data'. Placing schools and districts into categories helps districts know which schools need more support, and helps the state know which districts need the most assistance.

2018 Student Achievement

Legacy MCAS (CPI)

The Composite Performance Index (CPI) is a number from 1-100 that represents the extent to which students have attained or are progressing toward proficiency in a given subject. Students who demonstrate proficiency on MCAS tests, and students with severe cognitive disabilities who score at the Progressing level on the MCAS-Alternate assessment, receive 100 CPI points. Our school's CPIs for 2018 are below.
