About this report

Overall classification: All Massachusetts districts and schools with sufficient data are classified into one of two accountability categories: districts and schools requiring assistance or intervention, and districts and schools not requiring assistance or intervention. The reason(s) for the district's or school's classification are noted on this report.

Progress toward improvement targets: The criterion-referenced target percentage combines multiple years of data related to achievement, growth, high school completion, English learner progress, advanced coursework completion, and chronic absenteeism into a single number between 0 and 100. For a group to be considered to be meeting targets it must have a cumulative criterion-referenced target percentage of 75% or higher.

The annual criterion-referenced target percentage is calculated by dividing the weighted total points earned by the weighted total possible points. The calculation for each is displayed below.

Weighted total of points earned = (Total achievement points earned x Achievement weight) + (Total growth points earned x Growth weight) + (Total high school completion points earned x high school completion weight) + (EL progress points earned x EL progress weight) + (Total additional indicator points earned x Additional indicator weight)

The cumulative criterion-referenced target percentage represents a weighted average of the annual criterion-referenced target percentages. At a minimum, a group must have an annual criterion-referenced target percentage for the most recent year in order to receive a cumulative percentage.

Accountability percentile: An accountability percentile between 1 and 99 is reported for most schools. This number is an indication of the school's overall performance relative to other schools that serve similar grades, and is calculated using multiple years of data for all accountability indicators. School percentiles are not calculated for districts.
