How Annual and Cumulative PPIs are Calculated
The annual PPI is a measure of the improvement that a group makes toward its own targets over a two-year period on up to seven different indicators. Groups are eligible for an annual PPI if a sufficient number of students were assessed (20 for schools, 30 for subgroups) in English language arts and mathematics in the most recent year and one of the two prior years. A group is awarded 0, 25, 50, 75, or 100 points based on the amount of improvement it makes from one year to the next:
100Above Target25No ChangeA group can earn extra credit for reducing the percentage of students scoring Warning/Failing and/or by increasing the percentage of students scoring Advanced by 10% or more on ELA, mathematics, or science MCAS tests. An additional 25 points for meeting each of these goals is added to the total number of points awarded.
75On Target0Declined
50Improved Below Target-Insufficient Data
The annual PPI is calculated by dividing the total number of points awarded by the number of indicators (up to seven). The cumulative PPI is the average of a group's annual PPIs over the most recent four year period, weighting later years the most (1-2-3-4). A group is assigned a cumulative PPI if it has three annual PPIs. While a group's annual PPI can exceed 100 points, the cumulative PPI is always reported on a 100-point scale. For a group to be considered to be making progress toward narrowing proficiency gaps, its cumulative PPI must be 75 or higher.
