Definition: Percentage difference, calculated as (2015 rate – 2010 rate) divided by 2010 rate

Data Source: Mass Department of Elementary and Secondary Education, 2010-2016 MCAS Reports; Mass Department of Elementary and Secondary Education, 2010, 2014, 2015 Reports

Footnote: The calculation only includes schools that were continually operating from 2010 to 2015. Map is displayed by pixel. It averages the rate/score in a certain size of pixels. In some cases, the percentage will be an infinite number because the rate/score in 2010 (base year) is not available or 0. In these cases, the percentage is coded as 100%. For schools who do not have data from both 2010 and 2015, they were coded as 0%.
