Footnote: MCAS refers to Massachusetts Comprehensive Assessment system. It is a statewide standards-based assessment program, that State and federal law mandates that all students who are enrolled in the tested grades and who are educated with Massachusetts public funds participate in it. The proficiency rate is calculated as total number of students who got Advanced/Proficient divided by total students who participated in MCAS. The final categories (very high/high/moderate/low/very low) are determined by sorting all schools within Boston metro into quintiles based on their proficiency rates. The top 20% of the schools were identified as “very high”. Conversely, the least 20% is categorized as “very low”. Some students who participated in the PARCC test were not included. Over the six years period, some schools were closed/opened/moved, so that it’s hard to track over the past six years for those newly opened/closed schools. The time range only applies to schools that were continuously operating from 2010 to 2016. The animation averaged the proficiency rates within certain pixels and displayed by time series. Data in 2015 and 2016 is not complete.
