NOTES from the state website:

For multi-school districts, school results include students enrolled for the entire academic school year; district results include all tested students.

For single-school districts, MCAS results include all students tested in the district. It is fairest to compare results from single-school districts to other district results, rather than to school-level results.

3 Burlington students in grades 3-8 participated in the PARCC field tests in ELA and math and were exempt from the spring 2014 MCAS test administration in both subjects.
