Kindergarten entry age
Massachusetts leaves the kindergarten entry cutoff to local districts, so the date can differ between neighboring towns. Check your district's enrollment page.

Instructional-time rules decide how many missed days must be made up — the reason a winter with several snow days can push the last day of school later. Count down to yours with the Days Until Summer tool.
Grading scale
We did not find a statewide grading scale for Massachusetts — in most states the scale is set by the district or even the school, and many use 90/80/70/60 or a plus/minus variant. Check your student handbook, then convert scores with our grading scale converter.
Snow days and remote learning
Boston (Logan) averages about 49.2 inches of snow a year (1991–2020 normals, source), which puts Massachusetts in our heavy snow tier. Districts used to heavy snow need more of it to close; places that rarely see snow close for less.
