Kindergarten entry age

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 New Hampshire — 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
Concord (capital) averages about 67.7 inches of snow a year (1991–2020 normals, source), which puts New Hampshire in our heavy snow tier. Districts used to heavy snow need more of it to close; places that rarely see snow close for less.
N.H. Admin. Code Ed 306.18(c)(1): remote learning counts toward the requirement when inclement weather makes student transport unsafe. No cap stated. Schools must schedule 60 extra hours, at least 30 of them for weather/emergency make-up. Source.
