Summary:
Dover, Massachusetts has exactly one public high school: Dover-Sherborn Regional High, which serves grades 9–12 with 610 students and belongs to the Dover-Sherborn district. Because there is only one high school in town, this is a profile of a single school rather than a comparison among local options — and families here are served by a school that consistently ranks among the very best in the state.
Dover-Sherborn Regional High has been in the top 10 of Massachusetts high schools in each of the three reported years: #1 of 349 schools in 2024–2025, #2 of 353 in 2025–2026, and #8 of 348 in 2023–2024, earning a 5-star rating every year. The Dover-Sherborn district ranks #4 of 351 districts statewide. MCAS proficiency is roughly double the state rate in every reported subject and year. In 2025–2026, 87.97% of 10th graders were proficient in math (state: 43.73%), 87.22% in English language arts (state: 45.48%), 83.21% in science (state: 40.5%), and 86.88% in end-of-course biology (state: 37.68%) — the largest gap, at +49.20 points. The school's edge over its own district is modest, generally +1.3 to +3.1 points, but the district's edge over the state is large, about +39.7 to +47.2 points.
Graduation and dropout figures are strong: a 99.4% graduation rate at the school and 98.1% district-wide in 2024–2025, with 0.0% dropout rates at both. The student-teacher ratio is 9.8, suggesting relatively small classes, and per-student spending is listed at $21,791 for 2020–2021. Two cautions for parents: the free/reduced-lunch percentage is not reported, so socioeconomic and equity comparisons are not possible from this data, and 10th-grade scores eased from 2024–2025 to 2025–2026 (ELA down 6.21 points, math down 1.08, science down 3.91), though the school still ranked #2 in the state.
