Summary:
Dover-Sherborn contains just one middle school — Dover-Sherborn Regional Middle School in Dover, MA — serving grades 6–8 with 471 students as part of the Dover-Sherborn district, which ranks 4th out of 351 Massachusetts districts, at the 99th percentile with a 5-star rating.
That single school ranks among the best middle schools in the state. Its statewide rank history shows 20th of 478 (96th percentile, 5 stars) in 2025–2026, 27th of 484 (94th percentile, 5 stars) in 2024–2025, and 18th of 493 (96th percentile, 5 stars) in 2023–2024 — 5 stars every reported year. MCAS proficiency sits far above state averages in every reported subject and grade. In 2025–2026, all-grade ELA was 74.08% proficient versus 40.03% statewide, mathematics 75.74% vs. 41.11%, science 65.91% vs. 40.98%, and 8th grade civics 73.88% vs. 39.77%. Every reported subject and grade is at least about 25 percentage points above the state, with most 30 or more points above; the smallest gap is 8th grade science at +26.98 points.
Mathematics is the strongest area: all-grade math is the highest all-grade result at 75.74%, grade 7 math has the biggest school-versus-state gap (+39.92 points), and grade 6 math is the highest single reported score at 79.01%. ELA rose 3.34 points year over year, and 8th grade civics rebounded 4.74 points. Science slipped 5.69 points to 65.91%, the lowest all-grade result, though still well above the state, and the district figure matches exactly — consistent with a cohort pattern rather than a school-specific issue. The school generally matches or slightly exceeds district averages. The student-teacher ratio is 9.4, per-student spending was $21,388 in 2020–2021, and free/reduced lunch data is blank, so economic context is unknown.
