Summary:
ZIP code 02030 covers Dover, Massachusetts, and contains exactly one middle school: Dover-Sherborn Regional Middle School, which serves grades 6–8, enrolls 471 students, and is located at 155 Farm Street in Dover as part of the Dover-Sherborn district.
This school is a consistent top performer. It earned a 5-star rating in each of the last three years, ranking 20th of 478 schools (96th percentile) in 2025–26, 27th of 484 (94th percentile) in 2024–25, and 18th of 493 (96th percentile) in 2023–24. Its district ranks 4th of 351 districts statewide — the 99th percentile — with 5 stars. Proficiency is far above state averages in 2025–26: ELA at 74.08% versus the state's 40.03%, Math at 75.74% versus 41.11%, Science at 65.91% versus 40.98%, and 8th-grade Civics at 73.88% versus 39.77%. The largest relative gap is 7th-grade Math, where the school scores 77.40% against a state rate of 37.48% — a difference of nearly 40 percentage points — while 6th-grade Math is the highest absolute score at 79.01%. Because there is only one school in this ZIP code, the most useful comparison is against district and state benchmarks, and the school exceeds them in every reported subject.
Year over year, ELA rose 3.34 points, Math rose 3.47 points, and Civics rose 4.74 points, while Science declined 5.69 points, from 71.60% to 65.91% — a pattern that mirrors the district's own Science results. The student-teacher ratio is a favorable 9.4:1 in 2024–25, and per-pupil spending was $21,388 in 2020–21, though that spending figure is older than the test data and no state comparator is provided. The free/reduced-lunch field is blank for 2024–25, so it should be read as unavailable rather than as 0%. Overall, families in this area have access to a highly ranked, 5-star school with proficiency well above state levels; the Science decline is the main item worth watching.
