Summary

Groton Dunstable Regional Middle is a grades 5–8 school in Groton, MA, enrolling 739 students as part of the Groton-Dunstable district. By state standards it is strong: in 2025–2026 it ranked 98th of 478 Massachusetts middle schools (79th percentile, 4 stars), while its district ranks 34th of 351 districts (90th percentile, 5 stars). The school has generally been a 4-star school, with 5-star years in 2016–2017 and 2020–2021; the 2025–2026 rank is its lowest since 2017–2018. All core MCAS subject scores are above state averages, but the school is not at the top of its nearby comparison group.

Among nearby middle schools, Groton Dunstable ranks ahead of Lunenburg Middle School, Ayer Shirley Regional Middle School, Nissitissit Middle School, Sky View Middle School, and Hawthorne Brook, but behind The Bromfield Middle School, Stony Brook School, Blanchard Middle, and Littleton Middle School in overall rank and most MCAS subjects. Science is its clear strength at 62.14% proficiency — 21.16 points above the state — and the only subject slightly above the district's all-grade average. Math (54.97%) and ELA (51.13%) are well above state but below the district average; Math has trailed the district in each recent year, and ELA dropped 8.48 points from 2024–2025. Grade 7 Math (66.67%) and Grade 5 Science (64.97%) are standout results, while Grade 6 Math (47.13%) and Grade 5 ELA (44.89%) are relative soft spots — still above state, but closer to the line.

Results for specific student groups stand out: in 2025–2026 the school ranked in the 82nd percentile for Special Education students and the 75th percentile for Low Socio Economic Status students, and results for female (80th percentile) and male (78th percentile) students are closely balanced. The student-teacher ratio was 12.8 in 2024–2025, mid-range among nearby schools, and per-student spending was $18,468 in 2020–2021 — higher than the nearby schools with reported spending. Even so, it does not outperform Littleton Middle School or the Westford schools in rank or most MCAS subjects. Free/reduced-lunch percentages were not available for any year, limiting direct socioeconomic context.
