Summary:
Zip code 01450 is served by three public schools: Florence Roche School (elementary, K–4), Groton Dunstable Regional Middle (grades 5–8), and Groton Dunstable Regional (high school, grades 9–12), enrolling about 2,013 students in total. All belong to the Groton-Dunstable district, which ranks 34th of 351 districts statewide — the 90th percentile — with a 5-star district rating. Notably, that district rating is stronger than any individual school's latest 4-star rating, and all three schools rank at or above the 79th percentile.
Comparing the three, Groton Dunstable Regional is the academic standout: 87th percentile, 75% proficient in math, 69.4% in ELA, 65.63% in science, and 58.82% in Biology, with a 97.5% graduation rate and 0.0% dropout rate. Florence Roche School is the biggest improvement story, rising from the 66th percentile and 3 stars to the 83rd percentile and 4 stars, with 64.68% proficient in math. Groton Dunstable Regional Middle is strongest in science at 62.14%, including 64.97% in 5th grade science and 66.67% in 7th grade math, though its all-grade ELA (51.13%) and math (54.97%) sit below district figures and its percentile slipped from 84 to 79.
Every listed 2025–2026 subject score at every school is above the state average, and the middle school has the lowest student-teacher ratio (12.8) while spending the most per pupil ($18,468); the elementary school has the highest ratio (13.9) and lowest spending ($17,495). Treat those comparisons cautiously — spending is from 2020–2021 and ratios from 2024–2025. Free/reduced-lunch percentages are blank for all three schools, so economic context is simply unavailable rather than a weakness.
