Summary

Stony Brook School is a public middle school at 9 Farmer Way in Westford, Massachusetts, serving 546 students in grades 6 through 8 as one of two middle schools in the Westford district.

Stony Brook ranks 48th of 478 Massachusetts middle schools — the 90th percentile — and has earned five stars for ten consecutive years, never falling outside the top 10% statewide. No nearby school matches that record: Blanchard Middle, Littleton Middle School, and Groton Dunstable Regional Middle are all currently rated four stars. Math is the school's signature strength. Its 74.33% math proficiency is the highest of the ten nearby middle schools compared and sits 7.2 points above Blanchard Middle (67.17%), while the two schools are essentially tied in English language arts (60.64 vs. 60.23). Blanchard Middle leads in science (71.60 vs. 68.93), so families choosing between Westford's two middle schools are picking between a math-leaning school and a science-leaning one. Stony Brook also beats its own district average in math at every grade level.

Its most striking equity result: low-income students rank in the 95th percentile of schools statewide — higher than the school's own 90th percentile — a pattern sustained for three years, and special education students rank in the 88th percentile. Class size (12.9 students per teacher) and per-pupil spending ($15,678) are ordinary for the area, so results are not explained by smaller classes or extra money. English language arts is the soft spot: 7th grade ELA (56%) fell below the district average, part of a district-wide decline.
