Summary:
ZIP code 01886 (Westford, Massachusetts) is home to two public middle schools — Stony Brook School and Blanchard Middle — both serving grades 6–8 and both part of the Westford district. Their enrollments are nearly identical, at 546 and 541 students. The district as a whole ranks 38 of 351 statewide (89th percentile, 4 stars), and each school scores well above Massachusetts proficiency levels in every reported subject and year.
Stony Brook School is the math standout. Its all-grade math proficiency of 74.33% beats Blanchard's 67.17%, the district's 66.62%, and the state's 41.11%, and it leads Blanchard by 12.83 points in 6th-grade math. Its 8th-grade math score of 76.27% is the highest current grade-level score in the data. Stony Brook also holds the stronger current rank — 48 of 478, 90th percentile, 5 stars — and has kept 5 stars across three years (29th, then 39th, then 48th). Its weaker spot is science, at 68.93%, slightly below the district and behind Blanchard.
Blanchard Middle is the science leader at 71.60%, above Stony Brook and the district, and it posted the stronger historical rank peak: 17 of 493 (97th percentile, 5 stars) in 2023–2024, then 29 of 484, before slipping to 58 of 478 (88th percentile, 4 stars). Blanchard's 8th-grade civics of 78.31% in 2024–2025 was exceptional, but it fell to 67.86%, nearly tying Stony Brook's 67.22%. All-grade ELA is essentially tied. Both schools declined in ELA and math year-over-year, though Stony Brook's math drop was smaller. Blanchard has a slightly lower student-teacher ratio (12.0 vs. 12.9) and slightly higher per-pupil spending ($15,857 vs. $15,678), but free/reduced-lunch data is suppressed for both and spending is from 2020–2021, so those figures are context only.
