Summary:
Millis, Massachusetts is a small PK–12 district with just three public schools — one elementary, one middle, and one high school — serving 1,156 students in total. The Millis district ranks 127th of 351 in Massachusetts, placing it at the 64th percentile with 3 stars. Clyde F Brown is the largest school, with about 52% of all enrollment, while the middle and high schools are close in size at roughly 23% and 25%.
Millis Middle is the clear academic standout and the only school with three straight 4-star ratings, landing in the top quartile of Massachusetts middle schools each year (74th, 80th, and 75th percentile). Its 2025–2026 All Grades proficiency was 55.67% in ELA versus 40.03% statewide and 49.47% in math versus 41.11% statewide. Grade-level results are especially strong in 7th grade ELA (66.67%), 8th grade ELA (67.02%), and 8th grade civics (63.44%). The main weakness is 6th grade ELA, at 36.54%, below the state's 40.26%.
Millis High School posts excellent completion outcomes — a 98.7% graduation rate and 1.3% dropout rate — and a very strong Biology End-of-Course result of 56.52% versus 37.68% statewide. However, its 2025–2026 10th grade ELA, math, and science scores fell from the prior year, with science slightly below state, and its ranking slipped from 4 stars to 3 stars (68th percentile). Clyde F Brown shows mixed results: science is above both district and state at 46.34%, and 4th and 5th grade math are above state, but 5th grade ELA (32.53%) and 3rd grade math (34.00%) lag. Note that these schools are small, so year-to-year swings can look dramatic, and spending figures date to 2020–2021 with socioeconomic data unreported, so resource comparisons should be treated cautiously.
