Summary

Chelmsford High is the town of Chelmsford's only comprehensive high school, serving about 1,400 students in grades 9 through 12 in the suburban area northwest of Lowell, and it is a consistently strong performer. It ranks 48th out of 353 Massachusetts high schools — the 86th percentile — and has earned four stars for ten consecutive years, never dropping below the 77th percentile or rising above the 88th. It also outperforms its own district, Chelmsford, which suggests the high school is the district's strongest asset rather than a drag on it.

On the 2025–2026 Grade 10 MCAS, 68.5% of students were proficient in English language arts, 66.2% in math, and 62.4% in science, against statewide rates of 45.5%, 43.7%, and 40.5% — roughly 22 points higher in every subject. The four-year graduation rate is 98.8% and the dropout rate is 0.9%. Among nearby schools, only Westford Academy (99.2% graduation) and Gr Lowell Regional Vocational Technical (98.6%) are in the same bracket. Chelmsford's graduation rate is 15.7 points above Lowell High's 83.1%, and it far outpaces Tyngsborough High School and Dracut Senior High.

What stands out most is how evenly the school serves its students: low-income students and students receiving special education services rank at or above the school's overall standing — unusual, and a strong sign of effective instruction. The main watch item is literacy, where proficiency has fallen from 83.2% to 68.5% over two years; the state declined as well, but Chelmsford's lead has narrowed slightly. Math and science dipped in 2024–2025 and have since rebounded. The regional benchmark ahead of it remains Westford Academy, which posts higher proficiency in every subject while spending about $1,900 less per student.
