Summary

Cohasset High School is a small public high school in Cohasset, Massachusetts, serving grades 9–12 with 381 students; it is part of the Cohasset district, which ranks 24th of 351 districts statewide (93rd percentile, 5 stars). The school ranked 42nd of 353 high schools in 2025–2026 (88th percentile, 4 stars), a step down from 18th place (95th percentile, 5 stars) in 2024–2025, but it has finished in the top decile in most of the past decade.

Test scores remain well above state averages: 2025–2026 10th graders scored 75.31 in English language arts, 74.07 in math, and 56.96 in science, each far above the state, while physics stood out at 76.14 — the highest among nearby schools reporting it. Still, Norwell High and Hingham High posted higher ELA, math, and general science scores and edged ahead in the 2025–2026 rankings, though Cohasset High School outranked both the year before. Completion outcomes are elite: a 99.0% graduation rate and 0.0% dropout rate, essentially tied with Norwell for best locally and far ahead of Rockland Senior High (87.5% graduation, 10.3% dropout) and Weymouth High School (90.8%, 5.8%).

Cohasset combines strong results with favorable resources. Its 2024–2025 student-teacher ratio of 8.9 is the second-lowest nearby, just above Hull High (8.8) and far below Hanover High (13.2) and Hingham High (12.8), and per-student spending was $20,326 in 2020–2021, third-highest locally. Effectiveness for special education students has climbed from the 82nd percentile in 2023–2024 to the 92nd in 2025–2026, and results for male students remain consistently strong, while some other subgroup rankings have fluctuated. With 381 students — smaller than every nearby high school except Hull — Cohasset offers a close-knit setting, though Norwell and Hingham achieve similar results with lower reported spending, so resources are only part of the picture.

Open Quote The students within this school are not only homophobic but indirectly racist towards anyone who is not a melaninly lacking person. They're rude, disrespectful and full of themselves. Close Quote
