Summary:
Monson, Massachusetts has one public high school, Monson High School, a combined grades 7–12 school with 280 students, so parents should compare it mainly with the Monson district and state averages rather than with other local high schools. It ranks 232 of 353 (34th percentile, 2 stars) in 2025–26, while the district ranks 286 of 351 (19th percentile, 1 star). The school’s rank percentile has declined from 49 in 2023–24 to 41 in 2024–25 to 34 in 2025–26, though it kept 2 stars each year. Graduation is 80.0% and dropout is 6.7%, identical to the district. Student–teacher ratio is 8.1 and per-student spending was $19,374 in 2020–21; free/reduced-lunch data is unavailable.
On 2025–26 MCAS, 10th grade is stronger than the all-grade totals: ELA is 38.89% proficient versus 18.55% for all grades, math is 31.43%, and science is 25%. Those 10th-grade results roughly match the district but trail the state (45.48% ELA, 43.73% math, 40.5% science). Eighth-grade math is a relative bright spot at 35.71%, above the district’s 34.48% and close to the state’s 41.67%. Eighth-grade civics is the sharpest weakness: 12.73% versus 12.28% district and 39.77% state, down from 23.08% in 2024–25. Middle-school ELA is also low: 7th grade 19.12% and 8th grade 17.86%, compared with state rates of 39.91% and 41.7%.
Year-over-year changes are unusually large. All-grade ELA fell from 32.54% to 18.55%, while the district fell about 5.7 points and the state about 1.5 points. All-grade math rose from 12.8% to 28.1%, while the district rose about 4 points and the state barely changed. These swings may reflect cohort effects or small grade sizes. Overall, Monson High School is a small combined school with a low student–teacher ratio and high per-student spending, but outcomes are mixed: 10th-grade results and 8th-grade math are relatively stronger, while 8th-grade civics and middle-school ELA are major weaknesses, and the multi-year rank decline is notable. Missing free/reduced-lunch data limits context.
