Summary:
Monson, MA is home to two elementary schools that serve different parts of the early grades: Granite Valley School, which covers grades 1–6 with about 400 students, and Quarry Hill Community School, which serves pre-kindergarten and kindergarten with about 120 students. Both belong to the Monson district, which is ranked 286 out of 351 Massachusetts districts — the 19th percentile, with 1 star. Combined, the two schools list roughly 520 students.
Granite Valley School is the only one of the two with MCAS results, and it is the stronger academic performer within the district. In both reported years, its all-grade scores beat Monson district averages in ELA, math, and science, yet it stayed below state averages in all three. Science is its strongest relative subject — 38.24 in 2025–2026 against a state mark of 40.98, a gap under 3 points. Math is the biggest concern: all-grade math was 30.16, about 11 points under the state, with 4th-grade math at 22.95 versus 43.2 statewide and 5th-grade math at 23.53 versus 39.5. Bright spots include 6th-grade math at 40.32, only 2.27 points below state, and 3rd-grade ELA at 39.34, just 3.45 points below state. Its school rank has held steady around the 32nd–34th percentile with 2 stars for three years.
Quarry Hill Community School stands out on non-test measures: per-pupil spending of $21,781 in 2020–2021, about 19.3% more than Granite Valley's $18,256, and a slightly lower student-teacher ratio of 11.8 versus 12.1. Because it serves PK–K, it has no MCAS data and cannot be academically compared to Granite Valley. Free/reduced-lunch figures are not reported for either school, and spending data is from 2020–2021, so spending-to-outcome comparisons should be made cautiously.
