Its rank history is steady, ranging from the 32nd to 34th percentile with 2 stars each year. Monson High School trails it: all-grade ELA was 18.55% and science 23.21%, both below the district, with math at 28.1% essentially even with the district. Its rank has slid from the 49th percentile in 2023–2024 to the 41st and then the 34th in 2025–2026. The clearest weak spot is 8th grade civics at 12.73%, a 27.04-point gap below the state's 39.77%.

Quarry Hill Community School serves PK–K, so it has no test scores or rank history; it has the highest per-student spending at $21,781. Granite Valley spends the least ($18,256) yet posts the strongest tested results, while Monson High has the smallest student-teacher ratio (8.1) but generally lower proficiency — comparisons that are suggestive, not causal. Free/reduced-lunch percentages are blank for all three schools, and spending figures are from 2020–2021 while test and rank data run through 2025–2026.
