Summary:
ZIP code 01450 (Groton, Massachusetts) contains exactly one public elementary school: Florence Roche School, a K–4 building at 342 Main Street with 615 students and a student–teacher ratio of 13.9. It belongs to the Groton-Dunstable district, which ranks 34th of 351 Massachusetts districts (90th percentile, 5 stars). With no in-ZIP peer to compare against, the useful yardsticks are the district, the state, and the school's own track record.
Achievement is well above state norms. School-wide, 64.68% of students were proficient in math versus 41.11% statewide and 59.29% in the district; in ELA, 55.78% were proficient versus 40.03% statewide and 53.56% in the district. Every reported subject-grade result sits between 14 and nearly 24 points above the state average, and math leads ELA by 8.9 points — a far wider gap than the under-1.5-point gap seen statewide. One nuance worth knowing: at the All-Grades level the school outpaces its district in both subjects, but in all four reported grade-level cells (Grades 3 and 4) it trails the district by roughly 2.6 to 4.5 points, since district figures span tested grades beyond this K–4 building.
The school's trajectory is upward: it ranked 310th of 916 schools (3 stars) in 2023–2024, 176th of 906 (4 stars) in 2024–2025, and 151st of 899 (4 stars, 83rd percentile) in 2025–2026. Math proficiency rose 2.13 points year over year while ELA slipped 1.88 points, close to the state's own 1.50-point drift. Fourth-grade ELA, at 51.45%, is the clear soft spot — the lowest reported figure for the school and about 15 points below the state average. Two context gaps limit any fairness judgment: the free/reduced-lunch percentage is not reported, and the $17,495 per-pupil spending figure dates from 2020–2021.
