Summary:
ZIP code 01550 has three elementary schools, all in the Southbridge district: Eastford Road (PK–1, 397 students), West Street (K–5, 323 students), and Charlton Street (PK–5, 288 students). District context matters here: Southbridge ranks 344th of 351 Massachusetts districts, at the 2nd percentile with 0 stars, and all three schools share that context.
Among the two schools with MCAS results, West Street has the stronger all-grade ELA and math (11% ELA and 6.7% math in 2025–2026) and the better student-teacher ratio (11.1 vs. 13.7), but Charlton Street improved the most year over year — up 6.12 points in ELA, 7.19 in math, and 5.88 in science — and rose in school rank from 915/916 to 871/899. Charlton Street's grade 3 is the brightest spot in the area: 22.92% ELA and 16.67% math, both above the district. West Street's grade 4 ELA and grade 5 ELA and math also beat district averages. Still, both schools are below district averages in every all-grade subject and far below state proficiency near 40%. Science is weak and uneven: West Street was at 16% in 2024–2025, above district, but 4.05% in 2025–2026, while Charlton Street went from 0% to 5.88% — swings likely tied to small grade-5-only cohorts.
Eastford Road has no MCAS results because it serves PK–1 only; that absence of test scores is not a sign of failure. It has the largest enrollment, the lowest per-pupil spending ($17,779), and the highest student-teacher ratio (15.2) of the three. Spending figures are from 2020–2021 while test scores are from 2024–2026, and free/reduced-lunch percentages are blank for all three schools, so no conclusions can be drawn from them.
