Summary:
ZIP code 01550 contains six schools with a combined enrollment of roughly 1,828 students: three elementary schools, one middle school and two high schools, all operated by the Southbridge district. That district ranks 344 of 351 in Massachusetts, at the 2nd percentile with 0 stars, so most local results sit below state averages and the most useful comparisons are usually between the schools themselves.
Southbridge Middle School is the clearest standout. It is the only school in the ZIP with a star, ranking 367 of 478 at the 23rd percentile, and it beats the district average in ELA, math, science and civics. Its 8th grade math result of 35.11 comes closest to the state's 41.67 among local schools, though it is still below state level. Southbridge High School, the largest school at 419 students, graduates 80.5% of students — above the district's 78.6% — but its 10th grade proficiency sits in the 7–9% range. Southbridge Academy, with just 21 students in grades 6–12, spends the most per student at $43,714 yet has the lowest graduation rate (70.0%) and highest dropout rate (20.0%).
West Street (883 of 899, 2nd percentile) and Charlton Street (871 of 899, 3rd percentile) rank lowest among schools with rank data, while Eastford Road serves only PK–1 and has no test scores. Science is weak throughout: Charlton Street's 2024–2025 science result was an exact 0% proficient, and 2025–2026 science figures range from 4.05 to 14.5. Spending does not track outcomes in a simple way. Free/reduced-lunch data are blank for every school, and spending figures are from 2020–2021 while achievement data cover 2024–2026, so conclusions should stay cautious.
