Summary:
ZIP code 01550 is served by a single middle school, Southbridge Middle School, which is part of the Southbridge district and serves grades 6–8 with 380 students enrolled. The school reports a student-teacher ratio of 9.2 students per teacher for 2024–25 and per-pupil spending of $19,218 for 2020–21. The free/reduced-lunch percentage is blank for 2024–25, so it should be treated as unknown rather than zero. Because this is the only middle school in the ZIP code, there are no local peers to compare it with — the useful comparisons are to its own district and to the state of Massachusetts.
In 2025–26 MCAS results, the school scored above its district in every reported area but below the state in every subject and grade level. All-grade ELA was 25.20% proficient (district 17.26%, state 40.03%), Math was 24.32% (district 15.34%, state 41.11%), and Science was 14.50% (district 9.47%, state 40.98%). Eighth grade is the strongest band: Math reached 35.11% proficient, the school's best result, and ELA reached 29.01%. Science, at 14.50% proficient, is the largest weakness — 26.48 points below the state — and sixth- and seventh-grade Math are also low, at 18.52% and 18.00%.
There are signs of momentum. From 2024–25 to 2025–26, all-grade Math rose 6.09 points and ELA rose 1.84 points, narrowing the gap to the state. Eighth-grade Civics fell sharply, from 29.85% to 20.45%, though the district fell similarly, suggesting a broader local pattern. The school's rank percentile improved from 19 in 2023–24 to 23 in 2025–26, and it holds 1 star, while the district sits at the 2nd percentile with 0 stars — meaning this school is a relative bright spot within a very low-ranked district, but still below average statewide. Overall, families should see a school with positive momentum and real room to grow.
