Summary
Southbridge Middle School is a grades 6–8 school serving 380 students in Southbridge, MA, a small town in south-central Massachusetts, and it sits within the Southbridge district, which ranks near the bottom of the state. The school itself ranked 367th of 478 Massachusetts middle schools in 2025–2026, placing it in the 23rd percentile with 1 star, while the district ranks 344th of 351 — 2nd percentile, 0 stars.
On 2025–2026 MCAS Next Generation tests, 25.2% of students were proficient in English language arts, 24.32% in math, 14.5% in science, and 20.45% in grade 8 civics — below state averages in every subject, but above the Southbridge district average in every subject. Compared with nearby schools, Southbridge Middle posts higher ELA and math proficiency than Webster Middle School, Knox Trail Middle School, and Quaboag Regional Middle Innovation School, and it is close to Oxford Middle in math. However, it trails Sutton Middle School, Auburn Middle, Tantasqua Regional Junior High, Dudley Middle School, and Charlton Middle School by wide margins. Science is the clearest weakness: at 14.5% proficient, it is the lowest science score among these comparison schools — even below Webster.
The school has improved steadily, moving from the 5th percentile statewide in 2018–2019 and 2020–2021 to 23rd in 2025–2026, with ELA and math proficiency also rising. Eighth-grade math, at 35.11% proficient, is a bright spot and above the district's 33.57%. Notably, Southbridge Middle has the lowest student–teacher ratio (9.2) and highest per-student spending ($19,218 in 2020–2021) among nearby schools, yet outcomes remain low — a contrast worth asking about. Subgroup results offer encouragement: English language learners rank at the 58th percentile (3 stars), low-income students at the 39th percentile, and special education students at the 24th percentile, up from 13th in 2023–2024.
