Summary
Charlton Street is a public elementary school in Southbridge, Massachusetts, serving roughly 288 students in grades PK–5 as part of the Southbridge district, which ranks 344th of 351 districts statewide. In 2025–2026, Charlton Street ranked 871st of 899 Massachusetts schools (3rd percentile, 0 stars), and it has sat near the bottom of the state for a decade — 905/906 in 2024–2025 and 915/916 in 2023–2024.
All-grade MCAS Next Generation proficiency in 2025–2026 was 10.69% in English Language Arts, 9.49% in Math, and 5.88% in Science, compared with 17.26%, 15.34%, and 9.47% for the district and roughly 40–41% statewide. Nearby schools post far stronger results: Burgess Elementary ranked 250/899 (72nd percentile, 4 stars) and Holland Elementary ranked 361/899 (60th percentile, 3 stars), while Dudley Elementary, Heritage School, and Old Sturbridge Academy Charter Public School all rank above Charlton Street. Only West Street, in the same district (883/899), is similarly low.
The school's 3rd grade results are its strongest — 22.92% in ELA and 16.67% in Math, both above the district — but proficiency collapses by 5th grade to 1.92% in ELA, 1.96% in Math, and 5.88% in Science, making science a clear weakness. Charlton Street also reported the highest per-student spending among nearby schools ($21,701 in 2020–2021) despite the lowest outcomes, and its student-teacher ratio rose to 13.7 from 10.8 the prior year. Special education effectiveness improved markedly to 508/709 (28th percentile, 1 star), and English language learner results were relatively better at the 13th percentile, but low-income and other student groups remain in the bottom 7% or lower. The 2025–2026 scores are an improvement over the two prior years, yet they remain far below district, state, and nearby-school averages.
