Summary:
Dartmouth, Massachusetts, has five schools—three elementary, one middle, and one high school—serving pre-kindergarten through grade 12 in the Dartmouth district, with about 3,205 students enrolled. The district as a whole ranks 153 of 351, at the 56th percentile with 3 stars, but that district number hides large differences among individual schools.
The strongest schools are Dartmouth Middle and Joseph Demello. Dartmouth Middle is the highest-ranked school in the district (122 of 478, 74th percentile, 4 stars) and has been a 4-star school for three years. Its 2025–2026 math proficiency is 56.56, far above the state and district, and its ELA is also strong. Joseph Demello is the top elementary school (252 of 899, 72nd percentile, 4 stars) and outperforms both the district and state in ELA, math, and science, also holding 4 stars for three years.
The other schools show more mixed results. James M. Quinn School is the lowest-ranked school (497 of 899, 45th percentile, 2 stars), having fallen 20 percentile points over two years; its ELA and math are below the district and state, including 3rd-grade math at 20.8. George H Potter is mid-pack (419 of 899, 53rd percentile, 3 stars), above the state but below the district in ELA and math, and has slipped over three years. Dartmouth High (147 of 353, 58th percentile, 3 stars) has strong Biology and science results, but its 2025–2026 grade-10 ELA and math fell below the state after being well above it the prior year. Its 2024–2025 graduation rate was 93.1%.
