Summary:
Dartmouth, Massachusetts has just one middle school in this data set — Dartmouth Middle — serving grades 6–8 and about 801 students, so parents here have a single option to consider and the most useful comparisons are to the Dartmouth district and the state. The school earned 4 stars in each of the last three ranking years and placed in the 74th to 79th percentile of Massachusetts middle schools. In 2025–26 it ranked 122nd out of 478 schools, while the Dartmouth district overall is rated 3 stars and ranked in the 56th percentile — a sign the middle school is performing above its district's overall profile.
Mathematics is the clearest strength. In 2025–26, all-grades math proficiency was 56.56, compared with 49.56 for the district and 41.11 for the state, and every grade level beat the state by more than 15 points: 6th grade 58.51 vs. 42.59, 7th grade 52.69 vs. 37.48, and 8th grade 58.27 vs. 41.67. English language arts is also solid at every grade level: all-grades ELA was 50, ahead of the district's 45.87 and the state's 40.03. One caution: ELA slipped from 56.51 in 2024–25 to 50 in 2025–26, a 6.51-point decline, though the district also declined.
Science is the relative weak spot. In 2024–25 it was 37.05, below both the district (45.32) and the state (41.51). It improved to 42.05 in 2025–26 — a 5-point gain — but stayed just under the district (42.61) and only modestly above the state (40.98). Civics was 43.31 and then 40, above the district both years. The student-teacher ratio of 10.4 implies roughly 77 teachers for 801 students. Per-student spending of $15,877 comes from 2020–21 and does not match the test-score years, and free/reduced lunch status is not reported, so socioeconomic context is unavailable.
