Middle Schools in Holliston

Holliston has a single listed middle school, Robert H. Adams Middle School, which serves grades 6–8 with 626 students and is part of the Holliston district. With only one school, district and school results are closely tied, yet the school itself stands out statewide: it ranked 45th of 478 Massachusetts middle schools in 2025–2026, placing it in the 91st percentile with 5 stars. That is stronger than the district's overall standing of 50th of 351, an 86th percentile, 4-star rating. Recent rank history shows 34th of 493 with 5 stars in 2023–2024, and 51st of 484 with 4 stars in 2024–2025, so the school has returned to a 5-star level.

Proficiency is above both district and state in every reported subject. ELA is 65.11% versus 56.79% district and 40.03% state; mathematics is 69.45% versus 59.00% and 41.11%; science is 68.20% versus 61.89% and 40.98%; and grade 8 civics is 70.09% versus 68.81% and 39.77%. Mathematics is the strongest overall area, and grade 8 is strong across the board: ELA 72.22%, math 75.58%, science 68.20%, and civics 70.09%. Grade 7 is the relative dip, with ELA at 55.62% and math at 57.87% — still above district and state, but well below grade 8 math's 75.58%, suggesting a cohort-level pattern rather than a school-wide weakness.

Year over year, science improved sharply from 63.21% to 68.20%, flipping from 1.50 points below the district to 6.31 points above it. Civics rose 4.52 points and math 2.45 points, while ELA dipped slightly by 0.85 points but remains 25.08 points above the state. Civics is a district-wide strength, so the school's edge over the district there is only 1.28 points. Two caveats: the free/reduced-lunch percentage is not provided, so proficiency cannot be examined alongside socioeconomic need, and per-student spending of $14,279 is from 2020–2021, making it historical context only. The student-teacher ratio of 12.5 is favorable, though no state comparison is given.
