Summary:
ZIP code 01746 has one middle school, Robert H. Adams Middle School, serving grades 6–8 in Holliston, Massachusetts, with 626 students in the Holliston school district; because it is the only middle school in the ZIP code, this is a detailed look at one school rather than a comparison among several.
The school is a consistent top-decile performer among Massachusetts middle schools. It ranked in the 91st percentile in 2025–2026, the 89th percentile in 2024–2025, and the 93rd percentile in 2023–2024, roughly the top 7–11% each year, and earned 5 stars in 2023–2024 and 2025–2026 and 4 stars in 2024–2025. In 2025–2026, proficiency was 65.11% in ELA, 69.45% in mathematics, 68.20% in science, and 70.09% in civics, while state proficiency in those subjects was around 40%. Grade 8 was especially strong, with 72.22% in ELA and 75.58% in mathematics, both the highest reported grade-level results. Grade 7 was lower, at 55.62% in ELA and 57.87% in mathematics, but still well above state averages. Year over year, mathematics rose 2.45 points, science rose 4.99 points, and civics rose 4.52 points, while ELA slipped 0.85 points. Science also moved from slightly below the district to above it.
Context matters: the Holliston district is also high-performing, ranked 50 out of 351 districts at the 86th percentile with 4 stars, so the school is excelling within a strong district. The student-teacher ratio was 12.5 in 2024–2025, per-student spending was $14,279 in 2020–2021, and free/reduced lunch data was not reported. For parents, the main strengths are consistently top-decile rankings and proficiency far above the state in every reported subject. The main things to watch are the relatively lower Grade 7 results and the slight ELA decline. Missing lunch data and outdated spending figures leave some context unanswered.
