Summary
Holliston High is a public high school in the suburban town of Holliston, Massachusetts, serving 809 students in grades 9–12 and ranking 30th of 353 Massachusetts high schools in 2025–2026 (92nd percentile, 5 stars). That places it above its own Holliston district, which ranks 50th of 351 districts statewide (86th percentile, 4 stars). After sitting in the 50s–60s from 2021–2022 through 2023–2024, the school improved to 38th in 2024–2025 and 30th in 2025–2026 — a clear upward trend, though it was 13th back in 2020–2021.
Academically, Holliston's 2025–2026 10th-grade MCAS results are far above the state in every core subject. Math is the standout at 81.68% proficient (state: 43.73%), essentially tied with Medfield Senior High and behind only Dover-Sherborn Regional High and Hopkinton High. ELA comes in at 73.44% and Science at 72.97%, both strong but behind those same three schools. Biology is the relative soft spot at 63.11% — still above state, but below several nearby peers. Locally, Holliston is upper-tier: it trails only Dover-Sherborn, Hopkinton, and Medfield, and clearly outpaces Natick High, Ashland High, Medway High, Millis High School, Hopedale Junior Senior High, Joseph P Keefe Technical High School, and Milford High.
Graduation and dropout outcomes are strong: a 96.1% graduation rate and 1.0% dropout rate in 2024–2025, better than Medway, Ashland, Hopedale, Natick, Keefe Tech, and Milford, though behind Dover-Sherborn, Millis, Medfield, and Hopkinton. The student–teacher ratio is 12.4, mid-pack locally. Notably, per-pupil spending was $14,596 in 2020–2021 — lower than most nearby districts — while results remain top-four locally, an efficiency signal worth noting, though the spending figures are dated. Special education students rank at the 91st percentile, up sharply from the 61st two years earlier; low-income students rank at the 76th percentile, and a few smaller student groups rank lower, at the 65th–67th percentiles, indicating relative opportunity gaps despite strong overall performance.
