ZIP code 01505 in Boylston, Massachusetts, has one high school, Tahanto Regional High, which serves grades 6–12 and enrolls 522 students as part of the Berlin-Boylston district.
For parents, the headline is that Tahanto is consistently one of the strongest schools in Massachusetts. It earned 5 stars in each of the last three reported years, ranking 19 of 353 (95th percentile) in 2025–2026, 28 of 349 (92nd percentile) in 2024–2025, and 22 of 348 (94th percentile) in 2023–2024. The district itself is strong — ranked 59 of 351 (83rd percentile, 4 stars) — but the school’s own rank is higher. In 2025–2026, Tahanto was above the state in every reported subject and grade: 10th-grade ELA 83.1% proficient vs. 45.48% state; 10th-grade math 72.86% vs. 43.73%; 10th-grade science 80% vs. 40.5%; Biology End of Course 71.93% vs. 37.68%; and 8th-grade civics 74.16% vs. 39.77%. All-grades results were also strong: ELA 55.73% vs. 40.03%, math 65.08% vs. 41.11%, and science 68.54% vs. 40.98%.
Graduation and dropout outcomes are very strong: a 98.3% graduation rate and 1.7% dropout rate, with an 11:1 student-teacher ratio. Science improved from 52.5% all grades in 2024–2025 to 68.54% in 2025–2026, moving above the district’s 64.16%. The lowest ELA result, 8th-grade ELA at 49.44%, is still above the state’s 41.70%. In grades 6–8, math generally outperforms ELA; in 10th grade, ELA is stronger than math. Because the school serves grades 6–12, “All Grades” includes middle school, so 10th-grade scores are a cleaner look at high-school performance. Free/reduced-lunch data is blank/unavailable, not 0%, and per-student spending is only reported for 2020–2021 at $16,601, so no recent spending trend can be established.
