Summary:
ZIP code 01720 is served by a single public high school, Acton-Boxborough Regional High, which enrolls 1,622 students in grades 9–12 at 36 Charter Rd in Acton, Massachusetts, and belongs to the Acton-Boxborough district. Because it is the only high school in the area, the most useful comparisons are to the district, the state, and the school's own history — and by those measures, it is a standout. The district itself ranks 44 of 351 statewide (87th percentile, 4 stars), while the high school's own rank history is even stronger: 6th of 353 (98th percentile, 5 stars) in 2025–26, 13th of 349 (96th percentile, 5 stars) in 2024–25, and 7th of 348 (98th percentile, 5 stars) in 2023–24. That places it consistently in roughly the top 2–4% of Massachusetts high schools.
Test results are far above state averages. In 2025–26 MCAS Next Generation results, 10th graders scored 86.2% in English Language Arts, 85.25% in Mathematics, and 82.29% in Science, with Biology end-of-course at 80.37% — roughly 40–43 percentage points above the state in every reported subject. The school also edged out its district in each subject, though the gaps were small (under 1 percentage point), which suggests the whole district performs at a high level and the high school sits right at or slightly above that mark. From 2024–25 to 2025–26, 10th grade scores rose in ELA (+3.04 points), Math (+2.56), and Science (+3.19) while state scores declined, widening the school's advantage. ELA and Math were consistently the strongest subjects, with Biology lowest — though still far above the state.
Outcomes beyond testing are strong as well. The 2024–25 graduation rate was 96.4% versus the district's 94.4%, and the dropout rate was 1.5% versus 2.0%. Other context: a student-teacher ratio of 13.4 in 2024–25 and per-student spending of $17,610 in 2020–21, though the dataset offers no state or district benchmarks for those two figures. Free/reduced lunch data is not available, so socioeconomic context cannot be assessed.
