Summary:
ZIP code 02478 covers Belmont, Massachusetts, and contains just one public high school: Belmont High, which serves grades 9–12 with 1,454 students and belongs to the Belmont district. Because there is only one high school in this area, there are no in-town peers to compare it against — the meaningful comparisons are between Belmont High, its district, and the state.
Belmont High stands out well beyond its ZIP code. It ranks #4 out of 353 Massachusetts high schools in 2025–2026, placing it in the 99th percentile with 5 stars, up from #6 in each of the two prior years. Its graduation rate is 97.5%, above the district's 96.7%, and its dropout rate is 0.0%. Test proficiency is very high across subjects — generally in the mid-80s to high-80s — while state proficiency on the matching 2025–2026 exams sits in the low-to-mid 40s.
Science is the strongest tested area, at 88.67% proficient in 10th grade, a gap of +48.17 points over the state. ELA is comparatively the lowest at 84.05%, yet still more than 38 points above the state. Math posted the largest year-over-year gain among 10th-grade subjects, rising 3.88 points to 87.00%, while science rose 1.82 points and ELA was nearly flat at +0.20 points; the state declined in all three. Belmont High also edges out the Belmont district in every listed subject. Context metrics include a student-teacher ratio of 15.7 and per-student spending of $15,483 in 2020–2021; the free/reduced lunch percentage is blank in this record, so it should be treated as unknown. Physics data are not perfectly comparable across years (All Grades versus End of Course), so that comparison should be read with caution.
