Summary:
ZIP code 02481 contains exactly one public high school: Wellesley Senior High, serving grades 9–12 with 1,262 students in Wellesley, Massachusetts. With only one school in the area, the meaningful comparisons are against its district and the state. It belongs to the Wellesley district, which ranks 5th of 351 Massachusetts districts — the 99th percentile — and holds a 5-star rating. The school also earns 5 stars.
That standing is consistent. In 2025–2026 it ranked 17th of 353 high schools (95th percentile, 5 stars); in 2024–2025, 19th of 349; and in 2023–2024, 16th of 348 — all at the 95th percentile with 5 stars. Completion outcomes are strong: a 96.7% graduation rate in 2024–2025, above the district's 95.3%, and a 0.6% dropout rate, matching the district's 0.6%. MCAS Next Generation proficiency runs far above the state. In 2025–2026, 10th graders reached 77.54% in English Language Arts versus 45.48% statewide, 84.29% in Mathematics versus 43.73%, and 81.41% in Science versus 40.50%; Physics End of Course was 73.97% against 46.58%. The school exceeds its own district by only about +0.12 to +0.81 points in every comparison, showing that it reflects an exceptional district rather than an isolated outlier.
Context and year-over-year movement: the student-teacher ratio was 10.7 in 2024–2025, and per-student spending was $21,475 in 2020–2021 — an earlier-year figure that is context, not a current measure. From 2024–2025 to 2025–2026, 10th-grade ELA rose from 77.13% to 77.54% and Mathematics from 81.03% to 84.29%, while Science fell from 85.52% to 81.41% but stayed far above the state's 40.50%. Physics is not directly comparable across years, since 2025–2026 is End of Course and 2024–2025 is All Grades. Free/reduced lunch is not reported in this extract, so socioeconomic composition cannot be assessed from this data.
