Summary:
ZIP code 02445 is home to a single high school in this dataset: Brookline High, a 5-star school at 115 Greenough Street serving grades 9–12 with 2,181 students in the Brookline district. Because it is the only school here, there is no in-area comparison to make — but against the state, it is among the strongest high schools in Massachusetts. Over the past three years it has ranked 29th of 348 (2023–24), 5th of 349 (2024–25), and 14th of 353 (2025–26), holding 5 stars each year. The 2024–25 year was a clear peak at the 99th percentile; 2025–26 still places it in the top 4% of high schools statewide.
On MCAS Next Generation tests, proficiency runs roughly 32 to 41 percentage points above the state in every subject and both years reported. In 2025–26, 10th-grade Mathematics reached 83.27% and Science 79.03%, with Physics at 79.70%; ELA was the relative internal lag at 77.58%, though still far above the state’s 45.48%. School results are nearly identical to district results — generally within about 1 percentage point — so families can expect the school to track the district’s high performance closely. ELA, Mathematics, and Science all slipped slightly from 2024–25 to 2025–26, but the state slipped too, and the school’s declines were smaller than the district’s.
Completion outcomes are strong: the 2024–25 graduation rate was 96.2%, slightly above the district’s 95.9%, and the dropout rate was 1.6%, matching the district. The student-teacher ratio of 11.8 is favorable, and per-student spending in 2020–21 was $23,558, though no state or peer benchmarks are provided here. Free/reduced-lunch data is blank and should not be read as 0%, which limits any equity analysis. Overall, this is a large, top-tier school with exceptional test performance and solid completion results.
