Summary:
There is one public high school in Wilmington, Massachusetts: Wilmington High, which serves grades 9–12 and enrolls 619 students. It belongs to the Wilmington district, which is ranked 76th of 351 districts in the state. Because it is the only high school in the area, there are no in-town school-to-school comparisons to make — the useful benchmarks are the school against its district, against the state, and against its own past performance.
Wilmington High is a 4-star school ranked 88th of 353 high schools statewide in 2025–2026, placing it in the top quarter of Massachusetts high schools. Its graduation rate is 95.9%, above the Wilmington district's 93.4%, and its dropout rate is a low 1.4%. On MCAS Next Generation tests, the school's proficiency rates exceed the state in every reported subject and year — by about 9.7 points in 10th-grade English Language Arts and by 15.3 points in Biology, its largest advantage. It also beats the district in every subject, though by smaller margins of roughly 1 to 2.5 points, which suggests the district as a whole performs well and the high school adds a modest extra edge. Mathematics, Science, and Biology show the biggest statewide advantages.
Two items are worth watching. First, the school's state rank has slipped from 61st in 2023–2024 to 85th and then 88th, with its percentile falling from 82 to 75, although it has held 4 stars throughout. Second, 10th-grade ELA proficiency dropped from 60.58% to 55.21% and Science from 61.11% to 52.56% between 2024–2025 and 2025–2026 — but the district saw similar declines, so this looks more like a district-wide or cohort pattern than a school-specific problem. Some context data, including free/reduced lunch status, is not reported, which limits how far comparisons can be pushed.
