Summary:
ZIP code 02535 is served by a single public school: Chilmark Elementary, an elementary school serving grades K–5 with 69 students, part of the Up-Island Regional district. Because there is only one school in the area, there are no in-ZIP school-to-school comparisons to make; the most useful benchmarks are between Chilmark Elementary, its district, and the state. The district itself ranks 66 of 351 schools, at the 81st percentile with 4 stars.
Chilmark Elementary stands out on performance. Its 2025–2026 statewide rank is 24 of 899 (97th percentile, 5 stars), and its 2024–2025 rank was 12 of 906 (99th percentile, 5 stars). In 2025–2026 MCAS Next Generation results, the school was 35.65 points above the state in English language arts, 26.46 points above in math, and 42.35 points above in science. Science was the strongest subject at 83.33% proficient, compared with 54.84% in the district and 40.98% statewide. Math was solid at 67.57%, with a narrower margin over the district than ELA or science.
Year over year, ELA fell from 83.87% to 75.68% but remains well above both the district and the state, while math was essentially flat, moving from 67.74% to 67.57%. Fifth-grade results in 2025–2026 were especially strong: 83.33% in ELA, 75% in math, and 83.33% in science. With only 69 students and a 6.8 student-teacher ratio, grade-level percentages can swing sharply from year to year. The free/reduced-lunch figure is not reported, so socioeconomic context is unavailable, and per-pupil spending was $31,454 in 2020–2021.
