Summary:
ZIP code 02346 is served by a single public high school: Middleborough High, which enrolls 774 students in grades 9–12 as part of the Middleborough district. Because it is the only high school in the area, families here have one option for grades 9–12, and the most useful comparisons are against the district, the state, and the school's own past years rather than against nearby schools. The school has a student-teacher ratio of 11.3 and per-student spending of $15,982, though that spending figure is from 2020–2021 and is older than the latest test and ranking data. The free/reduced lunch percentage is blank in the data, so it should not be read as 0%.
Middleborough High's results have been volatile. Its ranking went from the 47th percentile in 2023–2024 to the 61st percentile in 2024–2025 (135 out of 349 schools, 3 stars), then fell to the 44th percentile in 2025–2026 (199 out of 353 schools, 2 stars). In 2024–2025 the school was above the state in all three reported 10th-grade subjects — ELA at 53.53% proficient, math at 48.81%, and science at 52.53%. In 2025–2026 it fell below the state in every reported subject: ELA at 39.43% versus 45.48% statewide, math at 36.57% versus 43.73%, and science at 34.15% versus 40.50%. Science showed the largest year-over-year decline, down 18.38 percentage points.
Those declines appear to be district-wide: Middleborough district scores fell by nearly identical amounts in ELA and math, and by an even larger 18.97 points in science, while state science fell 5.39 points. In 2025–2026 the school scored above its district but below the state in every reported subject, and the district itself ranks 253 out of 351 (28th percentile, 1 star). For 2024–2025, the school's graduation rate was 90.4%, above the district's 88.8%, while its dropout rate of 6.9% was slightly above the district's 6.7%; no state comparison was provided for those two measures.
