Summary:
Middleborough is home to one public high school: Middleborough High, which serves grades 9–12 at 71 East Grove Street and enrolls 774 students. It is the only high school in the Middleborough district, so families in the town have a single local option for secondary education. Its student–teacher ratio of 11.3 to 1 is a structural advantage, implying roughly 68–69 teachers for the building.
In 2024–2025 the school had a genuine standout year. It ranked 135th of 349 statewide (61st percentile, 3 stars) and beat the state in all three core subjects: ELA 53.5% vs. 50.7%, math 48.8% vs. 44.6%, and science 52.5% vs. 45.9%. Its graduation rate, 90.4%, also came in above the district's 88.8%. Even in a weaker year, the high school's ranking (199th of 353, 44th percentile, 2 stars) outpaces the district's overall standing of 28th percentile and 1 star, making this school a relative bright spot within a lower-ranked district.
The most recent year, 2025–2026, brought a broad decline. Tenth-grade proficiency fell double digits in every subject — ELA down 14.1 points, math 12.2, and science 18.4 — steeper than the state's own drops, and the school now trails the state in every assessed subject after leading it a year earlier. The dropout rate, 6.9%, sits slightly above the district's 6.7%, meaning roughly 1 in 14 students exits without completing in a given year. Science is the most volatile measure; biology, assessed separately, held roughly flat and only about 2.6 points below the state. Overall, Middleborough High is a mid-pack school with favorable staffing and an above-district graduation rate, but its proficiency results currently trail the state in every subject.
