Summary:
ZIP code 43155, which covers Sugar Grove, Ohio, contains exactly one public high school: Berne Union High School, a grades 7–12 building serving about 366 students as part of the Berne Union Local district. Because there is only one school here, there is no local peer to compare it against — the useful benchmark is the state of Ohio. It is also the district's only high school, so school and district figures are often identical. Since the school covers grades 7 through 12, its test results mix middle-school exams with high school End-of-Course tests, and the 7th and 8th grade scores come from a different group of students each year.
On the 2025–26 state tests, the school outperformed Ohio on ten of eleven subjects, averaging roughly 65.5% proficient against about 60.2% statewide. Its strongest results were English II (73.8%), 7th grade ELA (76.6%) and 7th grade math (60.9%), each well above the state. Eight of eleven subjects improved over the previous year, with the largest gains in English II (+18.9 points), 8th grade math (+17.6) and 8th grade ELA (+15.8) — the subjects that had previously fallen below the state. Two soft spots remain: 8th grade science, the only subject below the state in 2025–26 and also below it the year before, and Geometry, where 44.8% proficient is the lowest result at the school, though still slightly above the state.
These results come in a high-poverty setting, with 92.62% of students eligible for free or reduced lunch. The graduation rate is 98.6%. Chronic absenteeism is 16.3% at the school versus 14.8% district-wide — roughly one in six students — which is worth watching as an early signal for future performance. The school's state rating rose from 2 stars (42nd percentile) to 3 stars (53rd percentile), recovering much of the ground lost the prior year, although the district as a whole ranks in the 63rd percentile.
