Summary:
ZIP code 43076 (Thornville, Ohio) contains exactly one middle school — Sheridan Middle School, serving grades 6–8 with 516 students (about 172 per grade) in the Northern Local district — so families in this area have a single middle-school option rather than several schools to compare against one another.
That single option is a solidly above-average one. In 2025-2026, Sheridan scored above Ohio's statewide average in all seven tested subject-and-grade areas, from 8th grade science (74.5% proficient versus 61.2% statewide) down to 8th grade ELA (59.6% versus 58.3%). Math and science are the standout strengths: 7th grade math runs 15.1 points above the state and 8th grade math 14.5 points above. The school is also improving, with six of seven tests gaining year over year and average proficiency up roughly 4.6 points; 6th and 8th grade math each rose about 9 points. Sheridan ranked 334th of 1,046 Ohio middle schools (68th percentile, 3 stars), up from 401st the year before.
The main caution is attendance: 25.9% of Sheridan students were chronically absent in 2025-2026 — roughly one in four — compared with 19.5% across the district, the only measure where the school trails its own benchmark. Its narrowest relative result is 8th grade ELA, just 1.3 points above the state and below it the prior year. Parents should also know that every reported test score here is an exact percentage with none suppressed, but the free/reduced-price lunch figure is unavailable (blank, not zero) and the $9,070 per-student spending figure dates to 2018-2019. Because school and district scores differ by at most 0.4 points, Sheridan effectively enrolls the district's entire middle-grade population.
