Summary:
ZIP code 43351 covers Upper Sandusky, Ohio, and contains just one middle school: Upper Sandusky Middle School, a grades 4–8 building with 503 students in the Upper Sandusky Exempted Village district. Because there is only one school here, the meaningful comparison is this school against its own district and the state of Ohio rather than against another local middle school.
On the 2025–2026 Ohio State Tests, that comparison is strongly favorable. The school exceeded the state proficiency rate in all 12 general assessments across mathematics, English language arts and science, by margins ranging from 7.8 to 29.5 percentage points. Math is the engine: an average advantage of 23.4 points over the state versus 13.7 in ELA. Grade 4 math (95.8%) and grade 8 math (81.5%) each run nearly 30 points above the state, and the End-of-Course Algebra I result reached 100% against a state rate of 61.6% — though that figure reflects a small, selected group of advanced students, not all 503. Nine of 13 assessments improved year over year, and the school has climbed Ohio's middle-school rankings three years running, from the 76th to the 81st percentile, holding a 4-star rating throughout.
Watch items for parents: grade 7 is the soft spot, posting the lowest score in the data set (60.7% in math) and the narrowest margins over the state (+12.1 in math, +7.8 in ELA). Science declined at both grades tested. The district also outperforms the school in grades 4–5 ELA, grade 5 math and grade 5 science, suggesting other feeder schools are stronger at the elementary end. The surrounding context is encouraging: chronic absenteeism is 7.3% versus the district's 10.2%, and 49.11% of students qualify for free/reduced lunch.
