Summary

Waterloo High School in Atwater, Ohio, is a small public high school serving grades 9–12 in the Waterloo Local district, with 203 students. In 2025–2026 it ranked 297th of 795 Ohio high schools — 63rd percentile, 3 stars — while the district ranked 443rd of 773, 43rd percentile, 2 stars. That gap suggests the high school is a relative strength within its district. The school has moved between 2 and 4 stars over the past decade, peaking at 80th percentile, 4 stars in 2022–2023.

Test results are above state averages in most subjects. Geometry is the standout: 64.5% proficient versus a state average of 43.3%, second only to Lake Middle / High School among nearby schools. English II is also second locally at 75.0%, behind Lake's 88.0%. American History, Biology, and American Government all beat the state as well. Algebra I is the exception — 58.1%, below both the state (61.6%) and the district (67.3%) — and it was below state in 2024–2025 too. One notable bright spot: the Low Socio Economic Status subgroup ranked 99th of 761, or 87th percentile, 4 stars, stronger than the school's overall result.

Graduation is a success story: the rate climbed from 84.4% in 2022–2023 to 96.9% in 2025–2026, near the top of the nearby group. Chronic absenteeism, though, is 33.0%, above the district's 24.0% and higher than most nearby schools. Class sizes are small — an 11.2 student-teacher ratio, lower than almost every nearby school, including Marlington High School at 17.8 — and about 47.78% of students receive free/reduced lunch. Per-student spending was $9,407 in 2018–2019, mid-pack locally.
