Summary:
ZIP code 44621 (Dennison, Ohio) is home to exactly one school — Claymont Intermediate School, a grades 3–5 building with 341 students in the Claymont City district. Because it is the only school in this ZIP, there is no cross-school comparison to make; instead, the useful picture comes from how this school performs against the state and over time.
In 2025-2026, the school's proficiency averaged 52.0% across seven tests, about 11.8 points below the state average of 63.8% — a wider gap than the prior year's 5.8 points. Third-grade English language arts is the most persistent weak spot, at 45.2% this year and 42.7% the year before, roughly 16–19 points below the state both years. Fifth-grade math also swung sharply: it was 66.3%, or 9.6 points above the state in 2024-2025, then fell to 52.9%, 6.2 points below the state, in 2025-2026. On the positive side, 4th-grade math (58.1%) is the school's narrowest gap to the state this year at −9.2 points, and last year's 5th-grade ELA matched the state exactly at 67.7%. Following the same students forward, the younger cohort improved in both math (52.4% to 58.1%) and ELA (42.7% to 45.3%).
Attendance is the clearest strength: chronic absenteeism is 14.5%, which is 3.2 points better than the district's 17.7%. The school's state ranking has slipped from the 42nd to the 38th to the 31st percentile over three years, though its 2-star rating has not changed, suggesting the star band is too coarse to capture that slide. Two caveats matter for parents: the per-student spending figure ($9,555) is from 2018-2019 and is not comparable to current results, and the free/reduced-lunch figure is unavailable, so no poverty context can be given. With roughly 110 students per grade, small year-to-year swings can reflect only a handful of children; the gap to the state is the steadier signal.
