Summary:
ZIP code 43314 (Caledonia, Ohio) is served by a single public high school, River Valley High School, which enrolls 455 students in grades 9–12 and belongs to the River Valley Local district (ranked 327 of 773, or the 58th percentile, with 3 stars). Because there is only one school here, families should read its results against the state of Ohio and its own prior year rather than against nearby high schools.
Academically, the school performs solidly above the Ohio average in five of six tested End-of-Course subjects in both years on file, with a composite proficiency of about 70.0% in 2025‑2026 versus roughly 63.2% statewide. Social studies is the clear strength: American History (86.9) and American Government (85.0) both run more than 13 points above the state, and History posted the biggest year-over-year gain (+10.2 points). Math is the weak spot. Algebra I (51.4) is the only subject below the state (61.6), and it trails the district by 12.1 points. Geometry (48.4) also sits below the district and slipped 3.4 points, meaning roughly half of tested students are not reaching proficiency in these math courses. English II dropped 4.3 points to 72.0 but remains comfortably above the state.
On non-academic measures, the school reported a 100.0% graduation rate and a 17.0% chronic absenteeism rate — higher than the district's 11.2%, and the largest negative gap in the data. The student–teacher ratio is 18.2 : 1, and the per-student spending figure ($9,043) dates to 2018‑2019, so it should not be read as current. No free/reduced-lunch figure is reported, leaving economic context unknown. Overall: a consistent 3-star, above-state school carried by humanities and social studies, held back by math, with attendance the main risk indicator to watch.
