Summary:
ZIP code 45390 in Union City is home to two schools serving roughly 583 students combined — Mississinawa Valley Elementary School (grades K–6, 307 students) and Mississinawa Valley Junior/Senior High School (grades 7–12, 276 students). Both belong to the Mississinawa Valley Local district and share one campus on Staudt Road, so families here get a complete K–12 experience in a single place. Because each level has just one building, the school results and the district results are identical in this data.
The elementary school is the stronger of the two. In 2025–26 it beat the state in 8 of 9 tested subject areas, including 3rd grade ELA at 82.4% proficient (state: 63.4%), 6th grade ELA at 76.1% (state: 56.0%) and 6th grade Math at 75.6% (state: 56.2%). Only 5th grade Science (50% vs. 62.7%) fell short. It ranks 529th of 1,560 Ohio elementaries — 66th percentile, 3 stars. The high school ranks 420th of 795 — 47th percentile, 2 stars — but posts standout math results: Algebra I at 87.5% (state: 61.6%) and 8th grade Math at 85.1% (state: 52.0%). Its English II (55.9% vs. 62.7%) and Biology (61.8% vs. 67.0%) sit below state. The graduation rate is 95.5%.
Chronic absenteeism runs 14.1% at the elementary and 19.6% at the high school, and the student–teacher ratio is 10.5:1 versus 13.8:1 — the clearest structural differences between them. The elementary slipped from a 4-star year in 2023–24 but has partly recovered; the high school has improved from the 40th to the 47th percentile. With only about 30–45 students per grade, a 20-point year-over-year swing amounts to a handful of students and should be read as a signal, not a firm trend. Free/reduced-lunch data was not available, and spending figures date to 2018–19.
