Schools in Zip Code 45828

ZIP code 45828 covers Coldwater, Ohio, a single-campus town where all three schools — Coldwater Elementary School (K–4), Coldwater Middle School (5–8), and Coldwater High School (9–12) — share one address and enroll about 1,476 students in the Coldwater Exempted Village district, which ranks #69 of 773 Ohio districts (91st percentile, 5 stars).

Coldwater Middle School is the standout: it has earned 5 stars for three straight years, ranks in the top 10% of Ohio middle schools, averages roughly 84% proficiency against a state average of about 57–59%, posted 100% proficiency on Algebra I in both recent years, and has the lowest chronic absenteeism in the ZIP at 1.9%. Coldwater Elementary School is the largest school (667 students) and owns the highest single score in the ZIP — 4th-grade math at 93.3% versus 67.3% statewide — but its rating slipped from 5 stars to 4 in 2025‑26, with 3rd-grade math falling from 87.9% to 78.2% and 4th-grade ELA from 88.0% to 81.5%. Coldwater High School graduates 100% of its students and beats the state in every End-of-Course subject, including Geometry at 78.7% versus 43.3% statewide, but its chronic absenteeism of 9.2% is more than four times the middle school's rate.

Overall, the district outperforms the state in all 21 tested subject areas, with its biggest advantages in math and science and narrower ones in English language arts and history. A few practical notes for parents: the high school reports a free/reduced lunch rate of 68.16%, while the elementary and middle figures are not reported, so no district-wide poverty comparison is possible. The elementary has the highest student/teacher ratio (19:1) and the lowest per-pupil spending ($9,004, from 2018‑19 — historic context only). Enrollment per grade also shrinks from roughly 133 in elementary to about 95 in high school.
