Summary:
ZIP code 45331 in Greenville, Ohio is served by three public schools — Greenville Elementary School (grades K–4, 788 students), Greenville Middle School (grades 5–8, 658 students), and Greenville Senior High School (grades 9–12, 776 students), all part of the Greenville City district, which enrolls 2,222 students across these buildings and ranks 482 of 773 Ohio districts (38th percentile, 2 stars).
Greenville Middle School is the strongest of the three, holding 3 stars and the 50th percentile in both 2025–2026 and 2024–2025, with the lowest chronic absenteeism at 17.0% (below the district's 20.8%). Its Algebra I results are exceptional at 100% proficient in 2025–2026 and 98% the year before. Greenville Elementary School has been stable at 2 stars and roughly the 45th percentile, with above-state 4th grade math and improving 3rd grade ELA (68.3%), but persistent weakness in 4th grade ELA. Greenville Senior High School graduates 97.3% of students — the highest rate here — yet its rank fell from the 55th to the 35th percentile over three years, and it has the highest absenteeism at 26.9%.
Two patterns cut across all three schools. English Language Arts is the shared weak spot: elementary 4th grade ELA and high school English II trail the state in both years, and middle school ELA is below state in every tested grade in 2025–2026. Math is more mixed, with strong elementary 4th grade math, solid middle school Algebra I, 6th and 8th grade math, improving high school Algebra I, but a clear high school Geometry gap (30.3% vs. the state's 43.3%). Economic need is highest at the elementary level (68.65% free/reduced lunch) and lowest at the high school (51.16%), and per-student spending follows the same pattern ($9,783 vs. $8,266 in 2018–2019).
