Summary:
ZIP code 45107 serves Blanchester, a small community in southwestern Ohio where all students attend a single district, Blanchester Local, which ranks 281st of 773 Ohio districts (64th percentile, 3 stars). The ZIP contains exactly three schools — Putman Elementary School (PK–3, 471 students), Blanchester Middle School (4–8, 353 students), and Blanchester High School (9–12, 332 students) — totaling 1,156 students, with no charter or alternative options.
Putman Elementary is the clear standout, earning 4 stars and an 83rd-percentile state ranking two years running, up from the 61st percentile in 2022–2023. Its 3rd-grade math proficiency is 80.7% (state 62.1%) and ELA 75.3% (state 63.4%), and it achieves this while serving about 53% economically disadvantaged students. Blanchester Middle is the biggest improver, rising from 2 stars and 47th percentile to 3 stars and 59th percentile, with the lowest chronic absenteeism in the ZIP (13.3%) and 100% proficiency in Algebra I (End of Course) two years straight. Blanchester High has held 3 stars for three consecutive years and reports a 97.9% graduation rate, led by American History at 82.9% and Biology at 72.6%.
Two gaps stand out for parents. First, 7th grade is the middle school's weakest group — math 37.7% (state 48.6%) and ELA 53.6% (state 62.7%) — and it is the same cohort that struggled in 6th grade the year before, suggesting a specific group of students rather than a weak grade-level team. Second, high school Geometry dropped from 51.5% to 43.2%, now essentially level with the state, while high school chronic absenteeism (20.3%) is the highest in the ZIP despite the lowest free/reduced lunch rate (43.37%). Overall, trends diverge: the elementary is flat and excellent, the middle school is climbing, and the high school is drifting slightly downward.
