Summary:
ZIP code 45342 is home to a single middle school, Miamisburg Middle School, which serves grades 6–8 and enrolls 1,105 students — roughly 365 to 370 per grade level, making it a large middle school. It belongs to the Miamisburg City district, which is rated 2 stars and sits at the 48th percentile (rank 402 of 773), while the school itself earns 3 stars and ranks 482 of 1,046 Ohio middle schools at the 54th percentile. In short, the school is outperforming its own district's overall profile and has held steady at 3 stars and the 52nd–54th percentile for three straight years.
Test results are sharply split by subject. Algebra I is the standout: 97.7% proficient in 2025–26 and 100% in 2024–25, against state rates of 61.6% and 59.4% — about 36 points above the state. That result likely reflects a small, self-selected accelerated cohort rather than all 8th graders. Reading is the school's genuine, caveat-free strength: every ELA measurement in both years is at or above the state, with 7th-grade ELA at 71% (state 62.7%). Math is more uneven. Seventh-grade math beats the state by 9 points (57.6% vs. 48.6%), but 8th-grade math trails by roughly 12.6 points (39.4% vs. 52%) and 6th-grade math by 7.5 points (48.7% vs. 56.2%) — a pattern that has repeated for two years straight, suggesting an issue at the entry and exit grades rather than school-wide.
Overall, the school improved modestly: averaging its seven non-Algebra tests, it moved from 54.1 (slightly behind the state's 54.9) to 56.7 (slightly ahead of the state's 56.4), with six of eight tests improving. Roughly half the student body is economically disadvantaged (52.31% free/reduced lunch), and chronic absenteeism is 24.0% — 2.6 points worse than the district's 21.4%, or about one in four students. The only spending figure available, $9,438 per pupil, dates to 2018–19 and is too old to draw current conclusions from.
