Summary:
Miamisburg City, Ohio is home to a single middle school — Miamisburg Middle School — which serves grades 6–8 with an enrollment of 1,105 students, so the most useful comparisons for families are between this school and the state, the Miamisburg City district overall, and the school's own results from year to year.
Miamisburg Middle School's clearest strength is English language arts, where every tested grade level beat the state average in both 2024-25 and 2025-26. Seventh grade ELA reached 71.0% proficient in 2025-26, which is 8.3 points above the state's 62.7%. The school's Algebra I End-of-Course result is even more striking at 97.7% proficient, compared with 61.6% statewide, though middle-school Algebra I is generally taken by advanced students, so it should not be read as a reflection of the whole school. Math elsewhere is mixed: seventh grade math at 57.6% is 9.0 points above the state, but sixth grade math (48.7%) and eighth grade math (39.4%) are 7.5 and 12.6 points below it. Eighth grade math is the most persistent gap, sitting more than 12 points under the state in both years, even though it improved 4.3 points year over year. Chronic absenteeism is 24.0%, above the district's 21.4%. In state ranking, the school has held steady at 3 stars and roughly the 52nd–54th percentile, while the district earns 2 stars at 48th percentile. Just over half of students (52.31%) qualify for free or reduced-price lunch, the student-teacher ratio is 15.3, and per-student spending of $9,438 dates from 2018-19. Overall, this is a stable, above-district school with strong reading results and a math gap to watch.
