Summary:
Decatur, Indiana has one public high school serving grades 9–12: Bellmont Senior High School, a 613-student campus in the North Adams Community Schools district. Because it is the only high school listed for the area, parents are comparing it against its district, the state, and its own prior years rather than against a neighboring Decatur high school.
Bellmont stands out on the numbers. It is a 4-star school ranked 57th of 415 Indiana high schools in 2025–2026, placing it in the 86th percentile, and that standing has held steady for three years (57th of 415, 56th of 429, and 55th of 432, all 4 stars). The district overall sits at 100th of 374, or the 73rd percentile, so the high school ranks notably higher than the district as a whole. Graduation is 92.6%, above Indiana's 89.7%, and chronic absenteeism is 14.2%, below the state's 16.7% though slightly above the district's 13.5%. Test results are strong versus the state: SAT Math proficiency is 36.67% against 25.6% statewide, and Biology rose from 48.63% to 58.33%. SAT Evidence-based Reading and Writing slipped from 69.33% to 58%, still above the state's 51.9%.
School and district test scores and graduation rates are identical, which likely reflects Bellmont being the district's only high school. About 32.46% of students qualify for free or reduced lunch, the student-teacher ratio is 12.6, and per-student spending is $14,989 for 2023–2024; the file offers no state averages for those, so they cannot be judged as high or low. The 2025–2026 Biology state figure is not listed and should be treated as unavailable. Overall, this is a consistently high-ranked, 4-star school whose main watch point is the decline in SAT Reading and Writing.
