Summary:
MSD Decatur Township in Indianapolis has exactly one high school: Decatur Central High School, a large 9–12 campus at 5251 Kentucky Ave enrolling 1,974 students, so the most useful comparisons are against district and state figures rather than other local high schools.
Decatur Central High School's clearest strength is its graduation rate: 91.0% in 2024–2025, above Indiana's 89.7% and matching MSD Decatur Township's 91.0%. Test scores and attendance are the bigger concerns. Chronic absenteeism is 38.4%, versus 24.4% districtwide and 16.7% statewide — roughly 2.3 times the state rate. SAT Math proficiency is 10.02% for 11th graders in 2025–2026, up from 8.13% but far below the state's 25.6%. SAT Evidence-based Reading and Writing rose slightly to 36.4%, still about 15.5 points under the state's 51.9%. Biology ILEARN End-of-Course proficiency improved from 19.63% to 25.35% (+5.72 points), though it remains below the district's 30.32%; no state figure is provided for 2025–2026, and the last available state value was 45.6% in 2024–2025.
The school is rated 1 star in every reported year and ranked 322 of 415 (22nd percentile) in 2025–2026, 346 of 429 (19th) in 2024–2025, and 343 of 432 (21st) in 2023–2024 — slight improvement, but still in the bottom quartile. Context: 56.23% of students qualify for free/reduced lunch, the student-teacher ratio is 15:1, and per-student spending was $11,783 in 2023–2024, with no district or state comparison available. Because it is the only high school, district figures for graduation and SAT mirror the school's exactly, while the higher district Biology proficiency suggests additional data or a different cohort. The practical priorities are attendance intervention and targeted math and science support, while protecting the above-state graduation rate.
