Summary:
South Dearborn Community School Corp in Aurora, Indiana, operates a single high school — South Dearborn High School — serving grades 9–12 with 625 students. The district is ranked 154th of 374 Indiana districts (59th percentile, 3 stars). Because there is only one high school, its results effectively define the district's high school outcomes: district SAT and graduation figures match the school's exactly, while the district's lower chronic absenteeism rate of 14.1% versus the school's 24.1% likely reflects the inclusion of other grade levels rather than a different high school result.
South Dearborn High School's clearest strengths are graduation and reading. Its 2024–2025 graduation rate of 93.7% is 4.0 percentage points above the state's 89.7%. In 2025–2026, 54.14% of students were proficient in SAT Evidence-based Reading and Writing, above the state's 51.9%. The school is also rising in state rankings, moving from 206th of 432 (52nd percentile) in 2023–2024 to 195th of 429 in 2024–2025 and then 131st of 415 (68th percentile) in 2025–2026 — roughly the top third of ranked Indiana high schools — while holding 3 stars throughout.
Two areas need attention. Chronic absenteeism was 24.1% in 2024–2025 — 10.0 points above the district and 7.4 points above the state's 16.7% — the school's most obvious risk indicator. SAT Mathematics proficiency was 23.57% in 2025–2026, below the state's 25.6%, though improved from 22.45%. Biology rose sharply from 32.77% to 46.83%, a 14.06-point gain, but remains 4.14 points below the district's 50.97% and was below the state's 45.6% the prior year. For context, 38.4% of students receive free/reduced lunch, per-student spending is $13,199, and the student-teacher ratio is 13.7.
