Summary:
Delphi, Indiana has one high school serving grades 9–12: Delphi Community High School, part of Delphi Community School Corp. With 397 students, a 10.9 student-teacher ratio, 49.12% of students receiving free or reduced lunch, and $13,161 in per-student spending, the school is a small, moderately sized high school with a relatively low student-teacher ratio. Its graduation rate is 88.3%, just 1.4 percentage points below the state's 89.7%, and identical to the district rate.
The school's record is mixed and has shifted over time. In 2023–2024 it ranked 89th of 432 Indiana high schools — the 79th percentile with 4 stars — but by 2025–2026 it had fallen to 189th of 415, the 54th percentile with 3 stars, a drop of 100 rank positions and 25 percentile points. The district overall is ranked 203rd of 374 districts, in the 46th percentile with 2 stars, so the high school's latest standing is only modestly above the district's. Test results point in different directions: Biology ILEARN End-of-Course proficiency was 60.22% in 2024–2025, well above the state's 45.6%, though it fell to 48.91% in 2025–2026 with no state figure reported for comparison. SAT Evidence-based Reading and Writing held steady at 48.48% but remains below the state's 51.9%, while SAT Mathematics proficiency was only 18.18%, roughly 7 points behind the state's 25.6% and down from 20.2% a year earlier.
The clearest red flag is chronic absenteeism: 25.3% in 2024–2025, above the state's 16.7% and more than double the district's reported 12.2%. Parents should also note that district and school figures are identical for test scores and graduation, suggesting the district numbers are driven largely by this school. The most important things to watch are the downward ranking trend, low SAT Math proficiency, and the high absenteeism rate, while Biology performance and graduation rates remain relative strengths.
