Summary:
High Schools in the Penn-Harris-Madison School Corp district in Indiana are represented by a single comprehensive campus, Penn High School in Mishawaka, which serves grades 9–12 and enrolls 3,687 students.
Penn High School is a standout on statewide measures. It ranked 15th of 415 Indiana high schools in 2025–2026 (96th percentile, 5 stars), after 25th of 429 (94th percentile) and 23rd of 432 (95th percentile) in the prior two years — top 4–6% each year, with 5 stars every time. The district itself ranks 34th of 374 (91st percentile, 5 stars). Because there is only one high school, school and district high-school figures mirror each other. The graduation rate is 97.5%, well above the state's 89.7%, and chronic absenteeism is 8.0% at the school (8.4% district) versus 16.7% statewide — less than half the state rate. Proficiency is above state averages in every reported subject: SAT Evidence-based Reading and Writing at 71.69 versus 51.9, SAT Mathematics at 43.5 versus 25.6, and Biology at 61.49 versus 45.6 in 2024–2025. The 2025–2026 Biology result is 71.44, with no state comparison provided.
The clearest internal gap is mathematics: SAT Math proficiency of 43.5% sits about 28 percentage points below SAT ERW, even though it remains far above the state benchmark. Biology showed the strongest recent movement, rising from 61.49% to 71.44%, a gain of nearly 10 percentage points, while SAT ERW (72.04 to 71.69) and SAT Math (43.49 to 43.50) were essentially flat. About 31.14% of students qualify for free or reduced lunch, per-student spending is $9,872, and the student-teacher ratio is 19.5:1.
