Summary
Penn High School is a large public high school in Mishawaka, Indiana, serving 3,687 students in grades 9–12 as part of the Penn-Harris-Madison School Corp. Its district ranks 34th of 374 Indiana districts (91st percentile, 5 stars), and the school itself ranks 15th of 415 Indiana high schools in 2025–2026 (96th percentile, 5 stars). Penn's performance is not a one-year spike: across the years shown, it has never fallen below the 94th percentile statewide and has earned 5 stars every year since at least 2015–2016.
The gap between Penn and its neighbors is wide. The next-strongest nearby school, Jimtown High School, sits at the 81st percentile, while Adams High School (45th), Mishawaka High School (31st), Elkhart High School (23rd), and Riley High School (16th) land in the bottom half of the state. Penn's proficiency beats the statewide figures in every subject reported: 71.69% in SAT reading and writing (state 51.9%), 43.5% in SAT math (state 25.6%), and 71.44% in Biology. Its 97.5% graduation rate tops every nearby school and the state's 89.7%, and its 8.0% chronic absenteeism rate is less than half the state rate of 16.7% — nearby schools range from 26.1% to 86.1%.
Penn serves a broad range of students well: in 2025–2026, every reported student group earned 4 or 5 stars, with percentiles running from 76th to 96th, and special education, English learner, and low-income students all rank well above average. Penn also has the largest enrollment, the highest student-teacher ratio (19.5), and the lowest per-student spending ($9,872) among nearby schools with data, yet produces the best results — an efficiency outlier rather than proof of cause. Two items worth monitoring: the free/reduced lunch rate rose from 24.93% in 2023–2024 to 31.14% in 2024–2025, and SAT math proficiency has hovered in the low-to-mid 40s while reading and biology stay much higher. Even so, math remains 17.9 points above the state average.
