Outcomes are strong compared with Indiana.

SAT math was 40.19% versus 25.6% statewide in 2025–2026, and 42.04% versus 25.4% the year before—still above state, but about 34–35 points below reading/writing.

Additional context: 43.83% of students qualify for free/reduced-price lunch, per-student spending is $12,031 (2023–2024), and the student-teacher ratio is 10:1. The data does not provide state averages for those three metrics, so direct comparisons are not possible. Overall, Herron High School is a high-performing charter high school with top-percentile state rankings, strong graduation and attendance, excellent SAT reading/writing, above-state SAT math, and improving Biology scores. The main patterns to watch are the large reading/writing advantage over math and the slight SAT decline.
