Academically, the school outperforms the state in every reported subject. In 2024–2025, its proficiency leads over the state were largest in Mathematics (+17.33 points), Social Studies (+14.76), Science (+13.28), and English Language Arts (+13.11). In 2025–2026 it still led the state in all subjects, though every score declined from the prior year — Social Studies fell 7.57 points, Mathematics 3.83, Science 3.79, and ELA 0.51. Even its lowest 2025–2026 result, Science at 52.91, remained well above the state's 43.20. Its ranking improved from 3 stars and the 59th percentile in 2023–2024 to 4 stars and the 87th percentile in 2024–2025, easing slightly to 4 stars and the 82nd percentile in 2025–2026 — still within the top 18% of Wisconsin high schools.

Outcomes are strong: the 97.3% graduation rate is 5.3 points above the state's 92.0%, and the 0.5% dropout rate is less than half the state's 1.1%. The clearest warning sign is chronic absenteeism at 19.4%, above both the state's 17.3% and the district's 11.5%. Context figures — a 16.15% free/reduced lunch rate, $13,483 per-student spending, and a 16.2:1 student-teacher ratio — have no state benchmarks in this data set, so they cannot be judged as high or low.
