Summary
Oconomowoc High is a public high school serving grades 9–12 in Oconomowoc, Wisconsin, and is part of the Oconomowoc Area School District. With 1,591 students, it is one of the larger comprehensive high schools in its area — only Arrowhead High is bigger. The school's profile is generally strong: graduation is high, dropout is low, test scores are above state averages, and results for different student groups have improved recently. The clearest relative weakness is chronic absenteeism, which has run higher than both the district and the state in recent years.
In 2025–2026, Oconomowoc High ranked in the 82nd percentile of Wisconsin high schools. That places it above North High (56th percentile) and near West High (86th), but below Pewaukee High (96th), Kettle Moraine High (95th), and Arrowhead High (99th). Its 10th-grade proficiency scores beat state averages in every reported subject, including English language arts, math, science, and social studies. Against West High, results are mixed: Oconomowoc is slightly ahead in English and math, while West is ahead in science and social studies.
Graduation has stayed high, at 97.3% in 2024–2025 versus 92.0% statewide, and dropout was just 0.5%. The standout concern is attendance: 19.4% of students were chronically absent in 2024–2025, above the district's 11.5% and the state's 17.3%. That is higher than West High, Pewaukee High, Kettle Moraine High, and Arrowhead High, though lower than North High. The school spends $13,483 per student — less than several higher-scoring nearby districts — while still producing above-state results, and it serves a more economically diverse population than Pewaukee, Kettle Moraine, or Arrowhead. Overall, Oconomowoc High is a solid, above-average school that is academically successful, with attendance and engagement the main area worth watching.
