Summary:
The Oconomowoc Area School District in Wisconsin has just one high school — Oconomowoc High — serving grades 9–12 with 1,591 students at 641 E Forest St in Oconomowoc. Because it is the district's only high school, its results are also the district's high school results.
Oconomowoc High is a strong performer. The district is rated 5 stars and ranks #36 of 432 Wisconsin districts, in the 92nd percentile. The school's own rank moved from #175 of 431 (59th percentile, 3 stars) in 2023–2024, up to #55 of 431 (87th percentile, 4 stars) in 2024–2025, then to #97 of 533 (82nd percentile, 4 stars) in 2025–2026 — still within the top 18% of ranked high schools. Tenth graders beat the state average in all four tested subjects in both years shown. In 2025–2026, the school led the state by 13.30 points in Mathematics, 12.75 in English Language Arts, 9.71 in Science, and 6.61 in Social Studies. The graduation rate is 97.3% versus the state's 92.0%, and the dropout rate is 0.5% versus 1.1% statewide.
The clearest concern is chronic absenteeism at 19.4%, higher than both the district's 11.5% and the state's 17.3%. Test scores also declined across all subjects from 2024–2025 to 2025–2026: Social Studies fell 7.57 points, Mathematics 3.83, Science 3.79, and English Language Arts just 0.51 — though all remain above state averages. Free/reduced lunch is 16.15%, per-student spending is $13,483, and the student-teacher ratio is 16.2.
