Summary:
ZIP code 54651, in and around Ontario, Wisconsin, has just one public high school: Brookwood High, a combined middle and high school serving grades 7 through 12 with 264 students, part of the Norwalk-Ontario-Wilton School District.
Brookwood's standing has climbed sharply in recent years. It rose from 334th of 431 schools in 2023–24 (1 star, 23rd percentile) to 61st of 431 in 2024–25 (4 stars, 86th percentile), then held strong at 120th of 533 in 2025–26 (4 stars, 77th percentile). High school results are the brightest spot: 10th-grade ACT proficiency beat the state in all three subjects in 2025–26 — English language arts at 66.67% vs. 48.47%, math at 44.44% vs. 42.93%, and science at 48.89% vs. 43.20% — and 10th-grade social studies was 58.82% vs. 48.25% statewide. Middle-grade results are weaker: 7th-grade ELA was 34.15%, 21.18 points below state, and 7th-grade math was 41.46%, 14.21 points below state, while 8th-grade math fell from 53.66% to 41.18%. Because the school spans grades 7–12, its middle-grade and high-school outcomes are best read separately.
Attendance is a clear strength: chronic absenteeism of 7.7% is well below the state's 17.3%. The 82.0% graduation rate, however, trails the state's 92.0%, even though the 1.1% dropout rate matches the state exactly. With $16,488 spent per student and a 12.6:1 student-teacher ratio, plus only 264 students across six grades, year-to-year swings of 10–20 percentage points can represent just a handful of students, so single-year changes deserve caution.
