Northern Ozaukee School District

The Northern Ozaukee School District serves about 1,154 students across five schools — two elementary, one middle, one high school, and one alternative PK–12 school — covering grades PK through 12. The district ranks 159th of 432 Wisconsin districts, at the 63rd percentile with 3 stars, but that same district rating appears on every school record, so it masks real differences between campuses. Three individual schools have recently ranked at the 4-star level.

Ozaukee High is the strongest overall performer: chronic absenteeism of 2.1% (well below the district's 10.8% and the state's 17.3%), a 97.4% graduation rate, a 0.0% dropout rate, and ACT scores above both district and state in ELA, math, and science. It also has the lowest student-teacher ratio (10.3) and the highest per-student spending ($15,347). Ozaukee Middle beats state proficiency in every reported 2025-26 subject and grade — ELA at 62%, 70.18%, and 80.7%, and math at 60%, 63.16%, and 73.68% — despite the district's lowest per-student spending ($9,491) and its highest chronic absenteeism (14.5%). Sugar Maple Nature School, with just 100 students in grades K–7, posts standout figures such as 100% ELA 7 and 91.67% ELA 4, with 8.2% chronic absenteeism, though its small size makes percentages swing easily.

Families should weigh some caveats. Wisconsin Virtual Learning, an alternative PK–12 school, has a severe math gap: 2025-26 math proficiency in grades 3–8 ranged from 0% to 40%, about 18.8% on average, though its ACT ELA and science scores beat the state and its graduation rate is 96.3%. Ozaukee Elementary is mixed — strong in 5th grade ELA and math and in 4th grade science and social studies, but math in grades 3 and 4 fell below state. Every school is below the state's 17.3% chronic absenteeism rate. Note that Sugar Maple's free/reduced lunch figure is unknown, and small grade-level cohorts can make year-to-year swings volatile.
