Summary:
ZIP code 53021 (Fredonia, Ozaukee County, Wisconsin) is served by four public schools — Ozaukee Elementary (PK–5, 344 students), Wisconsin Virtual Learning (PK–12, 337), Ozaukee High (9–12, 199), and Ozaukee Middle (6–8, 174) — all operated by the single Northern Ozaukee School District and sharing one campus at 401 Highland Dr, for 1,054 students total. The district is rated 159th of 432 Wisconsin districts (63rd percentile, 3 stars).
Three of the four schools outperform that district rating. Ozaukee Middle earned 4 stars in all three ranked years, placed 8 of 8 tested grade-subjects above the state average in 2025-26, and did it on the lowest per-student spending in the ZIP ($9,491). Ozaukee High posts a 97.4% graduation rate, a 0.0% dropout rate, and chronic absenteeism of just 2.1% — far below the 17.3% state rate — with ACT results above state on all four measures and the smallest classes (10.3:1). Ozaukee Elementary is above state in all three ELA grades and both science/social studies grades, but below state in 3rd and 4th grade math. Wisconsin Virtual Learning is unranked by the state and is the clear outlier: math proficiency ranged from 0% to 40% across grades 3–8, far under the state's ~52–56% band, alongside the ZIP's highest student-teacher ratio (24.4:1) and highest free/reduced lunch rate (35.61%).
Patterns worth noting: spending and results run in opposite directions here, with the lowest-spending middle school producing the strongest relative outcomes; chronic absenteeism is oddly inverted, highest at the middle school (14.5%) and lowest at the high school (2.1%); and science and social studies are a quiet strength, with social studies roughly 14 points above state at both the elementary and middle levels. Virtual-school grade figures rest on very small cohorts, so treat them as directional rather than precise.
