Summary
Oostburg High is a 9–12 school serving 328 students in Oostburg, Wisconsin, located in Sheboygan County. It is the only high school in the Oostburg School District, which ranks 20th of 432 Wisconsin districts (95th percentile, 5 stars), and the school itself currently sits in the top 5% of Wisconsin high schools — 19th of 533, at the 96th percentile. That is the seventh consecutive reporting cycle with a 5-star rating; a decade ago it was an 85th-percentile, 4-star school, so the trend line has been steadily upward.
Test scores are where the school stands out most. In 2025–2026, 10th graders outperformed the state by about 21 to 30 percentage points in every subject tested: Science 73.56% vs. 43.20%, Math 68.97% vs. 42.93%, English Language Arts 72.41% vs. 48.47%, and Social Studies 69.23% vs. 48.25%. Among ten nearby high schools, Oostburg ranks first in Science, second in English Language Arts and Social Studies, and third in Math. Only Kohler High, 7.9 miles away, is a true academic peer — and the two schools are strong in different areas, with Oostburg ahead by about 20 points in Science while Kohler leads in Social Studies and English Language Arts.
Outcomes for students are equally striking. The school has graduated 95% or more of its students for five straight years with a 0.0% dropout rate each year, and its chronic absenteeism rate of 7.5% is less than half the state's 17.3%. Its low-income students ranked 9th of 446 schools statewide in 2025–2026 (98th percentile), and its special-education students sit in the 91st percentile. All of this comes at a per-pupil cost of $15,321 — mid-pack for the region, and far less than Cedar Grove-Belgium High's $19,730. Two things to watch: absenteeism has crept up from 4.0% to 7.5% over five years (still roughly double the district's rate), and Social Studies scores swing noticeably from year to year.
