Summary:
Onalaska High is the only high school in the Onalaska School District in Onalaska, Wisconsin, serving grades 9 through 12. It enrolls about 925 students with a 13.8-to-1 student-teacher ratio, and roughly 27% of students qualify for free or reduced-price lunch. Per-student spending is about $15,489. In 2025–2026 the school ranked 78th of 533 Wisconsin high schools — the 85th percentile — earning 4 of 5 stars, a full star above its own district's rating. It has held 4 stars for three straight years.
Achievement beats the state average in every tested subject in both of the last two years. Mathematics is the steadiest strength, ahead of the state by about 15 to 17 points each year. English Language Arts made the biggest jump, rising about 7 points to 64.19% proficient — now the school's highest score in absolute terms and roughly 16 points above the state. Social Studies also gained and sits about 7.5 points ahead. Science is the one decline, falling about 3.7 points to 53.02%; that still runs about 10 points above Wisconsin, but it is now the lowest of the four subjects.
Completion outcomes are strong: a 96.1% graduation rate versus the state's 92.0%, and a 0.3% dropout rate, roughly a quarter of Wisconsin's 1.1%. Chronic absenteeism is 11.6%, well below the state's 17.3%, though higher than the district's 9.2% — a pattern typical of high schools, where attendance typically slips as students get older. Two items worth watching: Science's decline and attendance at the high school level. Overall, this is a consistently strong, top-15% school that outperforms the state across the board.
