Summary

Waterloo High is a small public high school in Waterloo, WI, serving grades 9–12 with 232 students as part of the Waterloo School District. The district ranks 348th of 432 districts — 19th percentile, 1 star — but the school recently ranked higher than its district: 320th of 533 high schools in 2025–2026, or 40th percentile, 2 stars, up from 15th percentile, 1 star in 2024–2025. Its 2024–2025 graduation rate was 93.2% vs. 92.0% state, dropout was 0.8% vs. 1.1% state, and chronic absenteeism was 15.7% vs. 17.3% state, a large improvement from 40.2% in 2021–2022.

In 2025–2026 10th-grade proficiency, Social Studies was the relative strength at 48.89%, slightly above the 48.25% state rate and ahead of nearby Watertown High and Marshall High. English Language Arts was 45.16%, below the 48.47% state rate but above Watertown and Deerfield High. Math and science are the clearest weaknesses: both at 33.87%, well below the state rates of 42.93% and 43.20%, and far below nearby Lake Mills High (63.54% math, 65.63% science) and Cambridge High. Waterloo’s overall rank is similar to Marshall High and Watertown High (41st percentile), higher than Prairie Phoenix Academy (11th percentile, 1 star), but lower than Columbus High, Sun Prairie East High, Cambridge High, Lake Mills High, and Endeavor Charter School.

A standout result is Waterloo’s performance with low-SES students: in 2025–2026 the subgroup ranked 86th of 446, or 81st percentile, 4 stars, far above the school’s overall rank and up from 9th percentile two years earlier, though small cohorts can make such swings volatile. Waterloo serves a relatively high-need population, with 37.93% free/reduced lunch, second-highest among nearby schools after Prairie Phoenix Academy; per-student spending is $16,217 and the student–teacher ratio is 14.2. Spending alone does not explain outcomes: Waterloo spends more than Lake Mills High, yet Lake Mills performs higher in every subject, while Endeavor Charter School spends only $8,677 and ranks at the 93rd percentile. Overall, Waterloo has encouraging recent gains in Social Studies, ELA, and attendance, but math and science remain well below state and peer averages.
