Summary
Slinger High is a public high school in Slinger, Wisconsin — a suburban community in Washington County about 30 miles northwest of Milwaukee — serving roughly 1,065 students in grades 9–12 as part of the Slinger School District. It ranks 37th of 533 Wisconsin high schools in 2025–2026, placing it in the 93rd percentile with a 5-star rating, and it has earned 5 stars every year in the available history from 2015–2016 through 2025–2026, with statewide ranks ranging from 10th to 37th.
Test results in 2025–2026 were well above Wisconsin averages in every reported area: 70.27% of 10th graders met or exceeded expectations in English Language Arts on the ACT (state: 48.47%), 69.50% in math (state: 42.93%), 59.07% in science (state: 43.20%), and 63.36% in 10th-grade social studies on the Forward Exam (state: 48.25%). Among nearby schools, Cedarburg High, Hamilton High, and Arrowhead High generally score higher and rank higher statewide, while Slinger outperforms Menomonee Falls High, Germantown High, East High, West High, Kewaskum High, and Hartford High on most measures. Math is a relative strength; science slipped from 74.02% the prior year to 59.07%, still above the state but worth watching.
Completion and engagement outcomes are exceptional: a 99.2% graduation rate and 0.0% dropout rate in 2024–2025, with 4.6% chronic absenteeism compared to Wisconsin's 17.3%. Slinger achieves this at $13,660 per student — less than most nearby districts. Most student groups rank well, including low-income students (92nd percentile), female students (93rd), and male students (89%). The clearest weak spot is special education students, who rank in the 33rd percentile with 2 stars, far below the school's overall results. Overall, Slinger High is a consistently high-performing, efficient school in the strong second tier behind Cedarburg, Hamilton, and Arrowhead.
