Summary:
New Glarus High is the only public high school in the New Glarus School District, serving grades 9–12 to about 320 students at 1701 2nd St in New Glarus, Wisconsin. Because it is the district's sole high school, school and district figures for graduation, dropout, and test scores are essentially the same.
The school is one of Wisconsin's top-ranked high schools. In 2025–2026 it placed 14th of 533 high schools, in the 97th percentile with 5 stars, after ranking 23rd in 2023–2024 and 57th in 2024–2025 — a dip followed by a strong rebound. The district itself ranks 16th of 432 districts, in the 96th percentile with 5 stars. Test proficiency far exceeds state averages: in 2025–2026, 73.97% in Social Studies (state 48.25%), 73.85% in English Language Arts (state 48.47%), 75.38% in Mathematics (state 42.93%), and 70.77% in Science (state 43.20%). The largest gap was Mathematics, 32.45 points above the state. Every subject improved over the prior year, with English Language Arts gaining the most, up from 55.26% to 73.85%.
Completion outcomes are excellent: a 97.9% graduation rate and a 0.0% dropout rate, both better than the state's 92.0% and 1.1%. Chronic absenteeism is the main local tension at 15.1% — below the state's 17.3% but well above the district's 8.8%, suggesting attendance is more of a challenge at the high school level than elsewhere in the district. Context for families: 14.69% of students qualify for free/reduced lunch, per-student spending is $15,609, and the student-teacher ratio is 14:1.
