Summary
Luxemburg-Casco High is a 9–12 high school in Luxemburg, Wisconsin, serving 661 students as part of the Luxemburg-Casco School District, which ranks 52nd of 432 Wisconsin districts (88th percentile, 4 stars). The school is a 4-star school in 2025–2026, ranked 127th of 533 high schools (76th percentile). After a dip in 2021–2022 (38th percentile, 2 stars), it returned to the top quartile and has stayed there. Completion outcomes are among the strongest in the area: the 2024–2025 graduation rate was 98.0%, above the state's 92.0%, and the dropout rate was 0.6%, below the state's 1.1%. For comparison, Denmark High graduated 94.1% and Kewaunee High 91.5%.
Academically, the school scored above the Wisconsin average in all four reported 10th-grade subjects in 2025–2026. Mathematics is the standout at 58.82% proficient versus 42.93% statewide — roughly a 16-point advantage — and social studies is also well above state (59.12 vs. 48.25). English language arts (52.35 vs. 48.47) is above state but less dominant, and science (45.29 vs. 43.20) is only modestly above state and has slipped from 50.34 in 2023–2024, making it the subject to watch. In 2025–2026 the school outperformed Denmark High, Kewaunee High, Algoma High, Preble High, West High, and East High in every subject, though nearby Denmark and Kewaunee have shown subject-specific strengths in individual years.
The clearest weakness is attendance. Chronic absenteeism was 24.1% in 2024–2025, more than double the district's 11.6% and above the state's 17.3%, and it has risen from 18.9% in 2020–2021. Denmark High, a similar nearby school, sits at 6.7%. Subgroup effectiveness is also uneven: female students rank at the 85th percentile while male students are at the 50th, and English language learner students (17th percentile), special education students (37th percentile), and low socio-economic status students (14th percentile, down from the 63rd in 2023–2024) rank much lower. Notably, the school achieves these results while spending less per student ($12,834) and carrying a higher student-teacher ratio (16.7) than many nearby districts.
