Summary:
ZIP code 54165 has just one public high school — Seymour High — which serves grades 9–12 with 590 students as part of the Seymour Community School District in Seymour, Wisconsin. Because it is the only high school in the area, the most useful comparisons are between Seymour High and Wisconsin state averages, and between the school's own results from year to year.
Seymour High's strongest results are in completion and momentum. Its 95.8% graduation rate in 2024–25 tops Wisconsin's 92.0%, and its dropout rate of 0.1% is far below the state's 1.1%. Average test proficiency across the four reported subjects rose from 39.55% in 2024–25 to 41.38% in 2025–26, while the state average stayed nearly flat. Social Studies posted the biggest gain (+9.81 points, from 35.11% to 44.92%) and English Language Arts rose 4.29 points (38.46% to 42.75%). The school's rank also improved, moving from the 26th percentile (1 star) to the 42nd percentile (2 stars).
The clearest concern is attendance: 24.9% of students were chronically absent in 2024–25, compared with 17.3% for both the district and the state. In 2025–26 the school also trailed the state in all four reported subjects, with the widest gap in Math (35.88% vs. 42.93%) — and Math and Science both declined from the prior year, with Science dropping from above the state to below it. For context, Seymour High spends $17,711 per student, has a 14.8:1 student-teacher ratio, and 29.15% of students receive free or reduced lunch; no state comparisons were provided for those figures.
