Summary
Clayton High is a very small rural public high school in Clayton, Wisconsin, serving 86 students in grades 9–12 as part of the Clayton School District. Its standout strength is completion: the school has posted 100% graduation rates from 2021–22 through 2024–25, with a 0.0% dropout rate in 2024–25, both above state averages. Classes are also the smallest among nearby schools, with a student–teacher ratio of 8.5 and per-student spending of $20,741 in 2024–25 — the highest in its comparison group. The district itself is ranked 280th of 432 Wisconsin districts.
Academics are the bigger question mark. In 2025–26, Clayton High ranked 442nd of 533 Wisconsin high schools (17th percentile, 1 star), down from the 32nd–36th percentile in 2023–24 and 2024–25. Tenth-grade proficiency fell below the state in every subject, and was the lowest among nearby schools in Social Studies (8.33%, versus 48.25% statewide) and English Language Arts (25.00%, versus 48.47%). Math (28.57%) and Science (32.14%) were also below state. By contrast, nearby Glenwood City High and Amery High are currently much higher-ranked. Because only 86 students attend, a handful of test-takers can swing these percentages sharply from year to year, though ELA has stayed below state across multiple years.
Chronic absenteeism, at 17.3%, matches the state average but is above the district's 12.4% and higher than most nearby schools. Subgroup results are mixed: effectiveness for low-income students was comparatively strong, ranking in the 64th to 77th percentile in recent years, while other subgroup rankings fell in 2025–26. Overall, Clayton High pairs excellent completion outcomes and generous resources with recent, sometimes severe, test-score weakness — especially in English Language Arts and Social Studies.
