Summary
Cassville High is a small rural public school in Cassville, Wisconsin, serving grades 7–12 with 79 students as part of the Cassville School District. Its small size — roughly 13 students per grade — shapes how its results should be read, since one or two students can shift a percentage by many points.
Rankings tell a mixed story. The district ranks 134th of 432 in Wisconsin (69th percentile, 3 stars), while the school's 2025–26 rank is 304th of 533 (43rd percentile, 2 stars), down from 63rd percentile in 2024–25. Nearby, Lancaster High (325 students, grades 9–12) and Potosi High (107 students, grades 9–12) both rank higher at the school level in 2025–26. In 2025–26 testing, Cassville's 7th- and 8th-grade results were mostly above state levels, including 8th-grade Social Studies at 88.89% and 8th-grade Science at 66.67%. High-school results were weaker: ACT Math and Science were both 35.29%, below the state and both neighbors, and 10th-grade Social Studies was 35.71%. ACT ELA (58.82%) was a bright spot, above the state and Lancaster. Note that Cassville's middle-school scores are part of its data, while the two comparison high schools serve only grades 9–12.
Completion outcomes are strong: a 100% graduation rate in 2024–25 and a 0.0% dropout rate. The main warning sign is chronic absenteeism at 26.3%, the highest of the three schools and above the state's 17.3%, though it was only 8.3% the prior year. Cassville spends $24,098 per student with a 6.8 student-teacher ratio — far more per student than Lancaster ($16,815) or Potosi ($21,579). Its low-income student subgroup ranked 65th percentile (3 stars), above the school's overall 43rd percentile.
