Summary:
Clayton School District is home to a single middle school: Clayton Middle, a grades 5–8 building with 46 students on Polk Avenue in Clayton, Wisconsin. Because it is the district's only middle school, every district-level middle-grade test figure in the data is simply this school's figure, with no averaging across buildings — parents can read the district's middle-grade results as this school's results.
Clayton Middle has climbed sharply in state rankings over two years, from 402nd of 641 schools (37th percentile, 2 stars) in 2023-24, to 233rd of 628 (63rd percentile, 3 stars) in 2024-25, to 212th of 643 (67th percentile, 3 stars) in 2025-26. That puts it in the upper third of its peer group, while Clayton School District as a whole rates 280th of 432 (35th percentile, 2 stars). In 2025-26 the school scored above the state in 8 of 10 tested subject-and-grade combinations, averaging 61.5 against the state's 55.0. Eighth grade is the engine: Social Studies 83.33 vs. 64.63, Science 66.67 vs. 51.86, and ELA and Math both 66.67, against 54.38 and 53.67.
Two areas lag. Sixth-grade math scored 36.84 against a state figure of 53.6 — the lowest result in the data — and fifth-grade ELA scored 50 against 53.63. Chronic absenteeism of 15.6% is better than the state's 17.3% but worse than the district's 12.4%. Meanwhile 52.17% of students receive free or reduced-price lunch, per-student spending is $19,351, and the student-teacher ratio is a low 10.9:1. With grade-level cohorts of roughly a dozen students, one child can move a percentage several points, so the upward ranking trend and the consistent 8th-grade strength are the signals worth trusting most.
