Summary:
Chilton, Wisconsin, a small city in Calumet County, is served by three public schools in the Chilton School District — one elementary serving PK–4, one middle school serving grades 5–8, and one high school serving grades 9–12 — with a combined enrollment of 1,037 students.
Chilton Elementary and Chilton High are the standout schools, both earning 4 stars in 2025–26. Elementary ranked 312 of 1,039 (70th percentile) and scored above the state in all six listed assessments, averaging 65.4% proficiency versus the state's 55.4%. High school made the biggest leap, rising from 2 stars and the 42nd percentile to 4 stars and the 75th percentile, with a 93.9% graduation rate and all listed subjects above state. Chilton Middle is more uneven: 3 stars and the 52nd percentile, with math above state in every tested grade in both years, but 6th- and 7th-grade ELA, 8th-grade science, and 8th-grade social studies all below state.
Chronic absenteeism is a district-wide strength — High 7.0%, Elementary 8.1%, Middle 8.8%, all far below Wisconsin's 17.3%. One item to watch: Chilton High's dropout rate of 3.1% exceeds the district's 2.5% and the state's 1.1%. Notably, spending and class size don't line up neatly with results. Chilton Middle has the highest per-student spending ($14,664) and smallest classes (10.3 students per teacher) but the lowest percentile, while Chilton High has the lowest spending ($13,247) and largest classes (13.5) yet the strongest outcomes. Overall, the district ranks 151 of 432 statewide — the 65th percentile with 3 stars — and its trajectory from 2024–25 to 2025–26 is clearly positive.
