Wisconsin Public Schools

What the NCES Data Says About Wisconsin Schools

Wisconsin operates 2,205 public K-12 schools organised into 451 independent school districts serving 814,921 students, per the National Center for Education Statistics Common Core of Data 2024-25. The largest district, Milwaukee School District, enrolls 67,500 pupils across 156 schools at $17,847 per student, while smaller rural districts can run fewer than a dozen campuses. This fragmentation — inherited from century-old township governance patterns in many states — is why per-pupil spending, class sizes, and programme availability vary dramatically inside a single state boundary.

Statewide, the average student-teacher ratio is 15.1:1, a useful benchmark for comparing any individual district or school on PlainSchools. Free-lunch eligibility averages 38.5% across Wisconsin public schools, a federal indicator of economic need that drives Title I funding allocations. The district table below is sortable by enrollment, school count, and per-pupil expenditure — the three fields that best predict a district's financial and demographic profile. For schools specifically, use the rankings links above to view per-category leaderboards covering spending, class size, best schools by composite quality score, chronic absenteeism, and funding-equity distribution within the state.

Every district figure here pulls from two distinct federal surveys: enrollment and demographic data come from the NCES Common Core of Data 2024-25 (school membership and directory), while per-pupil spending, teacher salaries, and federal/state/local revenue shares originate in the NCES F-33 School District Finance Survey (typically FY 2021-22). Civil-rights indicators — gifted enrollment, AP course counts, counselor staffing, chronic absenteeism, in- and out-of-school suspensions — come from the 2021-22 Civil Rights Data Collection. Cross-referencing these three sources is what lets PlainSchools produce composite scores and equity rankings that single-source tools cannot.
