Funding

How Wisconsin funds schools

Wisconsin funds districts mainly through Equalization Aid, a three-tier guaranteed-tax-base formula in which state aid falls as a district’s property value per pupil rises, paired with revenue limits that cap the combined total of state general aid and local property taxes per pupil. On top of the formula, districts receive flat per-pupil categorical aid — $742 per pupil under the 2025–27 budget.

District-level per-pupil spending and the local/state/federal revenue split for Janesville School District are published in the federal school-finance files — see the full-data links below for the current figures.
