Since 1994, Wisconsin school districts have been primarily funded by a combination of state aid and local property taxes. Each school district in Wisconsin has a revenue limit created by the state budget. In most cases across the state, the revenue limits have not kept pace with inflation. Most districts in the state have used operating referendums to meet their budget challenges. The majority - 82% - of Wisconsin school districts have proposed operating referendums. Since 2018, 83% of operating referendums have passed.
