This dataset includes boundaries for all school district boundaries within the state of Wisconsin. By law, all territory in the state must be included within a public school district. The US Census Bureau identifies three types of school districts. Unified school districts serve children of all grade levels, Elementary primarily serve students in the elementary grades, and Secondary primarily serve children in grades 9-12. Out of 421 school districts in Wisconsin, 43 are considered elementary districts, 10 are secondary districts, and 368 are unified districts. Elementary and secondary school districts overlap. This layer is an aggregate of county-submitted data for school district boundaries.Each year, there is a chance for reorganizations to take place that either transfer territory between school districts or consolidate/dissolve/create districts. These reorganizations go into effect on July 1st of each year. In 2024, there were three (3) reorganizations that involved unified school districts and one (1) reorganization involving secondary and elementary districts. The reorganizations took place in Iowa, Waukesha, and Winnebago counties. Transfers of territory took place between the following pairs of districts: Iowa-Grant and Mineral Point, Norris and Washington-Caldwell, Norris and Waterford UHS, and Omro and Oshkosh. Please refer to the property transfer log for more information.This is not an official authoritative statewide dataset for school district boundaries nor does one exist for Wisconsin. These boundaries are updated annually around July 1 to reflect boundary changes from the reorganization process and as needed throughout the rest of the year.
