Assembly Bill 646 mandates the Department of Public Instruction (DPI) to contract an entity to conduct a comprehensive study of school districts in Wisconsin. The study will examine various aspects, including school district boundaries, potential consolidations, existing facilities, staffing levels, and the demographics of school-age children. The contracted entity is required to submit a detailed report to DPI, which will include recommendations for changes to school district boundaries, assessments of existing facilities, projections of school-age populations, and suggestions for consolidations that are efficient and viable. The report must also provide specific information about each recommended consolidation, such as estimated enrollment and the locations of existing school buildings.

Additionally, the bill requires DPI to submit a request for supplemental funding to the Joint Committee on Finance to support the study's implementation. The report generated from this study must be shared with the legislature, ensuring that lawmakers are informed of the findings and recommendations regarding school district consolidations and improvements. This initiative aims to enhance the efficiency and effectiveness of school districts across the state.
