The Wisconsin Department for Public Instruction (DPI) is required to submit this report to the Legislature regarding the status of existing charter schools, the number of petitions for new charter schools, and the action taken by school boards and the DPI on petitions for new charter schools. This report offers the results of new charter school activity in the 424 Wisconsin school districts during the 2015-2016 school year. This report documents two distinct levels of decision-making regarding charter school proposals. A first-level decision occurs during the charter school's "development" stage. The school district may approve further study of a charter school concept, participate in a consortium of school districts interested in opening a charter school, or sign a planning grant with the purposes of seeking federal charter school planning funds from DPI. A second-level decision occurs during the "implementation" stage. The school district issues a charter school contract, provides a signature on an agreement to participate in a multi-district charter school, or signs an implementation grant with the purpose of seeking federal charter school start-up funds from DPI. The department conducted an electronic survey and personally contacted school district officials to compile the necessary data. One hundred percent of the Wisconsin school districts responded to the survey. During the 2015-2016 school year, eight districts (1.9 percent) reported charter school activity as defined above, including at least one district in six of the 12 regional Cooperative Educational Services Agencies (CESA). A breakdown of the activity shows six school boards made seven first-level charter school decisions, and six school boards made six second-level charter school decisions. Of the first-level decisions, seven of seven (100 percent) were approved. Of the second-level decisions, six of six (100 percent) were approved.
