Is a high school course with personal finance concepts required to be taken as a graduation requirement? No, Wisconsin does not require any specific courses for graduation. See: Wisconsin High School Graduation Requirements.
In 2006, a statewide task force consisting of representatives from both the public and private sector developed Wisconsin's Model Academic Standards for Personal and Financial Literacy. These standards are rigorous and are to be used by local districts and teachers as guidelines (but are not mandatory) for developing local grade-by-grade curriculum. See: Wisconsin Personal Finance Standards.
In 2010, a Governor's Council on Financial Literacy was created. See: Wisconsin Governor's Council. The Council's mission is to improve financial literacy in Wisconsin by expanding teacher training in financial literacy, incentivizing K-16 educational institutions to implement financial literacy through grants and awards, and providing an annual report on its progress to the Governor and the Department of Financial Institutions' Office of Financial Literacy. See: Wisconsin Executive Order Creating the Council. In 2015, the Department of Financial Institutions and the Department of Public Instruction released a Financial Literacy Survey Report. According to the report, 64% of Wisconsin school districts with high schools have a personal finance requirement for graduation, either as a discrete course or embedded in a course required for graduation. See: Wisconsin Financial Literacy Highlights. In 2017, the Wisconsin State Assembly passed legislation directing "each school board [to] adopt academic standards for financial literacy and incorporate instruction in financial literacy into the curriculum in grades K-12." The companion Senate Bill 212 is currently under consideration. See: Wisconsin Assembly Bill Requiring Financial Literacy Standards.
