This bill amends the Financial Literacy and Education Improvement Act to extend financial literacy best practices guidance to secondary schools, which were previously excluded from the law. The legislation requires the development of new best practices specifically designed for high school students, covering topics like budgeting, saving and investing, credit fundamentals and credit scores, identifying financial scams, and understanding postsecondary education financing options including student loans. The bill also updates an outdated deadline in the law from May 2018 to January 1, 2027, giving education officials time to develop and implement the new secondary school standards. The changes affect secondary schools and school districts across the country, along with institutions of higher education that were already covered under the original law. No specific funding amounts are included in the bill text, though it directs the relevant federal agencies to develop and promote these best practices for teaching financial literacy to high school students.
