Over the years, as states have sought to incorporate more inclusive and relevant academic standards and curriculum for K-12 students, they have interpreted ethnic studies in both broad and narrow terms. While most states use the term ethnic studies to describe their efforts to incorporate the knowledge and perspectives of traditionally excluded groups, some prefer multicultural education or diversity studies. As part of its mission to support and enhance the capacity of state, local, and regional agencies to improve education outcomes for all students, the Region 15 Comprehensive Center produced this scan to generate understanding of relevant legislative efforts across the country. To that end, it summarizes recent legislative initiatives--those between February 2019 and January 2021--that require ethnic studies to be incorporated in the K-12 standards or curricula in 19 states (i.e., California, Connecticut, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Michigan, Mississippi, Nevada, New Mexico, Oklahoma, Oregon, Texas, Vermont, Virginia, Washington, and Wisconsin) and the District of Columbia.
