Students earning college credit while meeting the requirements of Washington's high school diploma are basic education students. Yet every year in Washington, students and their families pay out-of-pocket for the fees, books, and supplies that are required for participation in dual credit programs. This creates inequity by only allowing students who can afford the additional costs to have access to these courses. Dual credit programs allow students to earn high school and college credit at the same time. There are two main types of dual credit programs: exam-based dual credit and concurrent enrollment dual credit. Research is clear: participation in dual credit courses increases high school and postsecondary success for students. The 2019 Legislature (House Bill 1109) directed the Office of Superintendent of Public Instruction (OSPI) to "study and make recommendations for how Washington can make dual credit enrollment cost-free to students ... within existing basic education apportionments." This report provides a high-level overview of the different types of dual credit available to Washington's students, an examination of persistent opportunity gaps, discussion of the costs of dual credit, and recommendations for eliminating costs for students and their families while increasing equitable access.
