More than 1 million U.S. high schoolers participate each year in dual enrollment, taking college courses that simultaneously fulfill high school graduation requirements and count toward a postsecondary degree or workforce credential. While most systems still have equity gaps in dual enrollment access, 20 percent do not. In "The Dual Enrollment Playbook: A Guide to Equitable Acceleration for Students," the Aspen Institute and the Community College Research Center examines nine dual enrollment programs in Florida, Ohio, and Washington that have narrowed or closed equity gaps in dual enrollment for Black, Latinx, Indigenous, and Pacific Islander students. These K-12 and community college partnerships show that it is possible to close equity gaps when intentional strategy is paired with innovation and commitment. Using the results of this research, the "Dual Enrollment Playbook" identifies five principles and the supporting strategies and practices through which community college and K-12 leaders can advance equity in high-quality dual enrollment.
