A quarter of Wisconsin's high school students earned some college credit in a dual enrollment program during the 2021-22 school year. The two-fold increase in students over the past decade represents a substantial potential savings of time and money for students and families, but better data collection and analysis is needed to determine how these programs affect students' readiness for the workforce or higher education. This report discusses dual enrollment programs in Wisconsin and assesses the growing impact of dual enrollment in Wisconsin. The data in this report come from the annual reports distributed by the University of Wisconsin System and the Wisconsin Technical College System (WTCS).
