"Getting Prepared 2021" examines Minnesota public high school graduates from the classes of 2013-2020 who enrolled in postsecondary education and those enrolled in developmental education. This report provides insight into the academic readiness of Minnesota public high school graduates. Developmental education courses add to the overall cost of college for students in terms of both tuition and opportunity costs for students who spend additional time finishing developmental course requirements before starting program-specific courses. "Getting Prepared 2021" fulfills the legislative mandate (Minnesota Statute 13.32, subdivisions 3 and 6) to provide summary information about Minnesota public high school graduates who enrolled in developmental courses at Minnesota postsecondary institutions within two years of high school graduation. The report utilizes analysis resulting from linking student level data within the Minnesota Statewide Longitudinal Education Data System (SLEDS) on Minnesota public high school graduates from the Minnesota Department of Education with college enrollment data from the Minnesota Office of Higher Education and the National Student Clearinghouse.
