A study examined the transition from secondary to post-secondary education and the opportunities for academic preparation and planning available to Minnesota secondary students. Data concerning post-secondary enrollment patterns, curriculum, planning, and remedial and developmental studies were gathered from a number of sources. Extensive results included the following: (1) statewide, 77% of public high school juniors planned to enroll in some type of post-secondary institution immediately after high school; (2) state high school graduation requirements fall far below the preparation that most four-year Minnesota colleges expect but that only the University of Minnesota and some liberal arts colleges require; (3) students' opportunities for post-secondary planning depend on the secondary schools in which they are enrolled; (4) just over 15% of all community college students in a year are enrolled in courses that community colleges term remedial/developmental; and (5) many students, including some who had opportunities, are attending college without sufficient preparation to do the work required there. (Five tables, eight figures, and three maps of data are included; five maps of post-secondary system attendance rates by school district and an appendix containing remedial/developmental course descriptions of the state university system are attached.)
