This report provides data from a nationally representative survey of Title IV degree-granting postsecondary institutions on the topic of dual enrollment of high school students. Survey respondents at selected postsecondary institutions were asked to report on the prevalence of college coursetaking by high school students at their institutions during the 2002–03 12-month academic year, both within and outside of dual enrollment programs.
