Student data on 7,964 high school graduates from Colorado's largest school district were matched with data from both the Colorado Department of Labor and Employment and the Colorado Commission on Higher Education. Data collected for the 1996, 1997, and 1998 graduates examined two of the paths selected by students immediately after graduation: enrollment in postsecondary education and workforce employment. Relationships were identified in terms of gender, ethnic background, and graduation year. Data show that 1 year after graduation, approximately 45% of the study participants were enrolled in Colorado postsecondary institutions and 46% were employed in Colorado industries. More than 90% of students enrolled in postsecondary education were also employed. Exit surveys indicated that 72% of the 1996-1998 graduates planned to enroll in postsecondary education programs, and 14% indicated they planned to find full-time employment. Statistically significant differences were found between male and female and majority and minority populations in several categories. Male graduates earned significantly more than females, and minority students earned significantly more than majority students. The study demonstrates the ability of researchers to match school district data with employment and enrollment data and demonstrates that matched data can be used to identify the paths high school students select after graduation. Six appendixes contain supplemental information and some excerpts from codes, titles, and classifications used in the study. (Contains 44 tables and 69 references.) (SLD)
