A study examined the educational and employment activities of members of Minnesota's high school class of 1991. Data regarding 12,270 students (11,674 graduates, 218 dropouts, and 378 students school leavers not classified as dropouts) were collected from 107 high schools participating in the Minnesota Secondary School Follow-up System and from 918 of the students' employers. Current employment/education-related activities of the class of 1991 were also analyzed by curriculum area, and trend data covering the years 1978 through 1991 were summarized. At the time of the survey, over one-quarter of the class members were both employed and attending a school, 20.9 percent were employed only, 1.2 percent were unemployed and not attending a school, and one-quarter were involved in education only. The percentage of individuals employed and not simultaneously attending any school has generally declined since 1978, whereas the percentage of individuals participating in education only has remained fairly steady. (Appended are lists of secondary schools participating in the project and the specific industries and occupations within categories reported, the base data coding form, and selected survey questionnaires. Also included are 56 figures and 213 tables.) (MN)
