This publication presents a summary of the research obtained from senior high schools in Minnesota that used the Minnesota Secondary School Follow-Up System to collect data on the class of 1987. Data were collected from 84 high schools, plus a sampling of Minneapolis, with responses received from 10,705 students (76.8% of those surveyed). Of the total sample of 13,945, 13,165 students were graduates, 360 were classified as dropouts, and 420 were defined as having left high school without a diploma but not classified as dropouts. The report is organized in five chapters, all of which consist largely of data tables. The first chapter introduces the study and reports on the methodology and population. Chapter 2 presents a summary of activities for all respondents, as well as comparative data from the classes of 1977-1981 and 1983-1986 (data from the class of 1982 and career planning data from the class of 1983 were not available). Chapter 3 compares the plans versus the actual activities of the class of 1987. The data were collected via the Career Planning Survey component of the Follow-Up System, administered to seniors about 1 month prior to graduation. Chapter 4, a summary of the class by curriculum area, shows the potential relationships between the amount of coursework taken and post-high school employment and educational activities. Chapter 5 presents information collected by a survey of employers of members of the class of 1987. Appendices list participating schools and industry and occupational categories used and include the questionnaires. (KC)
