This report provides a general overview of the activities and experiences of the high school sophomores of 1980, using information from High School and Beyond's (HS&B) base-year, first follow-up (1982), and second follow-up (1984) surveys. It contains a summary of descriptive information about 1980 sophomores two years after leaving high school--their educational, vocational, socioeconomic, and familial status, and their plans and attitudes. The report demonstrates the wealth and depth of the data and presents some illustrative findings from the preliminary analyses. The remainder of the material, Chapters II through V, is organized into five topical areas. Chapter II provides an overview of what 1980 sophomores were doing in the spring of 1984; Chapter III describes their education experiences (equivalent diplomas for dropouts, enrollment in postsecondary education, field of study, and financing); Chapter IV, their labor force experiences (employment status, type of job, and earnings); Chapter V, their experiences with electronic equipment, their voting behavior, and their life goals. Appendices contain: (1) the HS&B data files available for public use; (2) the 26 classification variables used to define subgroups for analysis; and (3) technical notes on the sample design and data quality.
