Details of the High School and Beyond's Second (1982) Follow-Up survey are presented. Probability samples of approximately 15,000 1980 sophomores and 12,200 1980 seniors were retained for the second follow-up. The former students were asked to complete a questionnaire detailing their post-high school activities. Technical aspects of the survey are documented, including the survey forms used, sample design and implementation, and the data collection and data processing procedures used in the base year survey and both followups. Details are also provided on the 1984 sample selection, weighting procedures, sampling variances, and the implications of survey nonresponse for sample estimates and precision. Completed cases for 1980 seniors numbered 10,925; for 1980 sophomores, 13,682. Data were collected from a mail survey. Items involved background information, education, military and other training, work experience, family characteristics, income, experiences and opinions, and life goals. New items included computer literacy and parental financial assistance for education. Appendices include the Second Follow-Up Questionnaires for Seniors and for Sophomores, correspondence, High School and Beyond database descriptions, and design effects and sampling errors. (GDC)
