This report summarizes and documents the major technical aspects of the High School and Beyond First Follow-Up survey. Student data were collected (through questionnaires and tests) from samples of the 1980 High School and Beyond Base Year survey sophomore and senior cohorts, and school data from administrators. High school transcripts for a subsample of participating 1980 sophomores were also gathered. The purposes and major surveys of the National Center for Education Statistics' Longitudinal Studies Program are reviewed. The tests and questionnaires used for the Follow-Up Survey are described. Summary Base Year and detailed First Follow-Up information is provided on: sample design and implementation; data collection; data control and preparation; and data processing. Separate chapters are devoted to the technical aspects of the Transcripts Survey and the Course Offerings and Enrollments Survey. The appendices contain the questionnaires, correspondence from the pre-field and field periods, and critical items for each of the instruments. (BS)
