The National Education Longitudinal Study of 1988 (NELS:88) is the first nationally representative longitudinal study of eighth grade students in public and private schools. It is sponsored by the National Center for Education Statistics to provide longitudinal data about critical transitions experienced by young people as they develop, attend school, and embark on their careers. In 1988, some 25,000 eighth graders, their parents, teachers, and school principals were surveyed. In 1990, the same students (most of whom were in 10th grade, although some were dropouts) and their teachers and school principals were surveyed. The second followup was conducted in 1992, and the third in 1994. This CD-ROM contains public release data from the NELS:88 base year and followup surveys and an Electronic Codebook System (ECB) in two datasets. The first set and its ECB integrate student, parent, transcript, school administrator, and teacher data from the base year through the second followup. The second data set and its ECB contain base year through third followup (1994) records for the subsample of second followup sample members who responded. The CD-ROM also contains descriptions of the methodology and users' manuals in WordPerfect format. Installation information is included.
