 National Education Longitudinal Study

The National Education Longitudinal Study of 1988 (NELS:88) is a survey that began with a nationally representative sample of 1988 8th-graders and surveyed them every 2 years until 1994 and again in 2000.7 Respondents’ teachers and schools were also surveyed in 1988, 1990, and 1992, while parents were surveyed in 1988 and 1992. In contrast to previous longitudinal studies, NELS:88 began with 8th-graders in order to collect data regarding the transition from elementary to secondary education. For the purpose of providing a comparison group to 1980 sophomores surveyed in one High School and Beyond Institutional Study (HS&B), the NELS:88 sample was also “freshened” with new participants who were 10th-graders in 1990. The sample was also “freshened” in order to create a representative sample of 1992 seniors for the purpose of conducting trend analyses with the 1972 and 1982 senior classes (NLS-72 and HS&B).

In spring 1992, when most of the NELS:88 samples were 12th-graders, the second follow-up took place. This survey focused on the transition from high school to both the labor force and postsecondary education. Students identified as dropouts in the first follow-up were also resurveyed in 1992. In the spring of 1994 and 2000, the third and fourth follow-up surveys were administered and provide data on students’ postsecondary persistence and attainment. The 2000 follow-up included over 12,000 completed cases with a weighted response rate of 82.71. The weight used for the analysis of data from the NELS:88/00 was WTN00, which includes students who entered postsecondary education.
