The Naitonal Education Longitudinal Study of 1988

The National Postsecondary Student Aid Study (NPSAS) is a comprehensive nationwide study conducted by the U.S. Department of Education's National Center for Education Statistics (NCES) to determine how students and their families pay for postsecondary education.1 It also describes demographic and other characteristics of students enrolled in the 50 states, the District of Columbia, and Puerto Rico. The NPSAS study is based on a nationally representative sample of all students in postsecondary education institutions, including undergraduate, graduate, and first-professional students. Information is collected from institutions, student interviews, and government data files. For this study, data were analyzed for undergraduates from the 2000 administration of the NPSAS survey. This survey represents more than 16 million undergraduates who were enrolled at some point between July 1 and June 30 of the survey year. The institutional weighted response rate for this NPSAS administration exceeded 85 percent as discussed in the next sections. This report included only students who attended one institution during the 1999–2000 academic year, representing 95 percent of independent and 93 percent of dependent undergraduates.
