This CD-ROM presents data from the National Postsecondary Student Aid Studies (NPSAS) conducted in 1992-93, 1989-90, and 1986-87. Students who began their postsecondary education in 1989-90 were also surveyed in 1992 as part of the Beginning Postsecondary Students Longitudinal Study First Followup. The NPSAS is a comprehensive study that is examining how students and their families pay for postsecondary education. It includes nationally representative samples of undergraduates, graduates, and first-professional students, students attending less-than-two-year, two-year, four-year, and doctoral granting institutions. As a part of the 1993 NPSAS, information on more than 78,000 undergraduate and graduate students enrolled at any time during the 1992-93 school year was collected at about 1,100 postsecondary institutions. The sample represents students enrolled at any time between July 1, 1992--June 30, 1993. Major educational policy issues to be addressed by information collected during the study include: (1) how and why students continue their enrollment in postsecondary education; (2) how postsecondary education is financed; (3) what courses are taken and what grades and credits are earned; (4) fields of study pursued; (5) patterns of student transfers between colleges; (6) extent and timing of program completion; (7) attainment of degrees, licenses, or certificates; and (8) impact of postsecondary education on subsequent life experiences. An introductory file explains how to install the CD-ROM, limitations of the study, cautions about comparing data from the different years of the study, and additional information and restrictions on using and analyzing the data. A sampling of the variables included are: parents' contribution; parents' assets; parents' income; student's income; student's assets student's marital status; place of residence; grade point average; Social Security Benefits; medical and dental expenses; existing student loans; room and board; transportation; citizenship; degree expectations; expected date of degree; student attitude toward institution; student employment plans.
