The data and analyses presented in this report are from the first (1980) wave of the National Center for Education Statistics (NCES) study, "High School and Beyond," a longitudinal study of U.S. high school seniors and sophomores. This study was conducted for NCES by the National Opinion Research Center at the University of Chicago. Information of several sorts was obtained in the survey. Students completed questionnaires of about one hour in length and took a battery of tests with a total testing time of about one and one-half hours. School officials completed questionnaires covering items of information about the schools. A sample of parents of sophomores and seniors (about 3600 for each cohort) was surveyed primarily for information on financing of postsecondary education. Finally, teachers gave their perceptions of specified characteristics of students in the sample whom they had had in class, to provide information beyond the students' own reports about themselves.
