The National Longitudinal Study of the High School Class of 1972 (NLS-72) collected data on a sample of seniors in the 1971-72 school year. Excluded were students from schools for the handicapped, schools for legally confined students, and special school situations. The school file, a companion to the student data file, contains 1,318 records, one for each high school from which NLS-72 students were sampled. It contains information about the environment, staff, procedures, facilities, and curricula of the sample high schools. The 504 variables of each record are primarily from the School Questionnaire and one or two Counselor Questionnaires from each school.
