Copies of the survey instruments used in the base-year, first, second, and third followup studies of the National Longitudinal Study of the High School Class of 1972 (NLS) are contained in this publication. The instruments were used to gather data on the educational, vocational, and personal development of high school graduates, and the personal, familial, social, institutional, and cultural factors that contributed to that development. The Student Questionnaire used in the base-year survey elicited information about plans, operations, and experiences. The Student Test Book was used to measure verbal and nonverbal ability. The NLS School Questionnaire was designed to gather data on school characteristics and the NLS Counselor Questionnaire was developed for the collection of information on school guidance activities. The NLS School Record Information Form was designed for gathering selected data from respondents' records. The NLS Follow-up Questionnaires elicited data on the work and educational activities, experiences, attitudes, and plans of the respondents. Base-year instruments for individual respondents were self-administered in group situations; school forms were completed by administrators. All followup instruments were designed for individual self-administration after receipt by mail. Technical data resulting from these instruments are not included in this publication. (EVH)
