This supporting statement accompanied the first followup questionnaire for the National Longitudinal Study of the High School Class of 1972, when it was submitted for government clearance. The first part of the statement gives the background, uses, and justification of the survey; the largest part describes the plans for the first follow-up (survey procedures, reports and tabulations, schedule); the last part discusses consultations and meetings leading to the development of the first followup questionnaire and concerns about respondent burden, sensitivity, and confidentiality. The results of the Census Bureau pretest and copies of the instruments are appended. (Author/CP)
