After reviewing the research design, objectives, and basic conceptual model for the National Longitudinal Study of the High School Class of 1972 (NLS), this document describes the survey plan and issues for the third followup survey. Data analyses--both those that are in progress or planned--are summarized. These activities include composite score…

The National Longitudinal Study of the High School Class of 1972 obtained data for 23,451 students, of whom 16,683 completed the base-year questionnaire; 21,350 completed the first follow-up; and 20,872 completed the second follow-up.

The report traces the activities which led to the development of the adjusted weights--beginning with the basic National Longitudinal Study design, the base-year weight calculations, and the resurvey procedures. Next, the report describes the first follow-up weight calculations (including unadjusted student weights), nonresponse adjustment…

Part A of this report, briefly describes the…
