The National Longitudinal Study of the High School Class of 1972 has completed two phases of data collection: the Base-Year and the First Follow-Up Surveys. This paper summarizes some of the findings from cross-sectional and longitudinal analyses of that data. A cross-sectional analysis of the base-year results yielded information on grades, work, factors interfering with study, job importance, extra-curricular activities, school evaluation, high school counseling services, study plans, financial aid plans, choice of college, and locus of control. Results from the first follow-up survey dealt with activity status in The fall fo 1973, marriage and family planning, educational expectations, life goals, reasons for not continuing education, type of post Secondary institution, full-time versus part-time study, field of study, satisfaction with post secondary education, job satisfaciton, and relevancy of high school job training. A longitudinal analysis yielded data describing the relationship of plan fulfillment to ability, socioeconomic status, race, sex, high school program, and geographic region. A further analysis described the effects of these variables on activity state transitions, or differences between October 1972 and October 1973 actitives. A model for evaluating financial aid data is also presented. (BW)
