Two high school classes, from each of five high schools, separated by five years in time of graduation, are studied and analyzed in depth. Their educational and employment activities as well as selected attitudes towards the high school experience are reported in abundant detail. The research method used was stratified sampling. The crucial question was whether a stratum is related to the post-graduation activity or attitude of students. The graduate's sex, race, high school program, and grade-point average were found to be most germane to the survey's purpose. A statistical description of the class of 1973 is followed by statistical data on the graduates in such areas as: educational and occupational activity a year later; type of education institution attending; educational goals; employment situation and attitude; usefulness of high school courses in present activity; person most helpful in planning for the future; the value of membership in extra-curricular activities; the helpfulness of high school in learning selected skills; evaluations of instructors and counselors. Similar data is then presented for the class of 1969. Brief remarks clarify tables of data; there is no comparison of the two groups, and no summarization or conclusion. (AJ)
