In the spring of 1984, the San Diego (California) Unified School District's Research Department initiated a five-year study of the district's 1984 senior high school graduates. The study documents graduates' transition from high school into young adulthood, beginning shortly after graduation. Focus is on: (1) providing information to district staff and the general public regarding graduates' progress and the degree to which the San Diego City Schools have prepared graduates' for life after high school; and (2) assisting district staff in evaluating and reviewing current programs and services through the use of information about graduates' assessments and experiences. Study subjects, selected via proportional, stratified random sampling, were administered questionnaires by mail; non-respondents were contacted by telephone. Approximately 74% of the targeted students responded (N=759). Results cover employment rates and occupations, wages, postsecondary educational aspirations and enrollment, marital status, attitudes toward high school experience, parental influences, and differences in student responses that could be attributed to racial or ethnic group membership. Recommendations based on findings are largely directed toward counseling requirements, the needs of Hispanics and Blacks, and the importance of inclusion of basic skills in high school curricula. Sixty-three tables and 48 graphs are presented; and the August and September 1986 Graduate Follow-Up Questionnaires and Graduate Follow-Up Telephone Script are appended. (TJH)
