This study compares selected in-school characteristics found to be significantly related to in-school success, to on-the-job success as measured by the employer's evaluation. Subjects were male high school graduates of both academic and vocational curricula who were actively employed approximately one year after graduation. The research questions in this study are concerned with a comparison of job satisfactoriness (success as rated by the employer) for vocational and academic high school graduates, and the relationship of ninth grade student characteristics to job satisfactoriness approximately one year after graduation. Results indicate, in part, that: (1) neither the academic nor the vocational curriculum can be said to better prepare male graduates for employment one year after high school based on the employer's evaluation; (2) the male graduate's verbal and numerical aptitude, and the salary received are most predictive of on-the-job success; (3) all of the factors related to on-the-job success were also related to in-school success; (4) the ability of ninth grade characteristics to predict on-the-job success as defined in this study is of significant magnitude.
