The study was conducted in Texas on a sample of 778 students to develop a process for administrative decision-making related to modifying or redirecting educational programs through collection and analysis of followup data obtained by questionnaires sent to former students. The document deals with a comparison of former students who took vocational courses and those who did not, when occupational choice occurred, and the effect of selected factors (academic/vocational courses, teachers, chance, etc.) on occupational choice. Opening sections of the document are devoted to a seven and one-half page review of literature and descriptions of the study's purpose, objectives, and its methodology. The major section of the document presents an analysis of data gathered from former vocational-technical students and non-vocational-technical students. Data related to student responses and hypotheses in the areas of job satisfaction, basic skills and technical knowledge, effectiveness of facilities and equipment, effectiveness of instructors, and personal services provided by high schools are tabulated and discussed. A summary, nine conclusions, and seven recommendations conclude the document. A suggested model for evaluating vocational-technical programs, a 38-item bibliography, and the questionnaire form are appended. (NH)
