Based on many years of training students in both school and clinical psychology, the authors have formulated some impressions of differences and similarities found in these trainees. While generalizations remain tentative and call for research, the students in each of these disciplines seem to present different patterns in cognitive styles, perceptions of clients, conceptions of professional role, and personality characteristics. In personality, the students in these fields often display differences in need for structure, need for external support, social maturity, and desire for autonomous professional functioning. Differences seem to be related to variations in previous work and educational experiences, and to differences in age, sex and marital status. Implications for quality of service offered and training needs are outlined.
