This study investigated the effects of a short-term in-service training program for rehabilitation practitioners. Specifically, cognitive, attitudinal, and behavioral changes were measured. Also examined with respect to the observed changes were the effects of age, sex, education and other variables. Significant information gain was made by the participants of the training program in comparison with the control group. When the program participants reported their attitudes, no significant difference was found between them and the control group. Judging from the supervisors' ratings, the participants of the program seemed to benefit significantly in terms of information gained, attitudes changed, and placement behaviors exhibited. There was a significant positive correlation between the age of an individual and his or her positive attitude change. The higher the level of education of an individual, the more positive the attitude change that occurred, and the less the amount of dogmatism that was measured. Persons who had been trained in the nonhelping professions showed more positive attitude change than those who had been trained in the helping professions. The questionnaire, answered anonymously by the trainees, indicated that virtually all of them found the training program very worthwhile. When the trainees rated their own perceived change after the training program (on a scale of "none," "slight," "moderate," "much," or "great") the group averaged "moderate" or more change in information, attitude, and behavior, and "much" change in motivation. It was concluded that the training program was effective in advancing the academic achievement of the participants. Judging from the supervisors' ratings, participants benefited significantly in terms of professional growth. The participants were supportive to the training program and expressed the belief that it was of value.
