This study of elementary, middle, and high school counselors (N = 361) investigated the discrepancies, and the factors predictive of the discrepancies, between the actual practice and preferred practice in interventions associated with a comprehensive, developmental school counseling program. Results indicated that school counselors preferred to spend their time in accord with best practice. Subsequently, selected professional, employment, self-efficacy, and school climate variables were found to predict differences between actual and preferred practice.
