This paper proposes that the American Psychological Association establish a standard model of training for doctoral programs in clinical psychology requiring a specific number of credits, along with specific course recommendations appropriate for practice in the 21st century. This model should reflect the impact of psychology on the biological bases of behavior, require students to gain psychotherapy skills prior to test administration skills, and have internship experience occur after awarding of the Ph.D. The author recommends that the Ph.D. in clinical psychology consist of 4 years of study, encompassing 96 credit hours consisting of nine credits each in the biological bases of behavior, the cognitive-affective bases of behavior, and the social bases of behavior; and six credits in individual behavior. In the area of clinical psychology 63 credits are recommended with 12 credits for completion of a dissertation. Specific course recommendations include three credits each in research design, multivariate analysis, interviewing skills, psychotherapy systems theory, psychotherapy in a community placement, individual assessment (six credits), personality assessment (six credits), adult assessment, child assessment, psychopathology (six credits), ethics, supervision and administration of psychology services; and two supervised practica in clinical psychopharmacology.
