Competency-based education (CBE) is a model that guides the educational process toward acquisition of the knowledge, skills, and attitudes needed for effective professional practice in service of the public. Increasingly adopted by medicine and other professions, the CBE model involves establishing competency goals, developing curricula and other experiences designed to help students reach these goals, integrating instruction in the full range of competencies throughout the educational sequence, guiding and evaluating student learning through ongoing assessment of competence, and revising courses and activities in hght of student competence outcomes. Included in a full CBE model are attention to unintended learning outcomes (the "hidden curriculum") and to areas not covered (the "null curriculum"), and efforts to promote education based on individual student learning trajectories as opposed to set courses or number of hours. Within professional psychology, we suggest that APA accreditation is aligned with a version of the CBE model; and significant progress has been made in identifying and measuring professional competencies. However, these are merely tools that can help training programs implement a broader CBE educational model that we contend has not been widely realized in professional psychology. This article reviews CBE and its application in medicine, discusses the benefits and criticisms of CBE, and considers what a fuller realization of CBE would look like in professional psychology training programs, including graduate programs, practicum, internships, and postdoctoral settings.In recent years, the time-honored processes of doctoral education and training in the health professions have been challenged by a new model known as competency-based education, or CBE. This model has greatly affected education in a number of professions, including medicine and dentistry (Chambers, 1993;Frank et al.,
