Abstract: The College of Family Physicians of Canada uses a simulated office oral examination to test candidates for certification in family medicine. This examination has been highly successful. An analysis of this instrument provides a description of skills required for a certificant of the college. Its basic outline can be used to assess residents' interviewing skills during training and to help prepare them for practice.
