An integral component for the evaluation of resident's cognitive knowledge is the examination developed under the auspices of the Council on Resident Education in Obstetrics and Gynecology (CREOG). We sought to assess the usefulness of this annual examination from the perspective of both residents and residency program directors. We were particularly interested in comparing the contemporary use of this examination with the original intent of CREOG when the examination was developed in 1968. In addition, we were interested in determining the role of the examination in modifying educational programs. A questionnaire was mailed to all program directors before the 1994 examination and given to all house staff when the examination was administered. The response rate was 55 and 82%, respectively. Overall, the majority of residents (60%) and program directors (58%) found the examination to be an accurate assessment of cognitive knowledge; feedback on examination results varied widely, and residents used a variety of tools to prepare for the examination.
