Rationale and Objective. To organize and implement a mock oral examination for radiology residents in an attempt to prepare them for the American Board of Radiology Oral Examination. Materials and Methods. A mock oral examination was administered to junior and senior radiology residents by radiology faculty. All participants completed postexamination surveys. Results. The mock oral examination process not only provided practice for preboard residents, but also determined areas of deficiency in their fund of knowledge and presenting skills. Additionally, it provided faculty members with areas of curricular weakness. Conclusion. Administration of a mock oral examination reaps multiple benefits, which far exceed the task of its implementation. © AUR, 2005.
