Performance of Certification and Recertification Examinees on Multiple Choice Test Items: Does Physician Age Have an Impact?
The development of recertification programs (now referred to as Maintenance of Certification or MOC) by the members of the American Board of Medical Specialties provides the opportunity to study knowledge base across the professional lifespan of physicians. Research results to date are mixed with some studies finding negative associations between age and various measures of competency and others finding no or minimal relationships.



Four groups of multiple choice test items that were independently developed for certification and MOC examinations in psychiatry and neurology were administered to certification and MOC examinees within each specialty. Percent correct scores were calculated for each examinee. Differences between certification and MOC examinees were compared using unpaired t tests, and logistic regression was used to compare MOC and certification examinee performance on the common test items.



Except for the neurology certification test items that addressed basic neurology concepts, the performance of the certification and MOC examinees was similar. The differences in performance on individual test items did not consistently favor one group or the other and could not be attributed to any distinguishable content or format characteristics of those items.



The findings of this study are encouraging in that physicians who had recently completed residency training possessed clinical knowledge that was comparable to that of experienced physicians, and the experienced physicians' clinical knowledge was equivalent to that of recent residency graduates. The role testing can play in enhancing expertise is described.
