Differences in Physician Performance and Self-rated Confidence on High- and Low-Stakes Knowledge Assessments in Board Certification.

This novel study of physician certification suggests that the accuracy of physician performance increases with higher stakes, even as self-reported confidence in their knowledge declines. It suggests that physicians may be more engaged in higher-stakes compared with lower-stakes assessments. With medical knowledge growing exponentially, these analyses provide an example of the complementary roles of higher- and lower-stakes knowledge assessment in supporting physician learning during continuing specialty board certification.
