The American Board of Radiology radiation oncology Maintenance of Certification Part 3 Modular Examination: Evaluation of the first administration.

Based on data obtained from clinical practice analysis (CPA) surveys performed in 2010 and 2013, and with input from its maintenance of certification (MOC) advisory committee, the American Board of Radiology (ABR) recognized that the changing nature of radiation oncology practice patterns warranted revisions of its MOC Part III cognitive examination. One significant revision was the introduction of a modular examination that allowed diplomates to select specific areas of clinical interest. The module-based items represented 30% (60 of 200) of total examination content.
