In May 2016, the ABR announced its plan to move away from the traditional 10-year MOC exam, administered in ABR exam centers, to Online Longitudinal Assessment, or OLA (for more information see the Part 3 page). The traditional MOC Exam described below is needed only in limited situations. You can determine your need to take the MOC Exam by logging in to myABR. If you still have questions about whether or not you need to take the MOC Exam, please call (520) 790-2900 or send an email to
The ABR’s MOC exam for medical physicists is a computer-based, proctored exam administered at Pearson VUE Test Centers. The exam is multiple-choice format and covers core knowledge (approximately 30 percent) and current evolving technologies (approximately 70 percent). Multiple certificate holders must complete the exam for each discipline in which they hold a certificate.
