Learn more about Pearson VUE test delivery during COVID-19.



The mission of the American Board of Radiology (ABR) is to certify that our diplomates demonstrate the requisite knowledge, skill, and understanding of their disciplines to the benefit of patients. The ABR is offering initial certification and Maintenance of Certification (MOC) examinations in radiation oncology and medical physics as computer-based exams in Pearson VUE Professional Centers. The ABR is solely responsible for exam development, scoring, and reporting of results.

Pearson VUE testing tutorial and practice exam

Please Note: The tutorial explains the use of several types of items; however, ABR exams use only one-best-answer, multiple-choice questions. All other features demonstrated are applicable to ABR exams.

Exam Calculator Update (Applies to Medical Physicists ONLY)

You have two calculator choices for the Medical Physics Part 1 and Part 2 Exam (MP General and Clinical, MP Clinical only, MP Nuclear, MP Therapy, and MP Diagnostic Exams).

Medical Physics candidates taking the Part 1 and Part 2 exam may bring a Texas Instruments TI-30XS calculator with you. The calculator must be that specific model. Although Texas Instruments makes a variety of calculators, only the TI-30XS will be accepted.

If your calculator is not accepted or you choose not to bring one, an emulated version of the TI-30XS calculator will be available in the Pearson VUE exam interface. To familiarize yourself with its operation and the Pearson VUE exam interface, click the link above for the “Pearson VUE testing tutorial and practice exam." Please note that the calculator provided during the exam is a software program designed to emulate the handheld TI-30XS, not the actual handheld device itself.

Any notes, including manually programmed formulas, will not be allowed in the testing area. If the calculator has notes and/or formulas printed on it, or includes any other information, it must be removed or covered by solid colored tape. Calculators are subject to inspection by test center staff. Please leave all calculator cases and sliding covers in your locker as they will not be admitted into the testing center.

Again, if your calculator is not admitted for any reason the emulated version of the TI-30XS is embedded in to the testing software.

As has always been the case, absolutely no other personal electronic, computing, or calculator devices are permitted in the exam areas.
