The BOT advances the quality, relevance, and effectiveness of the ABR’s exams for Initial and Continuing Certification across all disciplines of radiology. The BOT makes recommendations to the Board of Governors regarding assessment structure including, but not limited to, exam format, content, assembly, delivery, scoring, and feedback. Members have specialty and subspecialty expertise, reflecting major areas of clinical practice.
