Examination Cut Score and Scoring
The Radiology Certifying Examination is also a criterion-referenced examination (see above). This simply means that examinees are measured against an absolute standard of minimum competency, and not based on the performance of others taking the examination. This minimum competency standard, also known as the “cut score”, is developed from the following steps.

  1. Items to be used on the examination are selected based on the content outline and examination specifications.
  2. Examination questions will be graded by at least 2 Examiners in a blinded manner using the scoring rubric. Additional examiners will be used to score questions in the event there is disparity with the initial scores.

Names of candidates who pass the Certifying Examination are referred to the ACVR Executive Council, upon which a majority vote of approval will confer Diplomate status upon successful candidates.

Failing candidates will receive a letter from the  Chair of the Examination Committee detailing specific areas of weakness and strengths to aid in their preparation for the next examination.
