When exams are scored, each question is analyzed by the psychometrics group of the American Board of Radiology. Any questions with unusual statistics are reviewed by subject-matter experts to verify that questions are unambiguous and keyed correctly (for example, questions that proved to be extremely difficult and questions that low-scoring candidates answered correctly more frequently than high-scoring candidates). The Difficulty for each question (the total percentage of examinees answering the question correctly) and the Discrimination for each question (how well a question discriminates between the upper and lower groups of examinees in the total exam) are also evaluated.

A statistical analysis of the total examination is prepared and evaluated, using a coefficient factor of reliability that judges the overall quality of the examination. Thus, it is possible to determine the degree of reliability of a given examination and to utilize this information in preparing subsequent examinations.

Candidates failing one or two components of the computer-based exam must repeat only the failed portion(s), either in the next annual examination or in an earlier make-up exam. Those candidates failing three components of the computer-based exam must repeat the entire computer-based exam.

After the examination is scored, the Board will send you notification of your results, including a quartile ranking in each of the separate categories within the Clinical portion of the examination.

To assist them in developing their programs, program directors and chairmen will receive this same information for all candidates from their programs.

Exam results are sent by U.S. Mail 4 to 6 weeks after the exams. In this time period do not request scores by e-mail, fax, or any other method. If you have not received your results within 6 weeks after the exam, you may contact the ABR office.
