Scoring and Results
Scoring
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 IN MEDICAL PHYSICS MUST PASS BOTH PARTS 1 and 2 OF THE EXAMINATION FOR ADMISSION TO THE ORAL EXAMINATION.
Part 1
Candidates who fail both portions of the Part 1 exam must repeat the entire Part 1 exam at the next annual exam.
Candidates who fail just the Clinical portion of Part 1 and pass the General portion can re-take the Clinical portion at the make-up exam if they have passed Part 2 on their current application. Candidates who are eligible for Part 1 only or who have not passed Part 2, must wait for the next annual exam.
Candidates who fail just the General portion of Part 1 must re-take the entire Part 1 exam at the next annual exam.
Part 2
Candidates who fail a Part 2 exam must re-take the Part 2 exam at the next annual exam.
Exam results are sent by U.S. Mail four to six 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 six weeks after the exam, you may contact the ABR office.
