Exam Scoring and Results

Last verified on January 24, 2023
The ABR uses criterion-referenced scoring on all its computer-based exams. To learn more about this method and how it differs from norm-referenced scoring, please visit our Exam Scoring Model page.
Candidates failing any part of the computer-based Qualifying Exam must repeat only the failed part(s) in the next annual exam. Those candidates failing all three parts must repeat all of them.
After the exam is scored, the Board will send each candidate notification of his or her results, including a quartile ranking in each of the separate categories within the clinical portion of the exam.
To assist them in monitoring their programs, program directors and department chairs will receive the same information for all candidates from their programs.
Initial Qualifying Exam results are posted in each candidate’s myABR account approximately one month after the exam. Candidates will receive an email when results have been posted. “Next steps” letters and performance reports also will be received within three weeks after the results are posted to myABR.

During this time, please do not request scores by email, fax, or any other method. Candidates who have not received their results within one month after the exam may contact the ABR office.
