Exam Scoring

Scoring Criteria

AOA reports candidates’ certification results using standardized scaled scores. Scaled scores are more valid and reliable compared to raw scores and make scores comparable across different forms of the exam. The AOA reports scores on a 200 to 800-point scale with a scaled score of 500 or higher required to pass.

  • A scaled score of 500 represents the minimum level of knowledge and skill necessary to pass the exam as established by AOA Certifying Boards.
  • The highest possible scaled score is 800.
  • The lowest possible scaled score is 200.
  • Overall scores are based on the total number of items answered correctly, regardless of content area.

Results by Content Area

  • When possible, a breakdown of exam scores by content area is provided to help you identify your areas of strength and areas that may need more development.
  • The number of items for each content area indicates the relative amount of test questions on the exam for that content area.
  • Content area scores are not weighted to calculate your overall score; each content area is scored separately after the overall analysis is complete.

.

Exam Failure

Following an initial or second failure of the AOBS Written Exam, the following rules apply:

  • The candidate may apply for re-examination and pay the required fees.
  • The candidate must re-take the exam within a two-year period following the initial or second failure. If the candidate fails to take the exam within this period, the candidate’s file will be considered inactive. Any further applications shall be considered new actions at the discretion of the board.

Following a third failure in the written qualifying and/or oral certifying examination, the candidate may apply for reexamination upon successful completion of a board review course. The applicant must provide documentation of course completion prior to retaking the written examination. Remediation does not guarantee passage of the examination process.
