Exam Scoring

The AOBIM sets passing standards for the Written Exam using a measurement model known as “criterion-referenced standard setting.” Using this model, the board specifies the particular content and level of content difficulty necessary to be considered a passing candidate. All examination results will be reviewed by the board. Results will be released electronically through the AOBIM’s application portal. Candidates must be program complete and maintain AOA membership in order to access electronic results.
