The passing score for the Certified Internal Auditor (CIA) exam is 600 out of 750 points. This applies to all three parts of the exam.
While this score might seem equivalent to an 80% passing rate, it is important to remember that the exam is scaled. This means that the passing score is determined based on the difficulty of the exam, and the number of questions answered correctly relative to other test takers.
The Institute of Internal Auditors (IIA) sets the passing score, which is not publicly disclosed. However, you need to achieve a score of 600 or higher to pass each individual part of the exam.
