CIA Part 2 Pass Rate, Format & Study Guide
A real reference for anyone preparing for the Certified Internal Auditor — Part 2: Practice of Internal Auditing exam — pass rate, retake policy, how it's scored, and a practical study timeline. This is independent reference content, not a sales page: everything below is sourced from CIA Part 2's own certifying body.
Pass rate
The certifying body does not publicly publish an official pass rate for this exam. Be wary of third-party sites citing a specific number here — treat any pass-rate claim you see elsewhere for this exam as unverified.
If you don't pass — retake policy
Same program-wide IIA policy as Part 1: a 30-day wait after a failed attempt, a fresh registration and exam-fee payment for each retake, and a cap of 8 attempts per exam part within your 3-year program eligibility window.
How it's scored
Part 2 uses the same scale-score system as the rest of the CIA program: a passing score of 600, set through The IIA's standard-setting process, applied consistently even though the specific cut score (in raw questions) varies part to part based on question difficulty. A failed attempt gets you domain-level performance feedback; a pass shows no numeric score.

How to actually prepare
Part 2 is 100 questions in 2 hours, and Performing the Engagement carries 40% of the exam — double the weight of any other domain (Managing the Internal Audit Activity, Planning the Engagement, and Communicating Results & Monitoring Progress are 20% each). Because Performing the Engagement is scenario-heavy (audit evidence, sampling, analysis techniques), prioritize practice questions that simulate mid-engagement judgment calls over rote recall, and budget the remaining even-weighted domains roughly equally rather than over-indexing on any one of them.
