CIA Part 3 (Internal Audit Function) eligibility is shared across the entire three-part CIA program, not set separately per part: candidates need a bachelor's degree plus two years of internal audit experience (or a master's degree plus one year, among other qualifying pathways), a signed character reference attesting to professional conduct, and proof of identification, all submitted through The IIA's certification system. The CIA program application fee is $120 for IIA members and $240 for non-members, and the Part 3 exam fee itself is $280 for members and $415 for non-members. Part 3 consists of 100 multiple-choice questions administered over a 2-hour (120-minute) time limit, covering Engagement Results and Monitoring (45%), Internal Audit Operations (25%), Internal Audit Plan (15%), and Quality of the Internal Audit Function (15%) — following The IIA's 2025 syllabus realignment to the Global Internal Audit Standards.
