CIA Part 3 study guide

Part 3: Business Knowledge for Internal Auditing is the third of the three exam parts that make up the Certified Internal Auditor (CIA) credential, The IIA's global internal audit designation held by more than 220,000 professionals across 170 countries. It is aimed at candidates in the traditional CIA pathway who have applied and been approved into the program and who satisfy the education and experience requirements (or hold an active Internal Audit Practitioner designation). The IIA does not prescribe the order in which parts are taken, so Part 3 can be scheduled before, between, or after Parts 1 and 2. The part is a 100-question, two-hour computer-based exam delivered at secure test centers, covering the business knowledge an internal auditor needs to interpret organizational objectives, processes, and financial information; The IIA publishes the weighted topic percentages in the 2025 CIA syllabus rather than on its certification page. The CIA Part 3 study guide has 4 sections and about 1,210 words.
