CIA Part 3 Exam – Certified Internal Auditor Certification Guide

The official  CIA Part 3 exam is the third examination in The Institute of Internal Auditors (IIA) Certified Internal Auditor program. Under the updated 2025 CIA syllabus, Part 3 focuses on the Internal Audit Function, moving beyond isolated business, technology, and accounting concepts toward how an internal audit function is managed, planned, evaluated, and improved. The exam contains 100 multiple-choice questions and allows 120 minutes for completion. The IIA uses scaled scoring, with 600 required to pass. The current Part 3 examination fee is $280 USD for IIA members and $415 USD for non-members in the United States, Canada, and selected markets.

Certification Details

Fees can vary outside the United States, Canada, and selected markets because national institute agreements and applicable taxes may affect pricing.

Why This Certification Matters

The CIA certification demonstrates professional knowledge across internal auditing and provides an internationally recognized credential for professionals working with assurance, risk, governance, controls, compliance, and audit functions.

CIA Part 3 is particularly important because it evaluates how candidates understand the operation and management of an internal audit function.

Benefits include:

• Demonstrating knowledge of internal audit function management

• Strengthening professional credibility with employers and stakeholders

• Supporting progression into internal audit leadership roles

• Developing knowledge relevant to audit planning and quality management

• Demonstrating familiarity with engagement results and monitoring
