The Certified Internal Auditor (CIA) is the globally recognized internal audit credential from The Institute of Internal Auditors: three multiple-choice exam parts with published pass rates of roughly 44% (Part 1), 48% (Part 2), and 56% (Part 3), about $990 in member exam fees, and a scaled passing score of 600 on a 250 to 750 scale. It is the certification internal audit departments name in job postings the way public accounting names the CPA.
Internal auditors work inside an organization, assessing whether its governance, risk management, and controls actually work, and reporting what they find to management and the board. The CIA certifies that its holder knows how to do that job to the IIA's professional standards. Since January 2024 those standards are the Global Internal Audit Standards, organized into 5 domains and 15 principles, and the current exam syllabus is built directly on them.
The three exam parts
| Part | Name | Format | Published pass rate |
|---|---|---|---|
| Part 1 | Internal Audit Fundamentals | 125 questions, 2.5 hours | about 44% |
| Part 2 | Internal Audit Engagement | 100 questions, 2 hours | about 48% |
| Part 3 | Internal Audit Function | 100 questions, 2 hours | about 56% |
Part 1 covers the foundations: the purpose of internal auditing, the internal audit charter and mandate, independence and objectivity, ethics and professionalism, governance and risk concepts, and fraud risks. It carries the lowest pass rate and the most conceptual depth.
Part 2 covers running an engagement end to end: setting objectives and scope, assessing risks, building the work program, gathering and weighing evidence, documenting workpapers, and supervising the work. It is the most applied part, with scenario questions that ask what the auditor should do.
Part 3 covers managing the internal audit function itself: the risk-based audit plan, resources and operations, the quality assurance and improvement program, communicating results, and following up on management action plans.
All three parts are computer-based, offered on demand at Pearson VUE test centers year-round. There are no exam windows, so you schedule each part when you are ready.
What it costs
For IIA members, the traditional path costs about $990 in total: a $120 application fee, $310 for Part 1, and $280 each for Parts 2 and 3. Nonmembers pay about $1,515 for the same path. Commercial prep courses add roughly $500 to $850 on top (Gleim 2026 full-set pricing; UWorld and Becker run higher), which is why the total cost of becoming a CIA is usually quoted between $1,500 and $2,500.
That places the CIA among the most affordable major finance and audit credentials. The finance credential ROI map compares the full economics against the CPA, CFA, CMA, and the rest of the field.
Who the CIA is for
The CIA fits three groups particularly well. Working internal auditors who want the field's standard credential and the pay band that comes with it. External auditors and accountants moving in-house to internal audit, SOX, or controls roles, where the CIA is more directly on point than a second accounting license. And IT auditors and risk professionals who want a governance-and-controls credential recognized across industries and countries.
Average US internal auditor pay is about $102,000 (Indeed, 2026), with senior internal audit managers and directors reaching $160,000 and above (Robert Half 2026 Salary Guide). The credential requires 24 months of internal audit or equivalent experience with a bachelor's degree (12 months with a master's), verified at certification rather than before the exams.
