About this exam

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. Study materials are not included with an application or exam registration - The IIA directs candidates to the syllabus, retired-question practice sets with rationales (two attempts each), and its Becker review course. Registration stays valid for 180 days, testing runs in February, June, September, and November, and official results arrive within three weeks. Part 3 costs $280 for members and $415 for non-members, with pricing changing on 4 January 2027.

What you'll study

Common questions

About CIA Part 3 preparation

What is the format and length of the CIA Part 3 exam?

Part 3 is a computer-based, multiple-choice exam of 100 questions with a time limit of 2 hours (120 minutes). It is delivered at global test centers operated with Pearson VUE, which the IIA describes as offering secure, computer-based testing. Parts 1 and 2 are longer and shorter respectively: Part 1 has 125 questions in 2.5 hours, Part 2 has 100 questions in 2 hours.

Do I have to pass Part 3 in order, after Parts 1 and 2?

No. The IIA states that it does not prescribe the order in which to take the exams and advises candidates to review the syllabi to decide what is appropriate for them. Many candidates sit Part 3 first or in the middle of the sequence, depending on their background and study timeline.

How much does the Part 3 exam cost?

The CIA part 3 exam is $280 USD for members and $415 USD for non-members, a member saving of $135. The IIA warns that pricing will change starting 4 January 2027 and that updated amounts are published separately. All fees are non-refundable and non-transferable, and taxes or National Institute pricing may apply outside the United States, Canada, and select countries.

How long do I have to sit the exam after paying for it?

Exam registrations are valid for 180 days, or until your certification program expiration date, whichever is sooner. If you do not sit for your exam during that registration period, the registration is forfeited. Because Part 3 requires you to register, schedule, and sit within that window, plan your study time around it rather than buying the registration too early.

When can I actually take the exam during the year?

Testing windows are February, June, September, and November. Once you have purchased an exam registration, you have 180 days to register, schedule, and sit for the exam, so the practical constraint is matching your window to one of those four months within your registration period.

How quickly will I get my Part 3 score, and how am I notified?

You receive a single, official exam result within three weeks of your exam date. When results become available, The IIA sends a system-generated email notification. Test centers do not hand out pass or fail results at the end of the session, so budget about three weeks before you know the outcome.

How much time do I have to finish the whole CIA program?

You have three years to complete the requirements of the CIA program, counted from the date you are accepted, and all three exam parts must be passed within three years of applying. Candidates who already hold an active Internal Audit Practitioner designation receive a waiver for Part 1 and must pass Parts 2 and 3 within three years.

Are study materials included when I register for Part 3?

No. The IIA states that study materials are not included with the CIA application or registration. What is available separately includes the 2025 CIA syllabus, IIA practice questions drawn from retired exam questions with rationales for correct and incorrect answers and a maximum of two attempts per practice examination, and the Becker CIA review course.

In what languages can I take Part 3?

The CIA exam is offered in Arabic, Simplified Chinese, Traditional Chinese, English, French, German, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, and Turkish. Arabic is available for the 2019 syllabus through 27 December 2026 and moves to the 2025 syllabus on 28 December 2026; Simplified Chinese is only available in mainland China. From 28 August 2026 candidates may register in Vietnamese.

What if I fail - how do retakes work?

The public CIA certification page does not state a retake waiting period or retake fee, so treat any specific number you hear as unverified. The IIA points candidates to the Certification Candidate Handbook, which covers the policies and procedures along the certification journey, for the authoritative rules on scheduling and re-sitting an exam part.
