The goal of the Certified Internal Auditor® (CIA®) exam is to confirm that aspiring candidates have the skills required to meet the industry’s standards. CIAs need to be equipped with the skills and know-how to perform their tasks, so the CIA exam is divided into three parts that test a broad range of topics. Aspiring CIA candidates will need to sit for and pass each of these three parts of the CIA exam individually.
Here’s a summary of the exam parts and topics tested. Further down, we’ll guide you through each part of the CIA exam by breaking down the content tested in each category and subcategory.
35% – Foundations of Internal Auditing
20% – Ethics and Professionalism
30% – Governance, Risk Management, and Control
15% – Fraud Risks
50% – Engagement Planning
40% – Information Gathering, Analysis, and Evaluation
10% – Engagement Supervision and Communication
25% – Internal Audit Operations

Each of the three CIA exam parts tests different topics using multiple-choice questions. There are no essays or free-response questions on the exam.
Candidates have reported that the CIA exam can be tricky and give two very similar answer choices. Always select the best or most correct answer out of the provided options, and if you’re ever in doubt, make your best educated guess.
The CIA exam is non-disclosed, meaning the questions on it aren’t available to anyone, including professional review courses like Gleim.
There is a large body of questions that each exam pulls from, meaning no two exams will be exactly the same. The specific number of questions from each topic gets slightly randomized, so it’s important to prepare for all the possible topics that could be on the CIA exam.

125 multiple-choice questions
2.5 hours long
CIA Part 2

The Institute of Internal Auditors® (IIA®) regularly conducts studies in professional environments to understand the responsibilities and expectations of CIAs. This research then informs the CIA exam syllabus, which details what candidates are expected to know and how well they’re expected to know it.
Each CIA exam part consists of high-level categories called “sections” in the exam syllabus. These categories are divided into subcategories that contain detailed objectives that candidates must perform to pass the CIA exam.
Regardless of which part of the CIA exam you’re taking, there are a few considerations that apply to all of them.

Although CIA candidates can take the exam in any order, at Gleim, we recommend that most people take the exam in sequential order. Topics in each part build on the previous one, which means that mastering Part 1 will prepare you for Part 2, and mastering Parts 1 and 2 will help you prepare for Part 3.
One notable exception exists for recent graduates. Part 3 tests candidates on topics they need to have professional awareness of, rather than practical knowledge they will use in their everyday tasks. Therefore, many people find CIA Part 3 easier to take while the curriculum is still fresh in their minds.
If you’re not a recent graduate, you’re still welcome to take the exams in any order, but pay close attention to what’s tested on each part to make sure you’re prepared!
