Can You Choose Which CIA Part to Take First?

Yes. The Institute of Internal Auditors (IIA) allows candidates to take CIA Part 1, Part 2, and Part 3 in any order. There is no prerequisite requirement — you do not need to pass Part 1 before registering for Part 2 or Part 3.

This flexibility exists because each part tests a distinct body of knowledge. However, just because you can take them in any order does not mean every order is equally effective. The sequence you choose directly affects how efficiently you study and how likely you are to pass each part on the first attempt.

For full details on how to register and schedule your exam parts, see our step-by-step CIA registration guide for 2026.

The Recommended Order: Part 1 → Part 2 → Part 3

The majority of CIA review providers, IIA educators, and successful candidates recommend taking the exam in numerical order. Here is why this sequence works best for most people:

This is the order we recommend in our complete CIA study plan for 2026.

Why Part 1 Should Come First

CIA Part 1 — Internal Audit Fundamentals — is structured as the entry point to the profession. Under the 2025 syllabus, it covers four domains:

• Domain 1: Foundations of Internal Auditing (35%) — IPPF, GIAS 2024, IIA Mission, Definition of Internal Auditing. See our Domain 1 study guide.
• Domain 2: Ethics and Professionalism (20%) — IIA Code of Ethics, professional scepticism, due professional care
• Domain 3: Governance, Risk Management, and Control (30%) — COSO framework, Three Lines Model, risk assessment
• Domain 4: Fraud Risks (15%) — fraud triangle, fraud risk assessment, AI-enabled fraud

Every concept in Part 2 (engagement planning, fieldwork, communication) and Part 3 (managing the audit function, quality, strategy) builds on the standards, ethics, and governance framework you learn in Part 1. Starting with Part 2 or Part 3 means you are learning application without the foundational theory.

For a detailed study schedule, see our 12-week CIA Part 1 study plan for working professionals.

Why Part 3 Should Come Last

CIA Part 3 is widely regarded as the hardest part of the CIA exam. Under the 2025 syllabus, it covers four domains with the broadest range of subject matter:

• Internal Audit Operations (25%) — managing the audit function, resource allocation, technology
• Internal Audit Plan (15%) — risk-based audit planning, strategic alignment
• Quality of the Internal Audit Function (15%) — quality assurance, improvement programmes
• Engagement Results and Monitoring (45%) — communication of results, monitoring, follow-up

The breadth of Part 3 — spanning IT controls, financial management, data analytics, and strategic governance — means candidates need more study time and benefit from the confidence built by passing Parts 1 and 2 first.

For Part 3 strategies, see our How to Study for CIA Part 3: Risk, IT, and Analytics guide.

The global CIA exam pass rate ranges between 40–50% per part, with Part 3 historically having the lowest pass rate. Saving Part 3 for last means you approach it with exam-taking experience and stronger foundational knowledge.

When an Alternative Order Makes Sense

While Part 1 → Part 2 → Part 3 is the default recommendation, there are specific situations where a different order may work:

Start with Part 3 if:

• You have a strong background in IT audit, information security, or financial management
• You hold CISA, CPA, or CMA credentials and are already comfortable with the technical content
• You want to tackle the hardest part while your study motivation is highest

Start with Part 2 if:

• You are an experienced internal auditor who performs engagements daily
• You are very comfortable with audit planning, fieldwork, and reporting processes
• You want to leverage practical experience before studying theory

One order to avoid:

Do not start with Part 3 and leave Part 1 for last. Part 1 contains the standards and ethical framework that the IIA expects every CIA to know first. Candidates who skip Part 1 often struggle with Part 2 and Part 3 questions that reference GIAS principles or IPPF concepts.

If you hold a CA, CPA, or ACCA qualification and want an accelerated path, consider the CIA Challenge Exam — a single 150-question exam covering all three parts.

Timeline and Scheduling Strategy

Your CIA programme window is three years from the date the IIA approves your application. Within that window, you must pass all three parts. Here is a realistic timeline for working professionals taking the exam in sequential order:

Total timeline: 9–14 months for all three parts, studying 10–15 hours per week.

Note: Under the new 2026 scoring process, you will wait up to three weeks for your official result by email. Plan your study schedule to begin the next part immediately rather than waiting idle.

For full fee breakdowns, budget approximately $990 (IIA member) to $1,515 (non-member) for all three parts plus the application fee.

Frequently Asked Questions

Can I take CIA Part 2 before Part 1?

Yes. The IIA allows you to take CIA Parts 1, 2, and 3 in any order. However, Part 1 covers foundational standards and ethics that Part 2 questions assume you understand, so most candidates find the sequential order more efficient.

Which CIA part should I take first if I have audit experience?

Even with audit experience, starting with Part 1 is recommended. Part 1 tests the formal IPPF framework, GIAS 2024, and IIA-specific definitions that differ from day-to-day practice. Your experience will help you learn faster, but you still need the theoretical grounding.

Is CIA Part 3 really the hardest?

For most candidates, yes. Part 3 covers the broadest range of topics — IT, finance, operations, strategy, and quality management. The global pass rate for Part 3 is historically the lowest of the three parts. For strategies, see our CIA exam difficulty guide.

How long do I have to pass all three CIA parts?

You have three years from the date the IIA approves your CIA programme application. This window applies regardless of which part you take first. If you do not pass all three parts within three years, you must reapply and repay the application fee.

Should I wait for Part 1 results before studying for Part 2?

No. Under the new 2026 scoring process, results take up to three weeks. Begin Part 2 preparation immediately after sitting Part 1. If you did not pass Part 1, the Part 2 knowledge still reinforces your understanding and is not wasted.

What is the best CIA review course for all three parts?

Surgent CIA Review covers all three parts with adaptive AI and is available at India pricing (₹20,909) through Eduyush. Gleim has the largest question bank (3,500+ MCQs) and is the most recommended on Reddit. Both are strong choices.

Can CPA or CA holders skip directly to all three parts at once?

Qualified CPAs, CAs, and ACCA holders may be eligible for the CIA Challenge Exam — a single 150-question exam that covers content from all three parts. This is faster but requires preparation across the full syllabus.
