The Institute of Internal Auditors study plan
CIA-1 study plan
A step-by-step CIA-1 study plan: the exact order to study in, how long to spend on each stage, and when to start practice questions. Follow it top to bottom.
The real CIA-1 is 125 questions in 150 minutes, pass mark 600 / 750 (scaled). For the full domain-by-domain breakdown behind each stage, read the CIA-1 study guide.
Your step-by-step plan
Map the outline and book a date
Day 1Read the official Part 1 exam outline and its four sections with their weights. Book a provisional exam date now: a fixed date turns open-ended study into a plan and is the single biggest predictor of actually sitting the exam.
Lock the foundations and independence (Section A)
Week 1This is the largest section and the base for everything else. Get the mandate of internal audit, the 2024 Global Internal Audit Standards, and the independence-versus-objectivity distinction solid before moving on. Use the recall prompts in this guide: cover the summary, answer from memory, then reveal.
Work through governance, risk, and control (Section C)
Weeks 1-2The second-largest section and the densest on precise pairs. Drill the Three Lines Model roles, inherent versus residual risk, appetite versus tolerance, control types, and design versus operating effectiveness with scenario questions rather than flashcards alone.
Cover ethics and professionalism (Section B)
Week 2Learn the four Code of Ethics principles by name and practise dilemmas where the right answer is to decline, disclose, or escalate. Anchor due professional care and professional scepticism as reasonable care and a questioning mind, not perfection.
Study fraud risks (Section D)
Week 3The smallest section but a reliable source of marks. Learn the fraud triangle, map red flags to its legs, keep internal audit's supporting role calibrated, and separate preventive from detective anti-fraud controls.
Practise on scenarios with every answer explained
Week 3-4Move to full practice sets and read the explanation for every question, including the ones you got right. Part 1 tests judgement between plausible options, so understanding why a distractor impairs independence or crosses a role line is where the marks are.
Find weak sections, then sit a timed mock
Week 4Use your per-section accuracy to drill the sections dragging you down rather than re-reading what you know. Then take at least one full timed mock to rehearse pacing and flag-and-return, and review every missed question before booking or sitting.

Frequently asked questions
How long does this CIA-1 study plan take?
It is 7 stages, paced by how much time you can give it each week - most candidates work through it in 2 to 6 weeks. Each stage below has a suggested duration; slow down on any stage where the recall checks in the study guide are not landing before moving on.
What order should I study CIA-1 in?
Follow the stages in order below. They are sequenced deliberately: foundational material first, then the domains weighted heaviest on the exam, then timed practice, with review passes built in rather than left to the end.
Do I need practice questions as part of this plan?
Yes. Reading alone does not surface what you have not actually learned. This plan builds in graded practice, and the full 297-question bank is free to use as you work through each stage.
Is this plan enough on its own, or do I need the full study guide too?
This page is the plan: what to do and in what order. The study guide adds the domain-by-domain breakdown, easy-to-confuse traps, and worked examples behind each stage - read it alongside this plan, not instead of it.
