The Institute of Internal Auditors study plan
CIA-3 study plan
A step-by-step CIA-3 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-3 is 100 questions in 120 minutes, pass mark 600 / 750 (scaled). For the full domain-by-domain breakdown behind each stage, read the CIA-3 study guide.
Your step-by-step plan
Map the syllabus and set a date
Day 1Read the official Part 3 exam syllabus and the four sections with their weights, and confirm you are working from the current Internal Audit Function outline, not the retired 2019 Business Knowledge one. Book a provisional exam date now: a fixed date turns open-ended study into a plan.
Lock the function-management model (Internal Audit Operations)
Week 1Get the reporting model, strategy, and resourcing solid first, because the later sections assume the chief audit executive's reporting lines. Use the recall prompts in this guide: cover the summary, answer from memory, then reveal. Be able to name the correct party and sequence out loud.
Build the plan and secure quality (Internal Audit Plan and Quality)
Weeks 1-2Master the audit universe versus audit plan boundary and the dynamic, risk-based nature of the plan, then the quality assurance and improvement program with its internal versus external assessment distinction. These two sections are smaller but dense with traps, so drill the confusable pairs.
Go deep on engagement results and monitoring
Weeks 2-3This section carries the most weight, so spend the bulk of your time here: the seven communication attributes, recommendations versus action plans, residual risk and risk acceptance, and the follow-up and escalation sequence. Use scenario questions, not definitions alone.
Practise on scenarios with every answer explained
Week 3Move to full practice sets and read the explanation for every question, including the ones you got right. Part 3 tests the single best next action among plausible options, so understanding why a second-best answer is still wrong is where the marks are.
Find and close your weak sections
Week 4Use your per-section accuracy to drill the areas dragging you down rather than re-reading what you already know. Repeat until every section clears the pass line with margin on unseen questions.
Sit a timed mock and review it
Week 4Take at least one full timed mock to rehearse pacing and flag-and-return. Treat the score as a per-section readiness signal, then review every missed question before booking or sitting.

Frequently asked questions
How long does this CIA-3 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-3 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 316-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.
