Passing the CIC is far more about structured preparation than raw knowledge. The exam is broad — spanning surveillance, transmission, sterilisation, occupational health, leadership and more — so candidates who fail usually studied unevenly rather than badly. This guide gives you a clear map of what's tested and a realistic, week-by-week plan you can run alongside a demanding infection-control job.
If you're still deciding whether you're eligible to sit, start with our CIC eligibility guide; this article assumes you've committed and want a plan.
Know the exam you're preparing for
The CIC is 150 multiple-choice questions (135 scored, 15 unscored) over 3 hours, split into two 90-minute sections with an optional break, and it uses a scaled pass mark of 700 (on a 300–900 scale). One feature shapes your whole strategy: since 2025 the exam is forward-navigation only — you can't skip a question or go back. That means you must build the habit of deciding and committing on each question, because there's no coming back to it.
The domains — and how to prioritise them
CBIC organises the exam around the core areas of IPC practice. Confirm the current content outline on the CBIC website, but broadly expect:
| Domain | What to master | Focus |
|---|---|---|
| Identification of infectious disease | Pathogens, transmission routes, HAIs | High |
| Surveillance & epidemiology | Definitions, rates, data, outbreak investigation | High |
| Prevention & transmission control | Precautions, isolation, bundles, hand hygiene | High |
| Cleaning, sterilisation & disinfection | Reprocessing, Spaulding classification, asepsis | Medium |
| Occupational / employee health | Exposures, immunisation, post-exposure follow-up | Medium |
| Management & leadership | Programme evaluation, communication, policy | Medium |
| Education & research | Teaching, evidence, guidelines | Lower |
| Environment of care | Construction, water, ventilation, waste | Lower |
Surveillance, transmission prevention and pathogen knowledge carry the most questions and are where scenario items concentrate, so they anchor the plan below.
The 8-week CIC study plan
This plan assumes 6–8 hours of study per week. Compress it if you have more time; stretch it if less. The sequence matters more than the calendar.
Weeks 1–2 · Microbiology and disease processes
Start with the foundations: pathogens, chains of infection, transmission routes and the major healthcare-associated infections (CLABSI, CAUTI, SSI, VAP, C. difficile). Everything else builds on this. End week 2 with a short diagnostic quiz to find weak spots.
Weeks 3–4 · Surveillance and epidemiology
Master definitions, rates and ratios, data interpretation, and outbreak investigation steps. This is heavily tested and often where clinical staff are weakest, so give it real time and lots of practice questions.
Weeks 5–6 · Prevention, transmission and reprocessing
Cover standard and transmission-based precautions, isolation, prevention bundles, hand hygiene, and cleaning/disinfection/sterilisation (including the Spaulding classification and asepsis). Connect each concept to your own facility's practice to make it stick.
Week 7 · Occupational health, leadership and environment
Round out exposure management and immunisation, programme management and communication, education, and environment-of-care topics (water, ventilation, construction, waste). These carry fewer questions, so aim for solid familiarity.
Week 8 · Full practice exams and review
Sit at least two full-length, timed practice exams — ideally practising the forward-only discipline of committing to each answer. Review every question you get wrong, and every one you guessed, and turn them into a one-page list of personal weak spots to reread the night before.
You're ready when you're consistently scoring comfortably above passing on fresh practice exams — not when you've simply finished the material.
Five tips that move the needle
- Practise forward-only. Train to commit to each answer, since the real exam won't let you go back.
- Do questions from day one — they teach the exam's logic faster than reading does.
- Anchor theory to your workplace — real examples from your facility stick far better.
- Study the reasoning, not the answer — know why the right option is right and the others wrong.
- Spend time where you're weak, especially surveillance and epidemiology, not where you're comfortable.

Why candidates fail — and how to avoid it
- Weak on surveillance and epidemiology. It's heavily tested and often the least comfortable area for clinical staff. Fix: give it extra time and practice.
- Not practising forward-only. Freezing on hard questions wastes time you can't recover. Fix: rehearse committing and moving on.
- Reading instead of doing questions. Passive review feels productive but builds little exam judgement. Fix: questions from week one.
- Ignoring the current content outline. CBIC updates it; preparing from an old one leaves blind spots. Fix: check cbic.org.
- Cramming. The material is too broad to absorb in a week. Fix: spread study across the plan.
Exam-day logistics and tips
Small logistics protect months of study. If you test remotely via ProProctor, set up a quiet, private room with a clear desk and a stable connection the day before, and be ready to show the room to the proctor. If you test at a Prometric centre, arrive early with the correct government photo ID matching your application. During the exam, watch the clock across the two 90-minute sections, use the optional break to reset, and — because navigation is forward-only — answer every question as you reach it, making your best decision and moving on rather than agonising.
Frequently Asked Questions
How many questions are on the CIC exam?
150 multiple-choice questions in total — 135 scored and 15 unscored pretest items — over 3 hours, split into two 90-minute sections.
What score do I need to pass the CIC?
A scaled score of 700, on a scale that runs from 300 to 900.
Can I skip questions on the CIC exam?
No. Since 2025 the CIC uses forward-only navigation, so you must answer each question before moving on and cannot return to earlier ones.
How long should I study for the CIC?
Most candidates invest 50–80 hours — around 6–8 hours a week over 8 weeks — with extra time for weaker areas like surveillance and epidemiology.
