How to Pass the CIC Exam: A Study Guide and 10-Week Plan
In this article
To pass the CBIC Certified in Infection Control (CIC®) exam you need a scaled score of 700 across 135 scored questions from 8 domains. Most working infection preventionists prepare in 8–12 weeks, studying the three biggest domains first and finishing with a full timed practice exam. This guide gives you a 10-week plan built on the CBIC outline.

How long should I study for the CIC exam?

Plan 8–12 weeks at 5–7 hours a week if you already work in IPC. Give yourself longer if your role covers only some domains — for example, if you have never run surveillance or worked with sterile processing.

What should I study first?

Start with the three domains that carry 66 of the 135 scored items: identification of infectious disease processes, surveillance and epidemiologic investigation, and preventing transmission. Then cover sterilization (18 items under the current outline) before the smaller domains.

The 10-week CIC study plan

  1. <strong>Weeks 1–2 — Identification of infectious disease processes (22 items).</strong> Microbiology basics, interpreting lab results, common healthcare-associated infections.
  2. <strong>Week 3 — Surveillance and epidemiologic investigation (22).</strong> Surveillance definitions, rates and ratios, outbreak investigation steps.
  3. <strong>Week 4 — Preventing/controlling transmission (22).</strong> Standard and transmission-based precautions, hand hygiene, antimicrobial stewardship, immunization.
  4. <strong>Week 5 — Cleaning, disinfection and sterilization (18).</strong> Spaulding classification, high-level disinfection, sterilization monitoring, reprocessing failures.
  5. <strong>Week 6 — Environment of care (14) and employee health (11).</strong> Construction risk assessment, water and air, exposure management, staff immunization.
  6. <strong>Week 7 — Management and communication (14) and education and research (12).</strong> Program planning, reporting, adult learning, reading studies.
  7. <strong>Week 8 — Practice by domain.</strong> 20–30 questions per domain; log every mistake by domain.
  8. <strong>Week 9 — Full timed mock.</strong> 150 questions, two 90-minute blocks, forward-only.
  9. <strong>Week 10 — Close the gaps.</strong> Rewatch lessons for your two weakest domains; light review the last 2 days.
Sitting the exam in 2027 on the new outline? Move one extra week to education, research and program management, which gain 5 items. See the 2026 outline changes.

How does forward-only navigation change my strategy?

Since January 2, 2025, you cannot skip, flag or return to questions. Answer every question when you see it, using elimination, and keep moving. You have about 72 seconds per question (180 minutes ÷ 150), so don't spend 3 minutes on one item you can't change later. Practise in this mode before exam day.

Which CIC study resources should I use?

ResourceUse it for
CBIC candidate handbook and content outlineThe official list of what is tested
APIC Text (APIC's reference)The core reference most candidates study from
CDC and WHO infection prevention guidelinesPrecautions, disinfection, sterilization standards
Practice questions written to the CBIC domainsTiming and question style
CIC Exam Prep CourseA structured route through all 8 domains with exam-style practice
Watch for wrong-exam results: many "CIC practice tests" online are for the AAPC Certified Inpatient Coder exam. Check that questions cover infection prevention. Try our CIC practice questions written to the CBIC domains.

Exam-day tips

  • Bring a valid photo ID that matches your CBIC application.
  • Use the optional 16-minute break between sections.
  • Testing online with ProProctor? Run the system check days before and prepare a clear, quiet room.

FAQ

Is the CIC exam hard?

It is a professional-level exam: questions test how you apply IPC knowledge in real situations, across all 8 domains, with no going back to earlier questions.

How many questions can I get wrong on the CIC?

CBIC reports a scaled pass score of 700, not a fixed number of correct answers, so aim to be solid in every domain.

Can I retake the CIC exam if I fail?

Yes. Failing candidates receive a score report from 300 to 699; check CBIC's current retake rules and fee before reapplying.

What is the fastest way to prepare?

Follow the domain weights: the three largest domains first, then sterilization, then practice under timed, forward-only conditions. The CIC Exam Prep Course is built this way.
