Our free CNA practice test includes questions covering all major domains of the CNA certification exam: physical care skills, psychosocial care, role of the nurse aide, safety, infection control, and legal/ethical issues.
Each question includes detailed answer explanations so you understand not just the correct answer, but WHY it's correct — the same critical thinking approach used on the actual exam. You can take this CNA practice test online free, with no sign-up, and repeat it as often as you like.
Use this CNA exam practice test to rehearse both halves of the certification: a written (knowledge) exam and a hands-on skills evaluation. Federal rule 42 CFR 483.154 requires every state to let you choose a written or an oral exam, to draw the skills test at random from a pool of nurse aide tasks, and to pass both parts; the exact numbers below depend on which vendor your state uses. The CNA knowledge practice test on this page mirrors the written portion.
Prometric and Headmaster states use their own state test plans, but they cover the same federally required course content (42 CFR 483.152), so the domains above are a reliable study map for every vendor.
The written exam you sit depends on which vendor your state contracts, so match your practice questions to that format. Three vendors cover almost every state:
Passing standards are set by each state: Headmaster handbooks publish 70-75% on the knowledge test (Ohio 70%, Maryland and Oregon 73%, California and Montana 75%), while NNAAP and Prometric score reports show only pass or fail and publish no percentage. The skills portion is pass/fail on every critical step with every vendor. Because the content domains are set nationally, a CNA knowledge practice test free of charge like the one above prepares you for any vendor; use the numbers here to set your timer (about 60-100 seconds per question depending on vendor) and to decide whether to schedule the oral exam.
