CNA Practice Test FAQs
How many questions are on the CNA exam?
The NNAAP written exam has 70 multiple-choice questions — 60 scored questions and 10 unscored pretest questions. You get 2 hours to complete it. There is also a separate clinical skills test where you demonstrate 5 randomly selected nursing skills.
What score do I need to pass the CNA exam?
Passing scores vary by state, but most states require roughly 70–80% on the written exam plus passing all 5 clinical skills. Check with your state's nurse aide registry for the exact cut score.
How should I study for the CNA test?
Focus on the three biggest topic areas: physical care skills, psychosocial care, and the role of the nurse aide. Take timed practice tests like this one to build speed, and always read the explanations — understanding why an answer is right matters more than memorizing it.
Is the CNA exam hard?
The CNA exam is very passable with preparation. Most candidates who complete an approved training program and take several full practice tests pass on the first attempt. The clinical skills portion trips up more people than the written test, so practice those hands-on.
How long is CNA certification valid?
CNA certification is typically valid for 2 years, though some states use different renewal cycles. Renewal usually requires proof of recent employment as a nurse aide and sometimes continuing education hours.
