Is the CNA exam hard? How many questions it has, how the skills test works, what it costs in real states, why people fail, and how to pass on your first try.

Is the CNA exam hard? For most people who complete a state-approved nurse aide training program, it’s very passable. You aren’t being asked anything you didn’t practice in class. But the exam has two very different parts, a knowledge test and a hands-on skills evaluation, and each has its own traps. Here’s how many questions to expect, how the skills test works, what it costs in real states, and how to walk in confident.
Is the CNA exam hard? The short answer
The material itself is not advanced. It’s the basics of safe, respectful care: infection control, safety, personal care, communication, client rights and your role on the care team. What makes the exam feel hard is the format. The written test uses scenario questions where two answers look reasonable, and the skills test is graded step by step while someone watches you. With practice in both formats, most candidates pass.
What are the two parts of the CNA exam?
Federal rules require nurse aides who work in Medicare- or Medicaid-certified nursing facilities to pass a state-approved competency evaluation. Every state builds it from the same two pieces:
States contract different testing companies, including Credentia (which delivers the NNAAP exam in many states), Prometric, Headmaster/D&S Diversified Technologies and others. That’s why your friend in another state may describe a slightly different test. For a step-by-step look at Part 2, read our CNA skills exam guide.
How many questions are on the CNA exam?
In states that use the National Nurse Aide Assessment Program (NNAAP), Credentia states that the written exam has 70 multiple-choice questions and you have 2 hours to complete it. The oral version, where questions are read aloud, has 60 multiple-choice questions plus 10 reading-comprehension questions, and you must pass both sections.
The NNAAP written exam is built around three broad areas:
- Physical care skills: activities of daily living, basic nursing skills and restorative care.
- Psychosocial care skills: emotional, mental health, spiritual and cultural needs.
- Role of the nurse aide: communication, client rights, legal and ethical behavior, and teamwork.
Other testing programs use different counts, so look up the exact number in your state’s handbook.
Where do candidates struggle on the CNA exam?
On the written test
- “Best first action” questions. Several answers are good care; the exam wants the safest or most appropriate one first, often reporting to the nurse.
- Scope of practice. Knowing what a nurse aide may and may not do, such as giving medications or changing care plans.
- Client rights and privacy. Dignity, choices, privacy and confidentiality questions are easy to overthink.
On the skills test
- Skipped critical steps. Forgetting hand hygiene, privacy or leaving the call light within reach can fail a skill.
- Measurement accuracy. Your reading must fall within a set range of the evaluator’s. Credentia’s NNAAP skills list uses ±4 beats for a radial pulse and ±2 breaths for respirations.
- Nerves. People rush and skip steps they know well. Practicing out loud fixes this.

How do you make the CNA exam easier?
- Get your state’s handbook. It has the exact format, the skills list, and rules for ID, scrubs and arrival time.
- Practice written questions daily. Twenty to thirty questions a day with explanations builds the judgment the scenarios test.
- Rehearse every skill on the list, out loud, until the critical steps are automatic, especially hand hygiene and measurements.
- Simulate test conditions. Have someone read the steps while you perform a skill under a time limit.
- Sleep, eat and arrive early. Nerves cause more skills-test failures than lack of knowledge.
If your exam is delivered at a testing center, our exam day guide explains check-in and ID rules that apply to most computer-based tests.
What happens after you pass the CNA exam?
Once you pass both parts, the testing company reports your results to the state and you’re added to your state’s nurse aide registry, which employers use to verify your status. If you fail one part, you usually retake only that part. Most states limit how many attempts you get within a set period after training, so book your retest promptly.
