What Is the CNA Exam Like? The Written and Skills Portions Explained

In most states, the CNA exam is the NNAAP — the National Nurse Aide Assessment Program — and it has two parts: a knowledge test and an in-person skills evaluation in which you perform care tasks in front of a trained evaluator. The exam standards come from the National Council of State Boards of Nursing, and the official administrator handling registration, scheduling, and state-specific candidate handbooks is Credentia. You must pass both parts to be placed on your state's nurse aide registry.

Part one: the knowledge test

The knowledge portion covers the material from your training program — the same curriculum federal regulation requires every approved program to teach (see what CNA training covers). The format details, including whether an oral version is offered where you live and what identification you must bring, are spelled out in your state's candidate handbook, which you can find through Credentia. Read that handbook early, not the week before your test date — it is the single document that answers most exam-day questions authoritatively for your state.

Part two: the skills evaluation

The skills evaluation is the part that surprises people. You are assigned a set of care skills and must physically perform them, in order and correctly, while an evaluator watches. These are the same tasks you practiced during your program's supervised practical hours — the hands-on training that 42 CFR § 483.152 requires every approved program to include.

Two things matter more in the skills evaluation than test-takers expect:

• Technique details count. Infection-control technique runs through the entire evaluation, not just one station. As one example of the level of precision involved, the government reference on wearing gloves in the hospital from MedlinePlus walks through when gloves are worn and the specific removal sequence that keeps contaminated surfaces away from your skin. Skills evaluations care about exactly that kind of detail — sequence and technique, not just outcome.
• The person in front of you matters. Skills are performed on a person (often a volunteer or fellow candidate acting as the resident), and evaluators watch how you communicate, protect privacy, and ensure safety throughout — the habits your supervised practical hours were designed to build.

Where the rules for your state live

Because certification is administered state by state, the specifics — how many skills you perform, passing standards, fees, retake rules, what happens if you fail one part — belong to your state's candidate handbook, not to any general article, this one included. The handbooks are published through Credentia, and the NCSBN page on the NNAAP is the standards-body reference for what the exam program is. When a claim about the exam on any website conflicts with your state's handbook, the handbook wins.

How to prepare sensibly

Your training program is the preparation — the exam tests what an approved curriculum must teach. Beyond that, the free, openly licensed Nursing Assistant textbook from Open RN, published on the National Library of Medicine's Bookshelf, covers the same ground as the curriculum and is a solid review resource that costs nothing. Pair it with your state handbook's skills list, and practice the skills physically, out loud, in sequence — the evaluation rewards rehearsed technique, not recalled facts.
