How to Prepare for the CNA (Nursing Assistant)

About the real test

The CNA written competency exam is administered state by state, most commonly through Credentia (NNAAP), Prometric, or D&S/Headmaster, but the underlying content domains, basic nursing skills, personal care skills, residents' rights, and infection control, are set nationally and tested everywhere.

Things that make the biggest difference

Basic Nursing Skills and Personal Care Skills carry the most weight combined

Vital signs, positioning and transfers, and activities of daily living make up the largest share of most state exams. These are also the skills tested again on the hands-on skills portion, so mastering them pays off twice.

Residents' Rights questions have a clear, correct pattern

The right answer almost always favors dignity, privacy, choice, and informed consent. When in doubt between two options, choose the one that respects the resident's autonomy.

Know your state's specific vendor and renewal requirements

Testing vendor, question count, and renewal periods vary by state, some renew every 2 years, others require registry renewal on a different cycle. Confirm your state's specific process before test day.
