How CNA certification works: training, the state exam, and the nurse aide registry

What CNA certification actually is

CNA certification is a listing on your state's nurse aide registry, added after you pass the state's competency evaluation. Federal OBRA '87 rules require nursing homes to use aides who have passed that evaluation, so the registry record, not the certificate from your class, is what an employer looks up.

People say license, registration and certification for the same thing. Here is how the words usually map:

The three steps to CNA certification

Every state uses the same three-step path, even where the credential's name and the required hours differ.

1. Finish a state-approved training program

   Classroom teaching plus supervised clinical practice with real residents. The federal minimum is 75 hours; many states require more. The program must be on your state's approved list, or the hours may not count.

2. Pass the competency evaluation

   A written test (oral in most states) and a hands-on skills test, run by your state's vendor. See how the CNA test works and what the skills test checks.

3. Get listed on the state registry

   Once both parts are passed, the state adds you to its nurse aide registry. Look yourself up before your first shift and make sure the name matches your ID.

Paperwork before day one

Expect paperwork before the first class: a government ID, and in many states a criminal background check, often with fingerprints, plus health screening such as a TB test. The state and the program set the list, so get it in writing at enrollment. Book any fingerprint appointment early; it is the item most likely to push back your start date.

Choosing a training program

Check one thing before price or schedule: is the program on your state's approved list right now? Approved programs run at community colleges, high-school career centers, private schools and, in some states, nursing homes that train their own aides. The American Red Cross offers nurse assistant training in some areas too.

Classroom hours are sometimes offered online. Clinical hours are not: you practice on real residents under a nurse's supervision. Sort out shift swaps, rides and childcare for clinical days before you sign up, because a missed clinical day usually has to be made up.

Ask before you enroll

• Is the program on the state's approved list today?
• How many classroom and clinical hours, on which days and times?
• What is the total cost: tuition, state exam fee, uniform, background check, books?
• Does the program register you for the state exam, or do you apply yourself?
• Where are clinical hours held, and how far is that from home or work?

How long CNA certification takes

How long certification takes depends on three clocks: your state's training hours, your class schedule, and the wait for an exam seat and the registry update. The federal minimum is 75 hours of training; many states require more, and your state's approved programs will give you the exact figure.

Evening and weekend classes stretch the calendar, not the hours. Count back from the date you want to start work and leave room for one retake, since attempt limits and retake waits are state rules you can't see in advance.

If you work while you train

Ask for the full clinical calendar on the first day and put every date in your phone before you request time off. If you work nights, check what time clinical days start: a night shift followed by an early clinical start leaves you doing your first supervised bed bath on no sleep, which helps nobody.

Challenging the CNA exam

Challenging the CNA exam means going straight to the state competency evaluation without completing a state-approved nurse aide program. Some states allow it for certain people, most often nursing students partway through their coursework and aides trained or certified in another state. Who qualifies, and what proof they need, is decided state by state.

You won't find a list of challenge states here, on purpose: each state agency writes its own rule, and the rules change. Ask your state's nurse aide registry or health department, and get the answer in writing before you skip a course.

What to ask your state

• Do I qualify to test without a state-approved program, and on what basis?
• Which documents prove it: transcripts, a school letter, another state's registry record?
• Do I take both parts of the exam?
• Is there a deadline after my coursework to apply?

Nursing students have a second trap on the written part: answering as a nurse. The test rewards the aide's scope, so an option that needs a nurse's judgment, like assessing a wound or adjusting oxygen, is the wrong answer for the aide. Run the practice test to recalibrate.

Same credential, different names

Several states give the nurse aide credential their own name. It is still a listing on that state's nurse aide registry, built on the same federal training and testing standard.

CNA

Certified Nursing Assistant, the most common name

STNA

State Tested Nurse Aide, Ohio's name; see the STNA test page

LNA

Licensed Nursing Assistant, used in New Hampshire, Vermont and Maine

NAC

Nursing Assistant Certified, Washington's name

Nurse Aide I

North Carolina's registry title for the entry-level listing

Registered nurse aide

The wording some states use for the same registry listing

GNA

Geriatric Nursing Assistant, a Maryland credential layered on top of the CNA, not a replacement for it

Moving to another state with your CNA

There is no national CNA license and no automatic reciprocity. When you move, the new state decides whether to accept your listing, usually through a transfer it calls endorsement or reciprocity, and it sets its own conditions.

1. Keep the old listing active

   Don't let it lapse before you move. A current listing in good standing is what the new state verifies.

2. Contact the new state's registry

   Ask for its out-of-state application and the list of what it checks.

3. Expect possible extra steps

   Some states accept the transfer as is; others ask for more training hours, a background check or their own exam.

4. Check the new listing

   Look yourself up on the new state's registry before your first shift there.

The title doesn't travel either. An Ohio STNA applying elsewhere goes through that state's out-of-state process like anyone else, and the new listing uses the new state's name for the credential.

What can cost you the listing

A substantiated finding of abuse, neglect or misappropriation of a resident's property goes on your registry record and bars nursing-home work. The written test checks that you can name these: Client Rights is 8% and Legal and Ethical Behavior 5% of the 2024 NNAAP outline, and both cover the types of abuse.

Renewal rules exist too, and they are set by your state; your registry explains what keeps a listing active.
