What is CNA certification?
CNA (Certified Nursing Assistant) is a state credential for nursing assistants who give direct patient care under a nurse's supervision. Your state issues it, and your entry on that state's nurse aide registry is what proves it. Federal law sets the floor at 75 clock hours of training, at least 16 of them supervised practical training, followed by a competency evaluation with a knowledge test and a hands-on skills test. States are free to demand more. California requires 160.
CNA vs HHA vs PCA vs medication aide
Four job titles cover adjacent work in long-term care, with different training behind them and different things you're allowed to do.
| CNA | Direct nursing care in any setting, under a nurse. Skilled nursing facilities run on it, because the federal training rules were written for them. |
|---|---|
| HHA | Personal care and basic health support in the patient's home, for a Medicare-certified agency. Shorter training, narrower setting. |
| PCA or caregiver | Non-medical help: bathing, dressing, meals, company. Often no state credential at all, and pay reflects that. |
| Medication aide | A CNA who did extra training and can give medications in long-term care under a nurse. |
The CNA card reaches further than most people expect. Federal law lets a CNA who is currently listed in good standing on the state registry qualify as a home health aide for a Medicare-certified agency, without separate HHA training. Individual states can add requirements on top.
Who requires CNA
Skilled nursing facilities and nursing homes ask for it most, because the federal rules are written for them. Hospitals ask for it under other titles, including patient care technician. Home health aide and hospice aide roles ask for it too, sometimes accepting it in place of a home health aide certificate. Personal care aide and caregiver roles without hands-on clinical tasks generally don't ask, and they pay less for the difference.
Requirements and eligibility
- Finish a state-approved training program. The federal floor is 75 clock hours; your state sets the number that applies to you.
- Get at least 16 hours of supervised practical training inside that program.
- Cover the 16 hours of basics that federal law requires before any direct contact with a resident: communication, infection control, safety, promoting independence, and residents' rights.
- Pass the competency evaluation. It's two parts, a written or oral test and a skills demonstration, and federal law says you have to pass both and gives you at least 3 attempts.
- Pass a background check.
- Get listed on your state's nurse aide registry. Until that entry exists, the certification doesn't do anything for you.
- No degree, and no prerequisite credential.
Cost, training hours, and renewal
If you're employed by a facility, or holding an offer from one, on the day your training starts, federal law forbids charging you for any part of the program. If you paid your own way and then get hired, or get an offer, within 12 months of finishing, your state has to reimburse what you paid, pro rata over the time you work as a nurse aide. Ask about both before you hand over a card.
| Training cost | $0 if a facility employs you or has offered you a job when training begins. Pro rata reimbursement if you're hired or offered a job within 12 months of finishing |
|---|---|
| Training hours | 75 minimum under federal law. California requires 160: 60 hours of classroom theory and 100 of supervised clinical |
| Exam fee | Set by your state and its testing vendor |
| Format | A written or oral knowledge test plus a hands-on skills demonstration. You pass both or you retake |
| Validity period | Set by your state. 2 years is a common cycle |
| Renewal requirement | Nursing work in the period, on your state's schedule. Some states require the work to be paid, and some add in-service hours |
| If you stop working | 24 consecutive months performing no nursing or nursing-related services, and federal rules remove you from the registry |
| Getting back on | A new training and competency evaluation program. There's no fee that fixes it |
| Issuing body | Your state, over a federal floor set by 42 CFR 483 |
Your registry listing is the credential
The registry is what employers check and what the law cares about. Before a facility lets you work as a nurse aide it has to get registry verification that you passed a competency evaluation, unless you're a full-time employee in a state-approved program or can prove you've just completed one. It also can't keep you on as a nurse aide for more than 4 months full time unless you've completed a training and competency evaluation program, which is why facilities will pay to train you and then push you toward the exam.
Three things about the registry catch people. It drops you after 24 consecutive months performing no nursing services, and no renewal fee or refresher reverses that: you retrain and retest. Findings of abuse, neglect, or misappropriation of property stay on your entry permanently, while ordinary entries get removed for inactivity. And registries are per state, so moving means applying to the new state's registry for reciprocity.
How to get certified
- Look up your state's required hours before you shop for a program. The federal 75 is a floor, and California's 160 shows how far above it a state can sit.
- Ask facilities near you whether they train. If one employs you or offers you a job before training starts, the program can't charge you.
- Finish the program, including the supervised practical hours.
- Pass both halves of the competency evaluation, the knowledge test and the skills demonstration.
- Clear the background check and get your entry on the state registry.
- Keep nursing work on the books. That's what renewal measures.
Demand for CNA on MedJobList
CNA is named in 151 of the active US openings we track right now, at any level from required to preferred. The filter behind that number reads the whole posting, so "CNA required" and "CNA preferred, we'll train you" both land in it. Read the requirement line before you rule a job out. You can browse those openings below, or filter the full job list by CNA yourself.
On the job
Keep your own record of the shifts you work. Renewal turns on proof of nursing work, and producing it is your burden, which stings if the agency you worked for has since closed. If you're moving states, start the reciprocity application before you quit.
FAQ
Federal law sets a floor of 75 clock hours, including 16 hours of supervised practical training, and your state sets the requirement above it. California requires 160 hours, split into 60 hours of classroom theory and 100 hours of supervised clinical work. Programs at the federal floor can run in a few weeks; California's takes longer.
It can be $0. Federal law forbids charging a nurse aide who is employed by a facility, or who holds an offer from one, on the day the training program starts. If you pay your own way and then get hired or receive an offer within 12 months of finishing, your state has to reimburse what you paid, pro rata over the time you work as a nurse aide. Exam fees are set by each state and its testing vendor.
Your registry entry lapses. Go 24 consecutive months performing no nursing or nursing-related services and federal rules remove your entry, at which point you complete a new training and competency evaluation program to get back on. Your state may also run its own renewal cycle, often 2 years, and some states require proof that the work was paid.
Not automatically. Registries are maintained state by state, so you apply to the new state's registry for reciprocity or endorsement, and it decides whether your training and testing meet its rules. Start the application before you move.
No. CNA training is broader and works in any setting under a nurse's supervision. HHA training is shorter and aimed at personal care and basic health support in a patient's home for a Medicare-certified agency. Federal law does let a CNA in good standing on the state registry qualify as a home health aide for a Medicare-certified agency without separate HHA training, and states can add requirements on top.
