Home health aide vs certified nursing assistant, and which one to hire

Here’s the fact most hiring guides for home care skip. A home health aide and a certified nursing assistant train under the same federal floor: 75 hours, set by the Nursing Home Reform Act of 1987. Same law, same number, for both roles, wherever an agency runs on Medicare certification.

So the framing you’ve probably seen, that a CNA is simply “more trained” and an HHA is the lighter-weight hire, isn’t the federal story. It’s a state-by-state one. Most of what decides whether you need an HHA or a CNA for your next open case has nothing to do with who studied longer. It comes down to who’s paying for the care and what that specific client actually needs done in their home.

The training-hours story is real, just not where you’d expect it

Thirty states plus DC now require more than 75 hours to certify a nurse aide, some going as high as 180 in Maine, according to PHI’s state-by-state tracking. Only 17 states plus DC have done the same for HHA training, topping out lower, around 140 in Alaska. Thirty-three states leave HHA training sitting exactly at the federal floor, so in most states a CNA candidate probably did sit through more clock hours. Check your own state’s actual numbers before you build a posting around that assumption, because in roughly a third of states, the gap you’re picturing doesn’t exist.

Where states do add CNA hours, they’re mostly adding facility-context training: transfers with lifts, charting in a clinical record, working on a team with an RN on shift. That’s built for a nursing home or hospital floor, not for the tasks that fill most home care shifts: bathing, dressing, meal prep, medication reminders, transportation, and company.

The fork that actually matters is your payer model, not the resume

A non-medical home care agency and a Medicare-certified home health agency are two different licenses, with two different scopes of practice and two different sets of payer rules, even when the same company holds both. That split matters more to this hiring decision than anything on a training transcript.

If your agency is private-pay or Medicaid-waiver, non-medical, personal care only, an HHA is built for exactly that work. Nothing about a CNA credential unlocks extra legal authority here, because there’s no RN writing a plan of care for the aide to work under in the first place.

If you’re Medicare-certified and delivering skilled care ordered by a physician, with an RN supervising the plan, that structure is what lets an aide take on more: vitals reported up the chain, certain delegated tasks, closer clinical documentation. That’s the setting a CNA’s training and registry listing were built for.

The one question to ask before you post the role

Is there an RN attached to this case who will delegate and supervise clinical tasks, or is this a personal-care case with no nurse in the loop? The answer tells you which role to hire far more reliably than “which certification sounds more advanced.”

What a CNA can do that an HHA can’t, and where that line moves

This is the honest steelman for hiring a CNA even outside a skilled agency: in states that allow nurse delegation, an RN can transfer authority for a specific task, like assisting with insulin, to an aide who’s completed the right training and competency check. New York’s Advanced Home Health Aide role is a real example of that. It authorizes routine and prefilled medication administration, but carves out insulin injections, other diabetes injections, and a short list of other high-risk tasks by name.

California runs the opposite direction. Its rules don’t permit an RN to delegate insulin administration to a home care aide at all, CNA or HHA. Same task, same country, different answer, because scope of practice here is set state by state, not by the credential’s initials.

So “can a CNA do more” is the wrong question. The right one is what your state’s board allows to be delegated, to whom, and under what supervision, for the task this client needs. A CNA title without that delegation structure behind it doesn’t grant the extra scope. It just costs more.

The part that trips up agencies who hire a CNA anyway

Here’s the detail most owners never hear until it costs them a hire. To keep a CNA certification active, most states require the aide to log paid hours performing nursing-related duties under a licensed nurse’s supervision within a rolling 24-month window. Miss that window and the certification lapses. The aide has to retest, the same registry check we walk through in our guide to CNA interview questions.

If you bring a CNA onto a roster that never puts them under nursing supervision, because your agency is private-pay and non-medical, you’re not just paying a premium for scope you can’t use. You’re watching the credential you paid extra for quietly expire on your own payroll.

What this looks like when you’re staffing an actual case

Say a family calls about a parent who needs help getting up, bathing, and remembering an evening pill, with no nurse attached to the case and no physician’s plan of care behind it. That’s an HHA case. Hiring a CNA here buys nothing but a bigger number on the offer letter.

Now say a client is coming home after a hospital stay on a home health benefit, with a nurse checking in weekly and vitals that need to be tracked between visits. That’s a CNA case, ideally one your intake already flags as needing an active registry listing and a scope of practice check, because the delegation and reporting structure only works with that role in place.

Most small agencies staff both kinds of cases from the same roster, sometimes the same month. A quick qualification question on every posting, “which certification do you hold, and is your registry status currently active,” sorts that fork before you’re deep into an interview with the wrong role for the case in front of you.

Verifying the claim is a different job than screening for the person

None of this changes the fact that a certification checkbox on an application is a self-reported claim, not a verified one. Whether someone says HHA or CNA, you still don’t know from a resume alone whether they’ll show up reliably, talk a worried family member off the ledge, or stay steady when a client has a hard day. Those are the questions that decide whether a hire sticks, on either credential.

Truffle is a candidate screening platform that combines resume screening, one-way video interviews, and talent assessments, and for a role like this, each one does a different job. A qualification question at intake (“currently certified as HHA or CNA in this state, registry status active”) flags what a candidate claims, so you’re not reading a resume line by line to find it. A short one-way interview question, something like “walk me through the last time you had to reposition or assist a client who couldn’t move much on their own,” gets you a real answer instead of a rehearsed one, and AI Match scores it against what you told the system mattered at intake. Candidate Shorts pull the moment worth watching instead of making you sit through the full recording.

None of that replaces the registry lookup or the delegation and scope-of-practice check, and it shouldn’t claim to. Truffle doesn’t verify a license against a state database. What it does is make sure the background check and registry verification you still run yourself land on someone you already have real reason to trust, instead of being the first thing you learn about them.

The credential picks the paperwork. The case still picks the person

Deciding between an HHA and a CNA posting is mostly a compliance question: what does this client’s care plan require, who’s supervising it, and what does your state allow to be delegated to whom. Get that fork right and you’ve picked the correct box to check on the job posting.

It doesn’t tell you anything about whether the specific person in front of you is reliable, steady under pressure, or good with a scared family member on the phone. That part of the decision was never about the initials after someone’s name. It’s the same screening work, on either title, and it’s worth building the same way every time a case comes in.

If you’re staffing both kinds of roles on the same roster, resume screening and talent assessments are worth setting up alongside a short one-way interview, especially for a team hiring without a dedicated recruiter to sort it out case by case. See the full plans, or read how the same layered approach plays out when screening candidates for a home care agency broadly.

Frequently asked questions about hiring an HHA vs a CNA

Is a CNA always a “step up” from a home health aide?

Not by training hours alone. Both roles share the same 75-hour federal floor. Whether a CNA in your state trained longer depends on whether that state chose to raise its own minimum, and about a third haven’t. The bigger difference is what setting and supervision structure each role was built to work inside, not which one sat in class longer.

Can I hire a CNA for a private-pay, non-medical case?

Yes, and plenty of agencies do. Just know it usually doesn’t buy you extra legal scope on that case, because there’s no RN attached to a non-medical, private-pay case to delegate clinical tasks in the first place. You’re hiring a CNA to do HHA-scope work, at CNA-level pay.

Does a CNA’s certification expire if they only do personal care work?

It can. Most states require a CNA to log paid hours under a licensed nurse’s supervision within a rolling 24-month period to stay active on the registry. An aide working only non-medical, private-pay cases with no nurse involved may not meet that requirement and could have to retest.

Who checks whether a candidate’s HHA or CNA certification is real?

You do, separately from any screening step. Truffle can flag what a candidate claims at intake, but verifying it against your state’s nurse aide registry or HHA credentialing body is a manual check you or your compliance team run before the person works unsupervised with a client.

Does the answer change if my state allows nurse delegation for tasks like insulin?

It can, but only for the specific tasks your state names and only with an RN actively delegating and supervising. New York’s Advanced Home Health Aide role is one example of that expanded scope. California doesn’t permit the same delegation for insulin at all. Check your own state board before assuming a broader scope travels across state lines.
