Certified Medical Assistant: Which Credential Should You Get?

A certified medical assistant is a medical assistant who has passed a recognized national exam and holds the credential to prove it. That's the short answer. The part that trips people up is that there isn't one exam called "the medical assistant certification." Several separate organizations each run their own, each with its own initials after your name, and employers don't all treat them the same way. So before you sign up for a program or pay a fee, the real question isn't whether to get certified. It's which one, and that choice depends on the path you took to get here.

Here's how the main credentials actually differ, and how to pick without wasting a year on the wrong one.

What "certified" actually adds

You can be hired as a medical assistant without any credential in some settings, especially small practices willing to train. But hiring has drifted steadily toward credentialed candidates, and a national certification is increasingly the thing that moves a résumé past the first filter, particularly at hospitals and larger systems that screen automatically.

What the letters signal is that you didn't just learn the tasks on the job in a piecemeal way. You sat a standardized exam that covers both halves of the role, the clinical procedures and the administrative records side, and you cleared a national bar. If you're fuzzy on what that two-sided job even involves day to day, what a medical assistant actually does all day lays it out before you commit to a credential built around it.

The medical assistant certifications, side by side

Four sets of initials cover the vast majority of certified medical assistants. Here are the three you'll see most, plus a note on the rest.

Credential	Issuing organization	Main eligibility route	Renewal
CMA (AAMA)	American Association of Medical Assistants	Graduate (or student) of a medical assisting program accredited by CAAHEP or ABHES	Every 5 years, 60 CEUs (or re-exam)
CCMA	National Healthcareer Association (NHA)	High school diploma/GED plus a completed MA training program or qualifying work experience	Every 2 years, 10 CE credits
RMA	American Medical Technologists (AMT)	Several routes; confirm current criteria with AMT	Ongoing continuing education

A fourth option comes from the National Center for Competency Testing (NCCT), which also certifies medical assistants. It shows up in job postings less often than the three above, so treat it as a secondary choice and check whether local employers actually recognize it before you commit.

Two things jump out of that table. First, the CMA (AAMA) is the strictest on the front end: its primary route requires you to have gone through a formally accredited program. Second, the CCMA is the most flexible, because the NHA gives you a work-experience pathway if you didn't come up through a traditional program. That single difference decides the choice for a lot of people.

CMA vs CCMA: which one do employers want?

This is the comparison that matters most, because the CMA (AAMA) and the CCMA (NHA) are the two you'll see named in postings far more than any other.

The honest answer is that it's regional and employer-specific. Some hospital systems and physician networks list the CMA (AAMA) by name because it's the older, program-gated credential and they treat that gate as a quality signal. Others accept "CMA or CCMA or RMA" interchangeably, and a growing number of employers specifically name the CCMA because the NHA credential is widely used by the training programs feeding them candidates.

The practical way to decide: look at the actual job listings in your area for the kind of practice you want to work in, and see which letters they ask for. Ten minutes on a job board tells you more than any general ranking. If your local hospitals keep writing "CMA (AAMA) required," that settles it. If they write "national MA certification" or list several, you have room to pick the one that fits your background.

And that's the real deciding factor, your background:

• You completed, or are about to complete, an accredited medical assisting program → the CMA (AAMA) is on the table for you, and if local employers prize it, take it.
• You've been working as a medical assistant without a formal accredited program, or you trained through a route that doesn't meet the AAMA's accreditation rule → the CCMA's experience pathway may be your realistic option, and it's a respected credential in its own right.

Do you even need to be certified?

Sometimes no, but the trend is against banking on that. A handful of small offices will still hire and train uncertified assistants, and a few states have their own rules that shape what you can do. But across the field, certification has moved from "nice to have" to "expected," and the settings that pay better and offer more stability are the ones most likely to require it.

So even if you land a first job without a credential, treat certification as the next step rather than something you can skip indefinitely. The uncertified path tends to cap out faster.

How do you actually become certified?

The route looks similar across credentials, with the eligibility rules being where they diverge.

1. Confirm you're eligible for the specific exam you want. This is the step people skip, and it's the expensive one to get wrong. The CMA (AAMA) generally requires graduation from a CAAHEP- or ABHES-accredited program (with a few narrow alternative categories). The CCMA lets you qualify through a training program or documented work experience. Check the current requirements on the issuing organization's own site, aama-ntl.org for the CMA and nhanow.com for the CCMA. Those are the only sources that are actually authoritative.
2. Apply and pay the exam fee, submitting whatever transcripts or attestations your eligibility category requires.
3. Study across the whole scope, not your favorite third of it. These exams reward broad, steady competence: clinical procedures, patient care, safety, and the administrative and basic billing knowledge a practice runs on. The people who pass comfortably practiced across the entire range instead of cramming the part they already liked.
4. Sit the exam, then keep the credential alive through the renewal cycle in the table above.

For the CCMA specifically, that renewal cycle is every two years with 10 continuing education credits, which is a lighter recertification load than the CMA's five-year, 60-CEU cycle. Neither is onerous if you stay on top of it; both become a scramble if you let the credential lapse.

Does certification change your pay and hiring odds?

The durable pattern across healthcare support roles is that certified staff tend to out-earn and out-compete uncertified staff doing the same work. It's not a magic raise, and exact figures swing a lot depending on where you work and how much experience you bring, so be skeptical of any blog that quotes you a single national salary number as if it's a promise. What certification reliably changes is access: more postings will consider you, and the employers that filter by credential stop screening you out automatically.

It's the same dynamic on the neighboring administrative side of healthcare, where certified medical coders consistently earn more than uncredentialed ones for the same reason. A credential is a signal that lowers an employer's risk in hiring you, and that signal has a price they're willing to pay.

Quick answers

How long is a medical assistant certification good for? It depends on the credential. The CCMA renews every two years (10 CE credits); the CMA (AAMA) renews every five years (60 CEUs, or by re-examination). Let either lapse too long and you may have to recertify by exam.

Can you get certified without a formal program? For the CCMA, yes. The NHA offers a work-experience pathway. For the CMA (AAMA), the main route requires an accredited program, though a few alternative categories exist. Always confirm on the issuing organization's site.

Which certification is "the best"? There's no universal winner. The best one is the credential your local employers actually ask for and that you're eligible to sit given your background. Check real job postings before you choose.

Bottom line

Becoming a certified medical assistant means passing a national exam and holding the credential. But "the" certification is really three or four different ones (the CMA, CCMA, and RMA, plus a less common option from the NCCT), each run by a different organization with its own eligibility rules and renewal cycle. The CMA (AAMA) is the program-gated, five-year credential; the CCMA is the more flexible one with a work-experience pathway; the RMA is a third widely accepted option. Pick by matching two things: what your local employers list in their postings, and which exam you actually qualify for.

If you're still weighing whether this is even the corner of healthcare you want, it's worth reading what a medical assistant does all day and, for the quieter records-and-coding path next door, what a medical coder does all day. The credential is a means to a job you'll actually spend your days in, so start there, then certify for it.
