CCMA vs CMA vs RMA vs NCMA

CCMA vs CMA comes down to who awards it: the CCMA® is the National Healthcareer Association's (NHA®) exam, the CMA (AAMA) belongs to the American Association of Medical Assistants. The RMA is American Medical Technologists' and the NCMA is the National Center for Competency Testing's. Four bodies, four exams, four eligibility rulebooks, four scoring scales that cannot be converted into each other.

Most pages answering this question are written by schools selling one route, and they quote each other. Every number below comes from the awarding body's own website or PDF, read on October 13, 2026. Where a body does not publish something, we say so.

The four exams at a glance

The passing scores do not translate

Look at the scale row again. 390 on NHA's 200–500 scale, 405 on AAMA's 200–800, 70 at AMT, 575 on NCCT's 200–720. Each body scales its own exam to its own standard, and none publishes a formula linking its scale to anyone else's. So "the CMA is harder because 405 is a higher number" means nothing, and neither does "the CCMA passing score is 78%" — a myth we take apart in why 390 is not a percentage. Compare the exams by what they test and who they admit. Not by the numbers on the score report.

Eligibility: where the four really split

This is the difference that decides which exam you can sit, so read the row for your situation.

CCMA (NHA). A high school diploma or GED, plus either a medical assistant training program completed within the last five years, or supervised medical assisting work experience — one year within the last three, or two within the last five (two within five is the only work route for California residents). Students still in school can test up to 18 months before graduating, for a provisional credential that has to be converted. Whether NHA requires the training program to be CAAHEP- or ABHES-accredited, its eligibility page does not settle; ask NHA if that is your deciding factor. CCMA eligibility questions covers the details.

CMA (AAMA). Built around accredited programs. Categories 1 and 2 are for completing students and graduates of a CAAHEP- or ABHES-accredited medical assisting program; completing students can test no more than 30 days before finishing. There is a fourth route, the Alternative Pathway: a postsecondary program of at least 560 academic contact hours plus a 160-hour practicum (or 1,000 hours of medical assisting experience), at an institution accredited by a body the U.S. Department of Education or CHEA recognizes, with your documents reviewed and approved before you apply. What AAMA does not offer is a work-experience-only route.

RMA (AMT). Five routes: education (a program completed within the past four years), competency and work-based learning, work experience (three of the past seven years as a medical assistant), military training, and instructor. The education route asks for 720 hours of instruction including a 160-hour externship, at a program or institution accredited by an agency approved by the U.S. Department of Education or CHEA, or otherwise approved by AMT — not only CAAHEP or ABHES.

NCMA (NCCT). Six routes, including current high school students, current students and graduates of an NCCT-authorized program (within five years), one year of full-time medical assisting experience within the past five years, military, and instructor.

The pattern: if you trained on the job rather than in a program, the CMA (AAMA) is the one exam of the four with no route for you.

What is actually tested

Every exam covers clinical, administrative and general knowledge, but the weighting differs, and weighting is what you study to. The CCMA puts 84 of its 150 scored questions — 56% — in Clinical Patient Care, with phlebotomy at 12 and EKG at 6; the full CCMA exam breakdown lists all seven domains and the 3A–3F split. AMT's RMA outline puts 115 of 210 items in clinical medical assisting. NCCT's NCMA plan puts 72 of 125 scored items in clinical procedures, including 15 phlebotomy and 10 ECG. Study material written for one exam is weighted for that exam. A CMA review book is not a CCMA blueprint, however similar the topics look.

Which one should you take?

The one your program, your employer or your state route points you to — and that is a question about you, not about which credential is "best." We will not rank them on pay or on how many employers ask for each, because none of the four bodies publishes a number we could check. What we can say from the rules above:

• Trained in a CAAHEP- or ABHES-accredited program? That is the CMA (AAMA)'s main route. For the RMA and the NCMA, check your program against AMT's accreditation rule and NCCT's authorized-program requirement; for the CCMA, the program must be within the last five years.
• Trained on the job? CCMA, RMA and NCMA have experience routes. The CMA (AAMA) does not.
• Still in high school? CCMA (provisional) and NCMA both have a route for you.
• Job posting names a credential? Sit that one. Confirm the awarding body, not just the letters.

If it is the CCMA, the exam is 180 questions in 3 hours, drawn to NHA's published counts — and our free full-length CCMA practice test runs at exactly that structure. Free account, no card.

FAQ

Is a CCMA the same as a CMA?

No. The CCMA is awarded by the National Healthcareer Association; the CMA (AAMA) by the American Association of Medical Assistants. They are separate exams with different eligibility rules, different lengths (180 questions in 3 hours versus 200 in 160 minutes) and different passing standards (390 on a 200–500 scale versus 405 on 200–800).

Is the CMA harder than the CCMA?

Neither body publishes anything that would let you compare difficulty, and the passing scores sit on different scales, so a higher number does not mean a harder exam. The clearer difference is access: the CMA (AAMA) requires an accredited or pre-approved program, while the CCMA also admits candidates through work experience.

What is the difference between the CCMA and the RMA?

The CCMA is NHA's: 180 questions, 3 hours, pass at 390 on 200–500, renewed every two years with 10 CE credits. The RMA is American Medical Technologists': 210 items on its content outline, 2 hours, pass at a scaled 70, kept active with an annual fee and 30 points per three-year cycle.

Can I take the CMA (AAMA) without going to school?

Not on work experience alone. AAMA's routes are for students and graduates of CAAHEP- or ABHES-accredited programs, plus an Alternative Pathway that still requires a qualifying postsecondary program or apprenticeship. The CCMA, RMA and NCMA all publish experience-based routes.

Do I need a CAAHEP- or ABHES-accredited program?

For the CMA (AAMA)'s main categories, yes; its Alternative Pathway accepts other accredited institutions after a document review. AMT accepts programs accredited by agencies the U.S. Department of Education or CHEA approves, or that AMT approves itself, and NCCT requires an NCCT-authorized program. For the CCMA, NHA's eligibility page does not say either way — ask NHA before you pay if it matters to you.
