Medical Assistant Certification Guides

Everything on the CMA, RMA, and CCMA credentials in one place: what certification is, how the credentials differ, how to get certified, and how to keep one current. Certification is a voluntary credential, not a license, and it does not expand your scope of practice.

Compare credentials

The three major national credentials, each from a different certifying body. None is universally best; the right one is what you qualify for and what your local employers ask for.

Credential	Body	Common route	Renewal
CMA (AAMA)	Certified Medical Assistant	Graduates of a CAAHEP- or ABHES-accredited program	Every 60 months
RMA (AMT)	Registered Medical Assistant	Education, work-experience, military, or instructor routes	Three-year CCP cycle
CCMA (NHA)	Certified Clinical Medical Assistant	Diploma or GED plus recent training or experience	Every two years

Eligibility and renewal rules are set by each body and change. Confirm current requirements in the body's official handbook, and see the CMA vs. RMA comparison for the two most common credentials side by side.

Keep certification current

Continuing education and renewalEvery credential expires without maintenance, and each body sets its own cycle. How renewal works, what counts, and why a lapse is harder to fix than to prevent.

Scope and legal limits

Certification does not expand what a medical assistant may legally do. Your duties depend on state law, employer policy, training, and supervision.
