The CMA (Certified Medical Assistant) credential is issued by the American Association of Medical Assistants (AAMA) — the gold-standard certification for graduates of CAAHEP- or ABHES-accredited medical assisting programs. Earning the CMA demonstrates that you have met the rigorous academic and clinical competency standards set by the profession's oldest and most recognized credentialing body.
Unlike other medical assistant certifications, the CMA is exclusively available to graduates of accredited programs, making it the most academically validated credential in the field. This guide covers everything you need to know about the AAMA CMA exam: eligibility rules, exam format, content areas, renewal requirements, and career benefits.
Two credentials dominate the medical assisting field, but they are not interchangeable. The CMA is awarded by the AAMA (American Association of Medical Assistants), while the CCMA is awarded by the NHA (National Healthcareer Association). Understanding the distinction matters — many employers, especially large health systems and physician offices affiliated with CAAHEP-accredited programs, specifically require or prefer the CMA.
The most critical difference is eligibility: the CMA requires graduation from a CAAHEP- or ABHES-accredited medical assisting program, whereas the CCMA certification from NHA can be obtained through broader pathways including on-the-job experience. This makes the CMA a more selective, academically grounded credential.
Both certifications require periodic renewal, but the CMA renewal cycle is 60 months (5 years) and demands 60 continuing education units (CEUs), 10 of which must come from AAMA-approved content. The CCMA requires 14 CEUs every 2 years. Employers in hospital outpatient settings, multi-specialty clinics, and academic medical centers often distinguish between the two on job postings.
To sit for the CMA (AAMA) exam, candidates must meet one of three eligibility pathways, all of which require graduation from an accredited program:
There is no work-experience-only pathway for the CMA — accredited program graduation is always required. This is a fundamental distinction from credentials like the EMT certification, which also requires formal training but in a different healthcare domain. Candidates apply directly through the AAMA at aama-ntl.org and must pay the applicable exam fee.
The CMA is the only medical assistant credential that requires graduation from a CAAHEP- or ABHES-accredited program. This accreditation requirement ensures that every CMA-credentialed professional has completed standardized clinical and administrative training, including hands-on externship hours.
Employers at hospitals, multi-physician practices, and academic medical centers often filter candidates by CMA (AAMA) specifically because of this accreditation link. The AAMA also maintains a public verification directory, so employers can instantly confirm credential status and expiration — a transparency feature that reinforces hiring confidence.
If you hold a CMA from AAMA, always display it as CMA (AAMA) on your resume and badge to clearly distinguish it from NHA's CCMA credential.
The CMA exam is organized into three major content domains, each weighted to reflect the breadth of a medical assistant's scope of practice:
This domain tests foundational knowledge shared across all healthcare roles. Topics include medical terminology, anatomy and physiology, psychology and human behavior, professionalism and ethics, communication (written and interpersonal), and medical law including HIPAA compliance. Strong performance in the General domain often reflects the quality of a candidate's academic program.
The Administrative domain covers the operational side of a medical practice. Candidates must demonstrate competency in appointment scheduling and practice management software, medical records management (both paper and EHR), coding fundamentals (CPT, ICD-10, HCPCS), billing and insurance processing, patient financial services, and office management including supply inventory and facility compliance.
The largest and most heavily weighted domain, Clinical content tests hands-on patient care skills. Sub-topics include vital signs and patient intake, infection control and sterilization, assisting with examinations and minor procedures, electrocardiography (ECG/EKG), phlebotomy and specimen collection, urinalysis and CLIA-waived testing, pharmacology and medication administration (routes, calculations, controlled substance handling), and emergency preparedness. Many candidates find the Clinical domain most challenging due to its breadth and the precision required in pharmacology questions.
Certified Medical Assistants with the CMA (AAMA) credential consistently command higher salaries than uncertified medical assistants. According to the U.S. Bureau of Labor Statistics and AAMA salary surveys, credentialed CMAs earn 10–15% more on average than their non-credentialed counterparts, with median annual wages ranging from $38,000 to $50,000 depending on specialty, geographic location, and years of experience.
The employment outlook for medical assistants is strong: the BLS projects 15% job growth through 2032, much faster than the average for all occupations, driven by an aging population and expanding outpatient care settings. CMAs with experience in specialty areas — cardiology, oncology, orthopedics — or with additional credentials (phlebotomy certification, EKG technician) are especially competitive.
Top employment settings for CMA (AAMA) credential holders include outpatient physician offices, multi-specialty group practices, urgent care centers, Federally Qualified Health Centers (FQHCs), and hospital-affiliated ambulatory care clinics. The AAMA credential is particularly recognized in practices affiliated with CAAHEP-accredited training programs, where faculty often mentor CMA candidates and employers understand the accreditation standard.
