In the medical field, RMA stands for Registered Medical Assistant. It’s a professional certification issued by American Medical Technologists (AMT), a not-for-profit association of allied health professionals. The credential has been offered since 1972 and signals that a medical assistant has met specific education and competency standards to work in clinical and administrative healthcare settings.
What an RMA Actually Does
A Registered Medical Assistant works alongside physicians and nurses in outpatient clinics, physician offices, hospitals, and specialty practices. The role spans both clinical and administrative tasks, which makes it unusually versatile compared to other entry-level healthcare positions.
On the clinical side, RMAs take vital signs, prepare patients for exams, collect lab specimens, assist with minor procedures, and administer medications under a physician’s supervision. On the administrative side, they handle scheduling, insurance paperwork, medical records, billing codes, and patient communication. Many RMAs shift between both roles throughout a single workday depending on the size of the practice.
Scope of practice laws for medical assistants vary by state. In some states, medical assistants aren’t even mentioned by name in the law and are classified as unlicensed personnel. This means the specific tasks you’re allowed to perform, particularly around injections, phlebotomy, and medication administration, depend heavily on where you work and what your supervising physician delegates to you.
How RMA Certification Works
To earn the RMA credential, candidates must meet AMT’s eligibility requirements, which typically involve completing an accredited medical assisting program or demonstrating equivalent work experience. The certification exam itself is 210 questions covering four major areas:
- Clinical patient interaction: 71 questions (33.8% of the exam), covering hands-on patient care skills
- Administrative medical assisting: 56 questions (26.7%), covering scheduling, records, billing, and office management
- Anatomy and physiology: 44 questions (20.9%), testing foundational body system knowledge
- Clinical procedural tasks: 39 questions (18.6%), focused on lab work, specimen handling, and clinical techniques
The heaviest portion of the exam is patient interaction, reflecting how much of the job involves direct communication and hands-on care. Once certified, RMAs must earn continuing education points every three years to maintain their credential.
RMA vs. CMA: Which Carries More Weight
The other major medical assistant certification is the CMA (Certified Medical Assistant), offered by the American Association of Medical Assistants. It was established in 1963, about a decade before the RMA, and is often considered the “gold standard” of medical assistant certifications due to its stricter eligibility criteria and longer track record.
Both credentials hold accreditation from the National Commission for Certifying Agencies, which means neither is a lesser certification in terms of legitimacy. In practice, some employers prefer one over the other based on regional hiring norms. The CMA tends to be more widely recognized and may carry more weight in competitive job markets. That said, the RMA is accepted by employers across the country, and many hiring managers treat the two as interchangeable.
If you’re choosing between them, consider which program is more accessible to you and what employers in your area tend to request in job postings. Either credential qualifies you for the same types of positions.
Pay and Job Outlook
The median annual wage for medical assistants was $44,200 in May 2024, which works out to about $21.25 per hour. That figure covers both certified and uncertified medical assistants, though holding an RMA or CMA credential typically improves your earning potential and hiring prospects compared to working without certification.
Medical assisting remains one of the faster-growing healthcare occupations. The combination of an aging population, expanding outpatient care, and physician practices needing flexible support staff keeps demand steady. For someone looking to enter healthcare without a four-year degree, the RMA credential offers a relatively quick path into a role with consistent employment opportunities and room to specialize in areas like dermatology, cardiology, or pediatrics over time.
