RMA certification is a nationally recognized credential for medical assistants, awarded by American Medical Technologists (AMT). It stands for Registered Medical Assistant and qualifies you to perform both clinical and administrative tasks in physicians’ offices, hospitals, clinics, and other healthcare settings. To earn it, you must pass a 210-question exam administered by AMT.
What an RMA Actually Does
Medical assistants with RMA certification work on both sides of a healthcare practice. On the clinical side, that means taking vital signs, recording patient histories, drawing blood, administering injections, performing EKGs, cleaning and sterilizing instruments, and preparing patients for exams. On the administrative side, the work includes scheduling appointments, maintaining medical records, billing and coding for insurance, processing referrals to specialists, and handling patient phone calls.
The blend of clinical and administrative responsibilities makes the role unusually varied. In a single shift, you might draw blood from a patient, document their medications in the electronic health record, restock an exam room, and schedule a follow-up appointment. Smaller practices tend to expect you to handle both sides equally, while larger organizations sometimes split the roles between clinical and front-desk medical assistants.
How the RMA Exam Works
The certification exam consists of 210 multiple-choice questions and has a two-hour time limit. The questions cover four content areas, weighted unevenly:
- Clinical Patient Interaction: 71 questions (33.8% of the exam). This is the largest section and covers direct patient care, communication, and safety.
- Administrative Medical Assisting: 56 questions (26.7%). Covers scheduling, records management, billing, coding, and office procedures.
- Anatomy and Physiology: 44 questions (20.9%). Tests your understanding of body systems and how they relate to common conditions.
- Clinical Procedural Tasks: 39 questions (18.6%). Focuses on hands-on skills like phlebotomy, specimen collection, and medication administration.
The heaviest emphasis falls on patient interaction and administrative skills, which together make up over 60% of the test. If you’re planning your study time, those two areas deserve the most attention. AMT publishes a detailed competency outline that breaks each section into specific subtopics, which serves as the closest thing to an official study guide for the exam.
Eligibility Requirements
All applicants must pass the AMT examination to earn the RMA credential. To sit for the exam, you generally need to meet one of several qualification pathways. The most common route is completing a medical assisting program accredited by a recognized agency. Military training in a relevant healthcare field can also qualify you, as can documented work experience as a medical assistant, though specific requirements for the experience pathway vary. AMT reviews each application individually to confirm eligibility before granting access to the exam.
RMA vs. CMA: How They Compare
The other major medical assistant certification is the CMA (Certified Medical Assistant), offered by the American Association of Medical Assistants (AAMA). Both credentials are nationally recognized, cover similar clinical and administrative content areas, and qualify you for the same types of positions. The practical differences come down to exam format, history, and perception.
The CMA exam has 200 multiple-choice questions split across four 40-minute segments, giving you 160 minutes total. The RMA exam has 210 questions in a single two-hour block. Both are multiple choice, but the CMA’s segmented format means you work through one content area at a time rather than moving freely between topics.
The CMA credential has been around since 1963, while AMT has offered the RMA since 1972. That longer track record gives the CMA a slight edge in name recognition. Healthcare professionals often consider the CMA the “gold standard” due to its stricter eligibility criteria, and in highly competitive job markets, some employers prefer it. That said, most employers accept either credential without issue, and in many regions the two are treated as interchangeable. If a job posting says “certified medical assistant,” both the RMA and CMA typically satisfy that requirement.
Salary Expectations
Registered Medical Assistants earn an average of $36,215 per year in the United States, which works out to roughly $17 per hour. The pay range is relatively narrow: the bottom 10% earn about $31,200 annually, while the top 10% reach around $41,625. At the 75th percentile, you’re looking at approximately $37,877 per year.
Where you fall in that range depends heavily on geography, years of experience, and the type of facility. Specialty practices and outpatient surgical centers often pay more than general primary care offices. Urban areas with higher costs of living also tend to offer higher wages, though the gap doesn’t always keep pace with rent and living expenses.
Keeping Your Certification Active
RMA certification operates on a three-year renewal cycle. To maintain your credential, you need to earn 30 continuing education points over that period, at a rate of 10 points per year. AMT runs what it calls the Certification Continuation Program (CCP) to track these requirements. Points can come from a variety of activities, including attending workshops, completing online courses, and participating in professional development through AMT or other approved providers.
If you let your points lapse, your certification becomes inactive. Reactivating it requires catching up on the missed continuing education, so staying on top of the annual 10-point requirement is easier than trying to make up the difference later.
How to Prepare for the Exam
AMT publishes a detailed competency document that lists every topic the exam can cover, broken down by section and subtopic. This is the single most useful resource for structuring your study plan, because it tells you exactly what percentage of the exam each area represents. Since clinical patient interaction alone accounts for a third of the questions, spending a disproportionate amount of time on anatomy flashcards at the expense of patient communication and safety topics would be a mistake.
Beyond the official outline, most candidates use a combination of their program’s textbooks, third-party review books designed for medical assistant exams, and online practice tests. The practice tests are especially valuable for getting comfortable with the pacing. Two hours for 210 questions gives you roughly 34 seconds per question, so you need to read quickly and avoid getting stuck on any single item. If you completed an accredited medical assisting program recently, much of the material will be review. The exam tests competency at an entry-level standard, not expertise, so the goal is broad coverage rather than deep specialization in any one area.
