An MA certification is a professional credential that validates a medical assistant’s knowledge and skills in clinical, administrative, and general healthcare tasks. It’s earned by passing a nationally recognized exam, and while not legally required in most states, it significantly boosts hiring potential and pay. Certified medical assistants earn roughly 22% more per hour than their uncertified counterparts.
What MA Certification Covers
Medical assistant certification proves you can handle the full scope of what the job demands: taking patient vitals, assisting with procedures, drawing blood, managing medical records, processing insurance claims, scheduling, and communicating effectively with patients and providers. The certification isn’t tied to one narrow skill set. It covers the blend of clinical and office work that defines the medical assistant role.
Several organizations offer MA certifications, but a few dominate the field:
- CMA (AAMA): The Certified Medical Assistant credential, issued by the American Association of Medical Assistants. This is widely considered the gold standard. Its certification program is accredited by the National Commission for Certifying Agencies (NCCA).
- RMA (AMT): The Registered Medical Assistant credential, issued by American Medical Technologists.
- CCMA (NHA): The Certified Clinical Medical Assistant credential, issued by the National Healthcareer Association. This one leans more heavily toward clinical skills.
- NCMA (NCCT): The National Certified Medical Assistant credential, issued by the National Center for Competency Testing.
All four are nationally recognized, but the CMA and RMA tend to carry the most weight with employers. Healthcare systems like Children’s Minnesota, for example, specifically note that medical assistants holding CMA or RMA credentials have opportunities to move into lead roles.
What the CMA Exam Looks Like
The CMA (AAMA) exam is the most widely taken MA certification test, so it’s a useful benchmark for understanding what these exams involve. It consists of 200 multiple-choice questions, though only 180 are scored. The remaining 20 are pretest questions being evaluated for future exams, and you won’t know which ones they are.
The scored questions break down into three categories. Clinical competency makes up the largest share at 59%, covering patient intake, safety and infection control, clinical procedures, and pharmacology. General knowledge accounts for 21%, focusing on legal and ethical issues plus communication skills. Administrative knowledge rounds out the remaining 20%, testing billing, coding, insurance processing, appointment scheduling, and health information management.
That heavy clinical weighting reflects the reality of the job. Most of your day-to-day work as a medical assistant involves direct patient interaction and clinical tasks, so the exam tests accordingly.
Eligibility Requirements
To sit for the CMA (AAMA) exam, you need to have completed a medical assisting program accredited by either CAAHEP (Commission on Accreditation of Allied Health Education Programs) or ABHES (Accrediting Bureau of Health Education Schools). These programs typically take one to two years and include a clinical practicum where you gain hands-on experience in a real healthcare setting. You can earn either a certificate, diploma, or associate degree through these programs.
Other certifications have slightly different entry paths. The RMA and CCMA may accept a combination of education and work experience, making them accessible to people who learned on the job rather than through a formal program. The specific requirements vary by credentialing organization, so it’s worth checking directly before committing to a study plan.
What Certification Costs
The CMA (AAMA) exam fee is $125 for AAMA members and $250 for nonmembers. That membership discount is substantial enough that joining the AAMA before registering often makes financial sense. The NHA’s CCMA exam also requires a fee at registration, though the exact amount varies by how you access the test (through a school program versus independently).
Beyond the initial exam, you’ll pay for ongoing maintenance. The NHA charges about $8 per month to keep your CCMA credential active. The CMA requires recertification every 60 months, which involves completing continuing education rather than paying a flat monthly fee. These costs are modest relative to the salary bump certification provides.
How Certification Affects Your Pay
The financial case for certification is straightforward. In salary survey data comparing over 300 medical assistants, certified MAs averaged $21.44 per hour while uncertified MAs averaged $17.59 per hour. That $3.85 hourly difference adds up to roughly $8,000 more per year for full-time work.
The pay gap reflects what employers are willing to pay for verified competence. Many healthcare organizations prefer or require certification when hiring, and some use it as a prerequisite for advancement. A credential signals that you’ve met a national standard, which reduces the employer’s training burden and liability risk.
Keeping Your Certification Active
Certification isn’t a one-time achievement. The CMA (AAMA) requires recertification every 60 months (five years). To recertify through continuing education, you need 60 continuing education units (CEUs) spread across that five-year window. CEUs can come from approved courses, workshops, conferences, and college coursework related to medical assisting.
Your certification stays current for 60 months from the end of the calendar month when you initially certified or most recently recertified. If you let it lapse, you may need to retake the exam rather than simply submitting CEUs, so staying on top of the timeline matters. Many MAs spread their continuing education across the full five years rather than cramming it all at the end, taking a few courses or attending a conference each year to stay current and avoid last-minute stress.
Do You Actually Need It?
Most states don’t legally require medical assistants to hold certification. You can technically work as an MA without one. But “not required” and “not important” are very different things. Employers increasingly prefer certified candidates, and some large healthcare systems won’t consider applicants without credentials. National certification enhances employment opportunities across the board, and it opens doors to lead and supervisory positions that are otherwise closed.
If you’re weighing whether the investment is worth it, consider that the exam fee pays for itself within a few weeks of earning the higher certified salary. The continuing education requirement also keeps your skills current in a field where clinical guidelines, billing codes, and technology change regularly. For most medical assistants, certification is less of an optional bonus and more of a practical necessity for building a sustainable career.
