Getting a medical assistant certification involves completing an eligible training program or meeting work experience requirements, then passing a national exam. The entire process takes anywhere from a few months to two years depending on the path you choose. Three main credentials dominate the field: the CMA from the American Association of Medical Assistants, the CCMA from the National Healthcareer Association, and the RMA from American Medical Technologists.
Three Main Certifications to Choose From
Each credential is nationally recognized, but they differ in eligibility requirements, cost, and how employers perceive them.
The CMA (AAMA) is widely considered the gold standard. It requires graduation from a medical assisting program accredited by CAAHEP or ABHES, which are the two bodies that evaluate training programs. The exam costs $250, or $125 if you’re a member of the AAMA or graduated from an accredited program. This is the most restrictive path because it ties eligibility directly to your school’s accreditation status.
The CCMA (NHA) offers more flexibility. You’re eligible if you’ve completed a medical assistant training program within the last five years, or if you have one year of supervised work experience within the last three years (or two years within the last five). You need a high school diploma or GED either way. The exam fee is $177. This is a strong option if you’ve been working in a clinical setting without formal schooling.
The RMA (AMT) is the least expensive at $120. It also accepts candidates through multiple pathways, including formal training and work experience. Many employers treat the RMA and CMA as interchangeable, though some job postings specifically request one or the other.
Education Requirements by Path
If you’re starting from scratch, you’ll need to complete a medical assisting program. These come in two formats: certificate programs and associate degree programs.
Certificate programs are the faster route. A typical program runs about 12 months, or roughly three semesters, and requires around 33 credits. You’ll cover clinical skills like taking vitals, drawing blood, performing EKGs, and administering injections, alongside administrative skills like medical billing, coding, scheduling, and managing electronic health records. Most programs include an externship where you work in a real clinic under supervision.
Associate degree programs take about two years and run 60 to 63 credits. The extra time goes toward general education courses like anatomy, English composition, and psychology. The associate degree doesn’t change what you’re certified to do, but it can give you an edge in competitive job markets and provides a foundation if you later want to pursue nursing or health administration.
If you’re aiming for the CMA specifically, your program must be accredited by CAAHEP or ABHES. Check accreditation status before you enroll. Graduating from a non-accredited program won’t disqualify you from all certifications, but it will lock you out of the CMA exam. The AAMA maintains a searchable directory of accredited programs on its website.
The Work Experience Route
You don’t necessarily need formal education to get certified. The CCMA and RMA both accept candidates who’ve gained their skills on the job. For the CCMA, you need at least one year of supervised medical assisting experience within the past three years, or two years within the past five. You still need a high school diploma or GED.
This path works well for people who started as front desk staff or clinical aides in a physician’s office and gradually took on more responsibilities. The key word is “supervised,” meaning you worked under a licensed provider who can verify your experience. If you’ve been doing medical assisting work but your title was something else, check with the certifying body to confirm your experience qualifies before paying exam fees.
What the Certification Exam Covers
All three major exams test both clinical and administrative knowledge. Expect questions across several broad categories: patient intake and documentation, infection control and safety, pharmacology basics, anatomy and physiology, diagnostic testing, medical law and ethics, insurance processing, and billing and coding. The exams are multiple choice and typically take two to three hours.
Clinical questions focus on the hands-on skills you’d use in an exam room. You’ll need to know proper technique for phlebotomy, how to prepare patients for procedures, when to recognize abnormal vital signs, and how to handle specimens. Administrative questions cover scheduling, referrals, prior authorizations, HIPAA compliance, and the revenue cycle from patient check-in to claim submission.
Most training programs build exam prep into their curriculum, but standalone study guides and practice exams are available from each certifying organization. The NHA offers a structured prep package for the CCMA. For the CMA, the AAMA sells a practice exam that mirrors the real test format. Giving yourself four to eight weeks of dedicated study time after finishing your program is a reasonable target.
Keeping Your Certification Active
Certification isn’t permanent. The CMA requires recertification every 60 months (five years). You need 60 continuing education units during that period, which breaks down to about 12 per year. If you fall short on CEUs, you can recertify by retaking and passing the exam instead. Continuing education can come from approved online courses, conferences, college coursework, or employer-sponsored training.
The CCMA and RMA have similar renewal cycles and continuing education requirements, though the specific numbers differ. Budget a few hundred dollars over each five-year cycle for CE courses and renewal fees.
Why Certification Matters for Your Career
Medical assistants aren’t required to hold a national certification in every state. Scope of practice laws vary significantly, and some states don’t even mention medical assistants by name in their regulations, classifying them instead as unlicensed personnel. That said, certification has become a de facto hiring requirement at most hospitals, large physician groups, and outpatient clinics. Many employers won’t interview candidates without it.
Certified medical assistants also tend to earn more. The median annual wage for medical assistants was $44,200 in May 2024, according to the Bureau of Labor Statistics, and certified professionals typically land on the higher end of that range. Employment in the field is projected to grow 12 percent from 2024 to 2034, which is much faster than average. Ambulatory care centers, specialty practices, and urgent care clinics are driving much of that demand.
Choosing the Right Path for Your Situation
If you have no healthcare experience, enroll in a CAAHEP- or ABHES-accredited program and sit for the CMA exam when you graduate. This combination gives you the broadest recognition and the fewest complications with employer requirements. A certificate program gets you working in about a year.
If you’re already working in a medical office and want to formalize your skills, the CCMA through the NHA is the most accessible option. You can qualify through work experience alone, the exam fee is moderate, and many employers specifically recognize the NHA credential.
If cost is the primary concern, the RMA at $120 is the most affordable exam. Pair it with a community college certificate program, where tuition often runs between $3,000 and $10,000 depending on your state, and you can enter the field with a relatively small financial investment. Financial aid, including Pell Grants, applies to most accredited programs.
Whichever path you take, confirm three things before committing: that your training program (if applicable) meets the eligibility requirements for your chosen certification, that the credential is recognized by employers in your area, and that you understand the recertification timeline so your credential doesn’t lapse after you earn it.
