TL;DR
The CMA (Certified Medical Assistant) exam by AAMA and RMA (Registered Medical Assistant) exam by AMT are the two primary Medical Assistant certifications. The CMA has 200 multiple-choice questions over 4 hours covering clinical procedures, anatomy and physiology, pharmacology, administrative tasks, and general medical knowledge. The RMA has a similar structure with 200 questions. Both require graduation from an accredited MA program. Pass rates hover around 65–75% for first-time candidates. The exams are broad — covering everything from phlebotomy technique to insurance billing — so a structured study plan that covers all domains is essential.
How to Pass the Medical Assistant Certification (CMA/RMA) in 2026
| Questions | 200 multiple-choice |
| Time allowed | 4 hours (CMA); 3 hours (RMA) |
| Passing score | 430/500 scaled (CMA); ~70% (RMA) |
| First-time pass rate | ~65–75% |
| Certification renewal | Every 5 years (CMA); every 3 years (RMA) |
| Average salary | $38,000–$44,000/year |
Medical Assistant certification validates your competency across the full scope of the MA role — both clinical and administrative. This breadth is what makes the exam challenging. You need to know how to take blood pressure, give injections, perform an EKG, process lab specimens, AND understand medical billing codes, HIPAA regulations, appointment scheduling, and medical records management.
The CMA exam (administered by the AAMA) is structured around three major domains: General (medical terminology, anatomy, professionalism, communication, legal/ethics), Administrative (scheduling, records management, financial management, insurance processing), and Clinical (vitals, injections, specimen collection, diagnostic testing, pharmacology, emergency procedures). Each domain carries roughly equal weight.
The RMA exam (administered by AMT) covers similar content organized slightly differently. Both are nationally recognized, and most employers accept either credential. Your choice between CMA and RMA may depend on which your program prepared you for and which is more common in your area.
Study Schedule
Week 1: Clinical Procedures
- -Review vital signs — techniques, normal ranges, documentation
- -Study injection techniques — IM, SubQ, intradermal — sites, angles, equipment
- -Review specimen collection — phlebotomy, urinalysis, throat culture
- -Study EKG — lead placement, normal sinus rhythm, common arrhythmias
- -Review wound care — cleaning, dressing types, suture/staple removal
- -Complete 2 adaptive sessions on clinical modules
Week 2: Anatomy, Physiology, and Pharmacology
- -Review body systems — cardiovascular, respiratory, digestive, nervous, musculoskeletal, urinary, endocrine
- -Study medical terminology — prefixes, suffixes, roots, combining forms
- -Review common pathophysiology — diabetes, hypertension, asthma, CHF, COPD
- -Study drug classifications — names, actions, side effects, contraindications
- -Review dosage calculations — ratio-proportion method, metric conversions
- -Complete 2 adaptive sessions on anatomy and pharmacology modules
Week 3: Administrative and Laboratory
- -Study medical records management — EHR, documentation standards, corrections
- -Review billing and coding basics — ICD, CPT, CMS-1500
- -Study appointment scheduling — types, matrix, referrals
- -Review HIPAA — privacy rule, security rule, patient rights, PHI
- -Study laboratory procedures — phlebotomy, urinalysis, hematology, CLIA waived tests
- -Complete 2 adaptive sessions on admin and lab modules
Week 4: General Knowledge and Review
- -Study medical law and ethics — scope of practice, standard of care, malpractice, negligence
- -Review infection control — standard precautions, hand hygiene, sterilization, biohazard waste
- -Study communication — patient education, cultural competence, barriers, therapeutic communication
- -Complete 2 adaptive sessions on general modules
Week 5: Full Review and Exam Simulation
- -Take 2 full timed mock exams — simulate real test conditions (4 hours)
- -Review all incorrect answers and categorize by domain
- -Do targeted topic drills on your 3 weakest modules
- -Review dosage calculation problems — these are commonly missed
- -Review exam logistics — test center rules, what to bring, timing strategy

Focusing only on clinical skills
The administrative portion (billing, scheduling, records, HIPAA) is weighted equally with clinical skills. Many candidates feel confident about clinical procedures but are surprised by detailed billing code questions or HIPAA scenarios. Study all domains equally.
Skipping pharmacology
Drug classifications, side effects, interactions, and dosage calculations are heavily tested. You need to know major drug classes (antihypertensives, antibiotics, analgesics, anticoagulants, etc.), their common generic and brand names, and key side effects. Dosage calculations require practiced math skills.
Not memorizing medical terminology
Many questions can be answered correctly just by breaking down the medical term. If you know that "hyper-" means excessive, "-emia" means blood, and "brady-" means slow, you can figure out the meaning of terms you haven't seen before. Invest time in root words, prefixes, and suffixes.
Confusing scope of practice
Know what MAs CAN and CANNOT do. MAs cannot diagnose, prescribe, perform invasive procedures beyond their scope, or make clinical decisions independently. Many questions test whether you know to refer to the physician rather than act independently.
Weak dosage calculations
Dosage calculation questions are essentially math problems. Master the ratio-proportion method and metric conversions (mg to g, mL to L, lb to kg). These are guaranteed points if you practice, and guaranteed misses if you don't.
Score Targets
The CMA exam requires a scaled score of 430 out of 500 to pass (approximately 70% correct). The RMA exam also uses scaled scoring with a similar passing threshold.
Aim for 75–80% on practice tests to ensure you pass comfortably. The scaling can work in your favor or against you depending on question difficulty, so don't aim for exactly the minimum.
On Valenke's readiness report, target "Ready" status in all three major domains (Clinical, Administrative, General). If any domain shows "Developing," that's where you need to focus. A strong clinical score won't compensate for a failing administrative score — you need adequate performance across all areas.
Exam Day Checklist
- The exam is 4 hours — pace yourself at about 1 minute per question with 20 minutes for review
- For pharmacology questions, eliminate answers with obviously wrong drug classifications first
- For dosage calculations, write out your math on scratch paper and double-check before selecting an answer
- For "what should the MA do first" questions, the answer usually involves patient safety or assessment before treatment
- Read every answer choice before selecting — the first "correct-looking" answer may not be the BEST answer
- For HIPAA questions, the most restrictive interpretation of privacy rules is usually the correct answer
