About the Medical Assistant Certification Exam
Medical assistant certification is offered by two major organizations: the AAMA (American Association of Medical Assistants), which grants the CMA, and the AMT (American Medical Technologists), which grants the RMA. Both are nationally recognized and accepted by most employers, and both verify competency across clinical and administrative duties.
The CMA exam is 200 questions over 160 minutes, organized into general, administrative, and clinical content areas, and scored on a 200–800 scale with a passing score around 430. The RMA covers the same competencies with more flexible eligibility. Clinical procedures, pharmacology, and medical law/ethics are the most commonly missed areas.
VoltExam drills all eight content areas with full explanations on every question, simulates the timed exam, and includes a Vital Signs Reference so you can confirm normal ranges at a glance. Certification typically requires renewal every 5 years (CMA) through continuing education or recertification.

Vital Signs Reference — Normal Adult Ranges
Normal ranges show up across clinical questions on both the CMA and RMA. These are standard adult, at-rest values — memorize them cold, then practice spotting out-of-range scenarios.
| Vital Sign | Normal Range (Adult) | Notes |
|---|---|---|
| Blood pressure | Less than 120/80 mmHg | Adult, at rest; 120–129 systolic = elevated |
| Heart rate (pulse) | 60–100 bpm | Resting adult; trained athletes may be lower |
| Respiratory rate | 12–20 breaths/min | Adult, at rest |
| Temperature | 97.8–99.1 °F (36.5–37.3 °C) | Oral; average 98.6 °F / 37 °C |
| Oxygen saturation (SpO₂) | 95–100% | On room air |
Reference values for healthy adults at rest. Pediatric, geriatric, and condition-specific ranges differ — always follow your facility's protocols and provider orders.

Frequently Asked Questions
What is the CMA exam?
The CMA (Certified Medical Assistant) exam is administered by the American Association of Medical Assistants (AAMA). It is 200 questions over 160 minutes, split into three content areas — general, administrative, and clinical. Scores are reported on a 200–800 scaled range with a passing score of approximately 430. The CMA is one of the most recognized medical assistant credentials in the United States.
What is the CMA exam pass rate?
The CMA first-attempt pass rate is approximately 65–70%. The most commonly failed sections are clinical procedures, pharmacology, and medical law/ethics. Candidates with strong clinical training who supplement with targeted practice questions consistently outperform those who rely on class notes alone.
CMA vs RMA — which certification should I get?
Both the CMA (AAMA) and RMA (AMT) are nationally recognized medical assistant credentials accepted by most employers. The CMA is more widely recognized in physician offices and outpatient clinics; the RMA tends to be preferred in multi-specialty practices and has more flexible eligibility requirements. If you graduated from an AAMA-accredited program, you are eligible for the CMA. VoltExam prepares you for either exam.
How long should I study for the medical assistant exam?
Most candidates study 30–60 hours over 4–8 weeks after completing their training program. Focus on clinical procedures, pharmacology, and the topics you scored lowest on in practice tests. Short, frequent practice sessions with explanations retain better than cramming — many candidates study 2–3 hours per week with VoltExam.
