The exam assesses candidates’ clinical, administrative, and general knowledge competencies essential for medical assistants in healthcare settings.

What is a certified medical assistant?

A Certified Medical Assistant (CMA) is a trained healthcare professional who has completed medical assisting education, earned a CMA credential from the AAMA, and supports physicians in outpatient settings by handling assigned tasks in a healthcare facility. CMAs perform both clinical and administrative tasks; clinical responsibilities are directly related to patient care, such as taking vital signs, recording medical histories, preparing exam rooms, and administrative duties include scheduling appointments, greeting patients, updating medical records, verifying insurance, billing, coding, etc., to keep the regular workflow organized.

According to the AAMA’s official website, there are currently 68,495 active CMAs, with more scheduled to take the exam, and a 69% first-time pass rate. This indicates steady professional demand and growth because of CMAs’ importance in multitasking on both clinical and administrative sides, balancing front and back office functions, forming liaisons among patients, family members, insurance companies, providers, and specialists, and maintaining day-to-day organizational operations.

How long does it take to become a certified medical assistant?

It takes about 2 months to 2 years to become a certified medical assistant, depending on the program path you choose. An accelerated program takes 2 to 4 months, a diploma program takes 9 to 12 months, and an associate degree takes 18 to 24 months. Shorter programs focus on essential clinical and administrative skills for faster job entry, while diploma and associate degree programs include those same skills, plus general education courses, for a broader foundation and greater long-term flexibility.

A diploma program (9 to 12 months) is designed for students who want to enter the workforce quickly with focused training.

What is the certified medical assistant exam?

The certified medical assistant (CMA) exam is a national test administered by the American Association of Medical Assistants (AAMA) to measure whether a candidate has the knowledge and skills needed to work as a competent medical assistant. It is designed to verify both clinical and administrative competence, so passing it shows that the candidate is prepared for the healthcare industry.

A candidate must first meet AAMA eligibility requirements to sit for the exam, which include graduating from an accredited medical assisting program and, in many cases, completing required supervised practical training or externship hours. Once eligible, the candidate applies through the AAMA and schedules the computerized exam, which is offered in a timed testing format.

The CMA exam includes 200 multiple-choice questions: 180 scored and 20 unscored pretest questions. It is completed in four timed sections over a 4-hour appointment. A score of 405 is required to pass, and the credential stays valid for 60 months before recertification is needed.

The exam topics focus on the core duties of a medical assistant, so candidates should expect questions on vital signs, medical terminology, patient preparation, documentation, infection control, communication, ethics, billing, and insurance.

The CMA exam costs $125 for AAMA members and qualifying recent graduates, while nonmembers and other eligible categories pay $250. The exam is taken in a multiple-choice, computerized format, and the best way to prepare is to review the AAMA exam outline, study clinical and administrative topics, and practice with sample questions and timed practice tests.
