The AMT Registered Medical Assistant (RMA) exam has 210 questions, a 120-minute time limit and a passing score of 70 on a scale of 0-100. Its content falls into four areas, and clinical patient interaction is the heaviest at 33.8%. This guide shows how the exam is built and how to plan your study around it.
If you want to see where you stand before you read further, start the RMA practice test and treat your first score as a baseline. The rest of this article explains what that score should be compared against.

What does the RMA credential show, and who can sit the exam?
A medical assistant works in two worlds at once. In the morning that may mean checking a patient in, verifying insurance and keeping the schedule moving. An hour later it may mean taking vital signs, preparing a room or setting up an instrument tray. The Registered Medical Assistant credential from American Medical Technologists (AMT) is built around that mix. It tells an employer that you passed a standard exam covering both the front office and the clinical side of an outpatient practice.
AMT is the certifying body, and its own page for the credential is the place to confirm anything that can change. At the time of writing, AMT's Medical Assistant (RMA) page says that all applicants must pass the AMT examination for RMA to become certified. It also says that applicants must meet one of its eligibility routes before they can apply.
