Medical assistant certification exam

There isn't one single medical assistant certification exam. Each certification has its own test, so the one you take depends on which credential you want. The AAMA's CMA has 200 questions, NHA's CCMA has 150 scored questions, and AMT's RMA has 210 questions.

The exams compared

Some exams add pretest questions. Those are trial items, and they do not affect your score. You still answer them with the rest, so they use part of your exam time.
