                                The number of questions on the Registered Dental Assistant (RDA) test can differ significantly depending on the administering organization. For example, the exam issued by American Medical Technologists (AMT) consists of 210 multiple-choice questions, while the California RDA exam administered by PSI has 150 questions. This variation means it is crucial to identify which specific RDA test you will be taking.
