What Is the Registered Dental Assistant Exam?
The RDA is issued by American Medical Technologists (AMT) and is one of the most common dental assistant exams. The exam is used to assess whether or not candidates have the knowledge and skills necessary to perform the duties of an entry-level dental assistant.
The RDA exam is a computer-based test that consists of 210 multiple-choice questions. Some states may offer or require additional state board exams as well. Though you can work as a dental assistant without certification, the RDA exam can position you for a more successful long-term career.
Passing the exam signifies to employers that you have the necessary skills and knowledge to work as a dental assistant and allows you to obtain your Registered Dental Assistant Certification.
Registered Dental Assistant Exam Requirements
Before you can apply to take the Registered Dental Assistant exam, there are a few accomplishments you’ll have to check off your list first.
1 – Graduate from high school.
To be eligible for the RDA exam, you’ll need a high school diploma or equivalent.
2 – Complete an accredited dental assistant certification program.
You’ll also need to complete an accredited dental assisting program before taking the RDA exam. Online dental assisting programs typically last between 3 and 6 months and cover topics like infection control, chairside procedures, and radiography.
Your program must be accredited by an agency approved by the US Department of Education (DOE), the Council for Higher Education Accreditation (CHEA), or the AMT Board of Directors.
If you still need to complete an accredited dental assisting program, now is the time to start researching your options.
Or, follow one of these other pathways:
-
Complete a military dental assisting training program plus one year of work experience in a dental assistant role.
-
Gain three years of work experience employed as a dental assistant.
3 – Obtain your CPR certification.
You’ll need to show proof that you’re CPR certified before you can take the RDA exam. Some dental assisting programs will include CPR certification as part of the curriculum.
But if yours doesn’t, you can easily obtain CPR certification through the American Heart Association, the Red Cross, or another approved provider. Finally, be sure to complete a program that includes an in-person skills assessment.
