Prerequisites for taking the CDT certification exam

You might need a few prerequisites before taking the test:


The requirement for exam eligibility is a high school diploma. If so, you frequently need to combine your education with five years of relevant experience or training. To begin your training, many facilities require an associate’s degree or higher. You could enroll in a program approved by the Commission on Dental Accreditation (CODA) to pursue these degrees. The American Dental Association’s (ADA) department is called CODA. Even though it is not necessary, formal education can help you gain the knowledge you may need for the written and practical exams.


Depending on your path to certification, your professional experience in dental technology may vary. Here are some requirements for each path:

RG exam

You can take the Registered Graduate exam a year after graduating from a program, whether it is accredited or not. By putting your knowledge and skill in the field of dental technology to the test, you can gain experience at the entry-level. This test consists of written portions for the comprehensive, specialty, and practical exams. You have four years to finish the other two parts after passing the first exam.

Application and fees

Each part of the CDT exam requires payment and application completion. Your basic contact information and documentation that you have the necessary training or work experience are included in the application. Each portion of the exam requires its own fees. If you take the practical exam abroad, you might have to pay extra for the shipping of the materials and molds. Your CDT exam application and fees can be submitted online or by email.

What does the CDT certification exam include?

There are several key components of the CDT certification exam:

Written exam

A computer-based test called the written exam is available online for prospective dental technicians to take. There are remote proctors, which need a number of things to be completed, including a private computer, a quiet workspace, and a mobile monitoring application. Basic subjects like theory and terminology, oral anatomy, health and safety, and materials science are covered in the written comprehensive exam. Participants have two hours and 45 minutes to complete the 160-question test.

Written specialty exam

Your chosen specialization, such as ceramics or implants, will be the subject of the written specialty exam. This exam can be scheduled to be taken remotely on a personal computer with a virtual proctor, just like the written comprehensive exam. This exam is shorter (80 questions) than the other written exam, and you have one hour and a half to finish it. Additionally, they use the field questions on this test to collect information about the types of questions they should include on future exams.

Practical exam

Practical exams demonstrate how you can apply your knowledge through simulations and laboratory work. These can be finished locally in a group setting or remotely using a virtual proctor. You complete this exam within five hours and 15 minutes. Although NBC sends you the necessary tools, including articulators and molds, they advise bringing your own equipment. You might need to carry out several tasks to demonstrate your proficiency depending on your specialty. You can return the finished products to the company for a competency assessment. With the in-person exam, you deliver your finished materials there for evaluation.
