RG Application & Exam Process

The Recognized Graduate (RG) designation is the first step in obtaining a Certified Dental Technician (CDT) designation. The goal of the RG examination is to measure competency of a predetermined body of knowledge as well as a means of validating a formal education against a national third party standard. To become an RG, a technician must demonstrate their knowledge by successfully taking and passing the RG Exam within one (1) year of graduation from a formal dental laboratory technology program.


The Examinations

The examinations given by the NBC are the result of years of continuing development. Questions on the exams originate with technicians in the field. Subject matter experts conduct regular reviews, revisions and updates of the exams. All examination content is also subject to ongoing statistical analysis based on actual usage of exam questions as well as peer review to ensure relevance to current practices in dental technology.
