National Board of Dental Hygiene Examination (NBDHE)
The National Board Dental Hygiene Examination assists dental boards in evaluating qualifications of dental hygienists for licensure. The examination will assess each candidate’s ability to understand important information from basic biomedical and dental hygiene sciences and apply this information in a problem-solving context.
The Joint Commission on National Dental Examinations (JCNDE) is the governing body for the NBDHE, working in collaboration with the Department of Testing Services (DTS). Candidates will take the examination at test centers operated by Pearson VUE, an official vendor of the JCNDE and the DTS.
The NBDHE is intended to fulfill or partially fulfill the written examination requirement for licensure in all states. Please refer to each state board’s website for specific details, clarifications, and updated policies.
