The national Board


The purpose of the Dental Hygiene National Board is to assist state dental boards in determining the qualifications of individuals who seek licensure to practice dental hygiene as Registered Dental Hygienists or RDHs. The examination assesses the ability to understand information from the biomedical, clinical and/or dental sciences and apply this information in a problem- solving context. State dental boards use the information provided by this examination to help protect the public health when issuing licensure. 
The Dental Hygiene National Board is a written examination. Clinical examinations are given by individual states or testing agencies. Currently, all United States licensing jurisdictions recognize the NBDHE (National Board Dental Hygiene Examination). 
The Joint Commission for National Dental Education is responsible for the development and administration of the Dental Hygiene National Board each year. 
Dental Hygiene Seminars provides students with a focus summary of the information necessary to study for and pass the National Board. Students who attend the DHS National Board review (either in-person or virtually) receive a concise review of each topic presented on the National Board as well as information on study techniques, stress reduction and an overview of the format of the Board. In addition to the information presented at the review courses, DHS offers students an interactive practice Mock Board exam and access to multiple practice questions in each subject area on the DHS app.



Thank you for making this the best money I have ever spent! Thanks to you all – I will pass the Boards!
