NBDHE General Information

Click the blue box and check back daily for new information.  Important updates for all testing candidates regarding COVID-19  

In anticipation of the upcoming flu season and potential increase in restrictions related to the COVID-19 pandemic, all testing candidates planning to test during the winter months of 2021 should submit their application and schedule a testing appointment as soon as possible. There is no guarantee that appointments will not be canceled or rescheduled should restrictions increase, but this ensures the best selection of available testing appointments. 


The JCNDE recognizes the frustration felt among dental hygiene students, faculty and administrators due to circumstances involving COVID-19. The JCNDE has been working to identify an approach that could expand the opportunities for candidates to take the NBDHE. The JCNDE is currently working to implement the following strategies to address the significant needs present at this time:

  • The length of the NBDHE has been reduced, such that it will now require less than four hours to complete.
  • NBDHE administrations will be permitted at thousands of Pearson VUE Authorized Test Centers located throughout the US, in addition to the 280+ Pearson Professional Centers that are owned and operated by Pearson VUE, that currently administer the NBDHE.

The JCNDE believes that—by reducing the testing appointment length and substantially increasing the number of test centers available to candidates—the current backlog will be addressed by the end of this summer. Candidates will be able to schedule short-form-NBHDE testing appointments roughly 2-to-3 weeks before the implementation date, which is anticipated to occur in mid-July.

More information can be found on the NBDHE Quick Facts (PDF) and Short-Form FAQs (PDF).

Important Note Concerning Periodontics Terminology:

In 2017, the American Academy of Periodontology introduced new classifications. These new classifications will be implemented in the fall of 2021 for the NBDHE. Download the classification information below.

During the transition period, it is recommended that individuals become knowledgeable with both sets of classifications, because individual researchers, practitioners, and existing textbooks can communicate information using either set of classifications. Periodontal educators recommend that individuals refer to the 2017 World Workshop On the Classification of Periodontal and Peri-implant Diseases and Conditions available on the American Academy of Periodontology website
