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.
To report issues and incidents of fraud, including but not limited to: content compromise, sharing of test content, breaches of test integrity and or testing contract, please contact the Department of Testing Services at TestSecurity@ada.org.

Examination fees are nonrefundable and nontransferable. There are no exceptions. Your credit or debit card will be charged when you submit your application.
The name on your IDs must match exactly the name on your application or you will be denied admission to test. If you are denied admission, you will need to submit a new application. Your previous fee will be forfeited.
Electronic Notification of NBDHE Eligibility
The timeline for processing your application depends on your status as an applicant. The eligibility requirements are outlined in the Guide. Once your application has been processed, you will receive an email notification concerning your eligibility to test and instructions for scheduling an appointment. Please check your spam folder if you are unable to locate the notification.
Schedule a Time to Take the Examination
Schedule a testing appointment with Pearson VUE 60 to 90 days before your desired exam date. Please remember, you may schedule your examination appointment with Pearson VUE only upon receipt of your eligibility notification.
Rescheduling Examination Appointments
Reschedule your examination appointment by contacting Pearson VUE at least 24 hours before your appointment. The rescheduling fee is $25. Reschedule an appointment by contacting Pearson VUE at 888.456.2830 or at www.pearsonvue.com. Leaving a message for a local test center is not sufficient; the local test center cannot schedule, reschedule, or cancel your appointment.
If you need to cancel or reschedule your appointment due to an emergency please contact the Department of Testing Services by emailing firstname.lastname@example.org or calling 800.232.1694.
Take the Exam at a Pearson VUE Test Center

Schedule Change Information
The schedule change for each of the National Board Examinations is now in effect.
An optimal 15-minute scheduled break has been added to each section of the National Board Examinations.
Please download and read about the schedule change information in the respective National Board Guides
This change does not affect the total testing time required for the examinations, with the exception of adding 15 minutes to Day 2 of the NBDE Part II. To compensate for the additional 30 minutes of break time, the optional scheduled lunch break has been shortened from 60 minutes to 30 minutes. Please make any necessary preparations and adjustments in anticipation of the shortened lunch break.
The additional breaks occur after a specified number of questions have been answered, NOT according to the amount of time that has elapsed. Once you have answered the questions, you must review your answers to those questions before taking the optional 15 minute break. You will NOT be able to return to the first set of questions after you have finished the review. Candidates who have been granted additional time as part of a testing accommodation will not receive additional scheduled breaks, but can instead be granted additional unscheduled breaks.
Joint Commission data suggest that examinees tend to spend more time on patient case testlets than on standalone items. Please make sure to pace yourself appropriately as you work through the examination, noting in particular the presence of testlets in examination sections. As a reminder, you may access your locker during scheduled breaks, but NOT during unscheduled breaks. Accessing your locker during an unscheduled break can result in the voiding of your scores and a mandatory retest wait period of up to two years.
