The INBDE at a Glance
What is the INBDE?
The Integrated National Board Dental Examination (INBDE) is a new examination for dental licensure that is scheduled to replace the current National Board Dental Examination (NBDE) Part I and Part II examinations.
The INBDE is a two-day examination administered on a computer. Day 1 consists of 360 test items (3 sets of 100 standalone items, 1 set of 60 case questions). Day 2 includes 140 test items (2 sets of 70 case questions). The total exam administration time is 12 hours and 30 minutes, including the tutorial, scheduled breaks, and a survey.
- First INBDE administration: August 1, 2020
- Last administration of the NBDE Part I: Due to COVID-19, this is now October 31, 2020
- The last administration of the NBDE Part II: August 1, 2022
After October 31, 2020, all students who have not completed (or passed) NBDE Part I are expected to take the INBDE. For more information about the NBDE Part I and II exams, visit the American Dental Association website.
Structure of the Exam
The INBDE consists of 500 total items. Previously, students had to complete 900 questions between the NBDE Part I and Part II exams. This new exam will emphasize synthesis and understanding of clinical concepts through integration of dental and basic sciences, rather than rote memorization and recall. Additional focus will be placed on evaluating examinees’ decision-making skills and preparedness for safe, professional practice of dentistry.
The 500 exam questions will cover the Domain of Dentistry, which is represented through a set of Clinical Content areas and Foundation Knowledge areas that are required for the safe, independent, general practice of dentistry by entry-level practitioners. The Domain of Dentistry serves as the key reference for the INBDE test specifications.
Your INBDE Score
The INBDE is scored on a scale of 49-99. A scaled score of 75 or above is considered a passing score. Numeric scores are not expected to be provided to students who pass the examination. Candidates who fail the examination will receive a report of their performance by topic for remediation purposes.
How to register for the INBDE
To be eligible to take the INBDE, your dental school must certify that you have completed the necessary course requirements. Graduates of international dental schools must have their official dental school transcripts verified by Educational Credential Evaluators, Inc.
Important Note: Once you take the INBDE, you are no longer eligible to complete the NBDE Part I and Part II exams.
