Format and Content
The Written Examination is administered in two books of 150 multiple choice questions. Each book is given in a 150 minute session.
The sessions are held in the morning and afternoon of one day.
The Written Examination Protocol provides specific details regarding the format and scheduling of the examination.
Written Examination items are developed based on the Competencies for a Beginning Dental Practitioner in Canada.
The NDEB updates examination and assessments questions on a regular basis as new knowledge becomes available.
Examinations administered in 2021 will use the 2018 American Academy of Periodontology (AAP) disease classification. The 1999 AAP old term may be included in brackets after the new term when applicable.
Example: supracrestal tissue attachment (biologic width)
Written Examination Protocol
Protocols contain important information regarding the Written Examination. This document should be read carefully.
Score sheets are electronically scanned and processed. Results are then verified manually at least three times. An additional verification is done of all results close to the passing score before they are released to candidates.
A test equated, re-scaled score of 75 or greater is reported as a Pass. A test equated, re-scaled score of less than 75 is reported as a Fail and will include the test equated, re-scaled score. No further breakdown of results is available.
In order to ensure the consistency of scores on all versions of the examination, the NDEB uses a test equating and rescaling procedure. This procedure correlates the established passing score on a standardized reference examination with the current version of the examination and determines the standardized mark. The NDEB maintains a standardized passing score of 75 on all assessments and examinations.

You can take the Written Examination a maximum of three times.
