The NDEB has been monitoring developments regarding the COVID-19 pandemic across the country. Based on the information available, the NDEB has made the decision to close registration for the August 2020 Assessment of Fundamental Knowledge (AFK).

At this point in time, the NDEB cannot confirm if the August AFK will be able to run as scheduled. We understand that this unknown may be stressful for participants; however, a decision on the administration of the examination must be made considering the health and safety of all concerned. The NDEB is committed to providing information about the August 2020 AFK by June 15

Approved participants can register for the Assessment of Fundamental Knowledge (AFK), by logging on to their online profile.

Format and Content


The AFK is administered in two books of 150 multiple-choice questions. Each book is given in a three hour session. The sessions are held in the morning and afternoon of one day.


The AFK Protocol provides specific details regarding the format and scheduling of the assessment.


The assessment Blueprint outlined below shows the content areas and approximate percentages of questions in each area. 


The NDEB updates examination and assessments questions on a regular basis as new knowledge becomes available.



The NDEB is aware that the American Academy of Periodontology (AAP) published a new disease classification in the Journal of Periodontology in June 2018. All NDEB examinations and assessments will use the previous AAP classification (1999).

The NDEB will notify examinees when the new disease classification is incorporated into its examinations and assessments.


NDEB examinations and assessments use the terminology adopted by the American Association of Endodontists (AAE) in 2009.


The NDEB is aware of the most current guidelines for antibiotic prophylaxis as published in North America and in the reference texts used by Canadian Dental Programs.

Download the 2020 AFK Protocol in PDF format.


Assessment results 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 participants.

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. Results will include the test equated, re-scaled score. No further breakdown of results is available.


Passing Standard

In order to ensure the consistency of scores on all the versions of the assessment, the NDEB uses a test equating procedure. This procedure correlates a standardized reference assessment with the current version of the assessment and determines the standardized mark. The NDEB maintains a standardized passing score of 75 on all assessments and examinations.

You can take the AFK a maximum of three times.
