Approved participants can register for the Assessment of Fundamental Knowledge (AFK), by logging on to their online profile.
Format and Content
The AFK is a 6 hour examination plus one scheduled 30-minute break. The AFK consists of 300 single-answer multiple choice type questions. Each question has a value of one. The lowest score for any question is zero.
The examination will be administered electronically at Prometric test centres. The NDEB’s e-Exam Orientation should be viewed prior to taking the AFK.
The AFK Protocol provides specific details regarding the format and scheduling of the assessment.
The NDEB updates examination 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).

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.
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.
For more information regarding the processes used to select questions and analyze and test equate assessments and examinations please download Information on Test Equating and question selection.
You can take the AFK a maximum of three times.
