If you have been researching Canadian dental licensure, you have encountered the abbreviation "AFK" — and possibly found it difficult to get a clear answer about what it involves. This page provides that clarity.
What AFK stands for
AFK stands for Assessment of Fundamental Knowledge. It is the first written examination in the NDEB (National Dental Examining Board of Canada) pathway for internationally trained dentists. "Fundamental" refers to the foundational dental knowledge expected of a Canadian dental school graduate — not a specialist, but a competent general dentist ready for independent practice in Canada.
Format
The AFK is a 200-question MCQ exam delivered at Prometric test centres. All questions are single best answer with five options. The exam is approximately four hours in duration. It sits twice per year — typically March and September.
What it tests
The NDEB blueprint divides content into three domains. Biomedical sciences (20 per cent) covers anatomy, physiology, biochemistry, microbiology, and general and oral pathology. Clinical dental sciences (60 per cent) covers oral pathology and medicine, oral surgery, periodontology, restorative dentistry, prosthodontics, endodontics, orthodontics, paediatric dentistry, and pain and anxiety control. Behavioural and community dental sciences (20 per cent) covers ethics, practice management, community dentistry, and epidemiology.
The 60 per cent clinical weighting means clinical dental knowledge is the core of the exam. But the 20 per cent biomedical sciences component is where most candidates lose the marks that separate pass from fail.
Pass rates
AFK pass rates range from 32 to 63 per cent — one of the highest failure rates of any dental licensing examination. The variation between sittings reflects cohort composition rather than changes in exam difficulty.
How to prepare
Four to five months of structured revision with a question bank framed in Canadian dental context. Focus on biomedical sciences first (the most neglected domain), then clinical dental sciences systematically, then behavioural sciences.
iatroX's NDEB AFK bank contains over 1,500 questions covering all three blueprint domains in Canadian context. Adaptive learning targets your weakest areas. All included at £29 per month or £99 per year.
