Inside the NDEB Equivalency Process: What Internationally Trained Dentists Should Know Before Sitting the AFK

Every year, thousands of internationally trained dentists set their sights on practising in Canada. For graduates of non-accredited dental programs, the route runs through the National Dental Examining Board of Canada's Equivalency Process. Understanding that process, and its first gate, the Assessment of Fundamental Knowledge, is the best way to avoid costly mistakes.

The three-exam Equivalency Process

The Equivalency Process comprises three examinations taken in strict order: the Assessment of Fundamental Knowledge (AFK), the Assessment of Clinical Judgement (ACJ) and the National Dental Examination of Clinical Competence (NDECC). According to the NDEB, the AFK is a multiple-choice exam testing biomedical science and applied clinical science knowledge. The ACJ uses single-answer and multi-answer multiple-choice questions, including case-based diagnosis, treatment planning and clinical decision-making. Candidates must pass each exam before moving to the next.

The NDEB also updates its policies. It has announced changes to the registration process for the AFK, the ACJ and the virtual OSCE, and its updated by-laws came into effect on July 1, 2026. Candidates should read the NDEB news page before they register for anything.

What the AFK tests and how it is set up

The AFK consists of 200 single-answer multiple-choice questions delivered in two parts, with two hours for each. It is offered electronically at Prometric test centres and in booklet format at select sites. A candidate may sit it a maximum of three times. Because a passing grade is required before you can continue, the AFK is both a knowledge check and a gate.

In practice, that means breadth matters. The exam spans biomedical sciences and applied clinical science, so weak areas that you rarely used in clinical practice can still cost marks.

Preparing well: materials, questions and mock exams

Good preparation has three parts.

Choose materials that match the exam

Start with what the NDEB publishes about content and format. Then pick one main source for content review. Candidates often collect too many resources and finish none. Well-chosen AFK study materials should be current, aligned with the exam's content and organized so you can track your progress.

Use exam-style questions to learn how the exam thinks

Practice questions should mirror the single-answer format. Read the explanations, not just the answers. When you get a question wrong, ask whether the problem was knowledge, reading or reasoning. AFK exam questions are most useful when you use them to find patterns in your mistakes.

Run timed mock exams

Because the real exam has two two-hour parts, your mock exams should too. Sit them without notes and review them afterwards. Sort errors by discipline and by cause, then plan the next week around the largest group. Do not retake the same paper straight away.

A note on integrity. The NDEB expects candidates to keep exam content confidential. Avoid anyone selling recalled or leaked questions, and check the NDEB's current policies. Preparation built on the exam's stated content areas is safer and more effective, and it protects your standing with the regulator.

Common mistakes at the AFK stage

• Studying only what you know well. It feels good, but the marks are in your weakest areas.
• Leaving mock exams too late. If your first full mock is in the last week, there is no time to act on it.
• Underestimating breadth. The exam covers biomedical and applied clinical science, so gaps in either can hurt.
• Registering without a plan. Booking a sitting before you have a schedule creates pressure without preparation.

How to tell a good preparation source from a weak one

With so many options, it helps to have simple tests. A good source is transparent about who created it and when it was last updated. It matches the exam's stated content areas. It gives explanations, not just answers. And it makes no guarantees about your result.

A weak source hides its authors, repeats outdated content or promises a pass. Before you pay, ask for a sample and compare it against what the NDEB publishes. If a provider cannot explain how its questions relate to the exam, keep looking.

Planning your timeline

Work backwards from your target sitting. The NDEB dates page lists sittings and registration windows, and notes that exams can fill before the deadline. Registration dates for individual sittings have changed in the past, so always confirm the current details before you plan around them. Aim to finish your content review with time left for at least two full timed mock exams.

What happens after the AFK?

Passing the AFK does not end the process. The next step is the Assessment of Clinical Judgement, which uses single-answer and multi-answer questions built around cases, followed by the NDECC. Each exam has its own requirements, so it helps to think of the AFK as the start of a longer plan. Candidates who understand the whole route can budget their time and money more realistically, and are less likely to be surprised by requirements further down the road.

Questions candidates often ask

Can I skip the AFK? Not if you graduated from a non-accredited program and are following the Equivalency Process. The exams are taken in order.

How many attempts do I have? A maximum of three for the AFK, according to the NDEB.

Final thoughts

The AFK is the first step on a long route, and a well-planned first attempt saves time and money. Learn the process, choose your materials carefully, practise realistically and respect the rules. Candidates who do that give themselves the best chance of moving on to the next stage.
