How to prepare for the NDHCE

Start with the official material, close the Canada-specific gaps, and practise application over memorization. Here’s the stack that works.

1. The official practice tests come first

The FDHRC sells four preparatory tests (75 questions each, $37.50 + tax) that run on the real exam engine — the closest thing to the actual test and the only regulator-endorsed resource. Candidates consistently say the real exam felt “very similar” to these, with some case studies almost identical in principle. The most repeated advice:

• Do all four, and treat ≥80% (many target 90%) as your readiness signal.
• Take them close to your exam date, so you’re testing knowledge, not memorizing the tests.
• The 2026 versions reflect the updated blueprint (available from March 2026).

Also free and official: the Sample Questions and the EN/FR Lexicon of exam terms.

2. Commercial courses — useful, but know the caveats

The FDHRC does not endorse any third-party course, and every vendor pass-rate claim is self-reported. With that in mind, here’s how the main options compare:

3. Close the Canada-specific gap

About 70–80% of content overlaps with the US NBDHE, so US material is usable — but it’s wrong on the Canadian specifics that the exam tests. Prioritise these:

• Tooth numbering: Canada uses the FDI two-digit system, not the US Universal 1–32. The single most-cited trap.
• Regulation & ethics: provincial self-regulation, scope of practice, the CDHA Code of Ethics, PIPEDA/privacy law.
• Drugs: Canadian names and the CPS (Compendium of Pharmaceuticals & Specialties).
• Public health & radiation: Canada’s Dietary Guidelines, Health Canada Safety Code 30, Canadian blood-pressure and medical-contraindication norms.
• Indigenous & cultural safety, metric units, and French terminology.

4. The textbook the board writes from

When examiners write an item they cite a source text, and the one most often named by candidates is Darby & Walsh, Dental Hygiene: Theory and Practice — the go-to for periodontology and local anesthesia. Wilkins’ Clinical Practice of the Dental Hygienist is the other core reference. You likely already own both from your program, so re-reading beats re-buying.

5. Study plans that passed

The most common reason people retake: memorizing textbooks instead of practising board-style questions and cases, and doing the official tests too late to act on the results.

6. Exam-day strategy (from candidates)

• Periodontal staging is scored as objective classification — no clinical judgment. Classify strictly by the rules; a single feature can move the whole AAP stage up. Take the data as given and don’t “add information in your head.”
• Read the whole case before answering any of its linked questions.
• In section two, do the case studies first while you’re fresh, then the standalone items.
• Read each question 2–3×; skip-and-return within a section (you can’t return once a section is submitted).
• Study the “why” of every wrong answer, not just the right one.
• If it’s your final attempt, don’t write until you’re ready — deferring to the next-next sitting buys months of preparation.

A last-week checklist

• AAP periodontal staging & grading rules.
• Diabetes treatment thresholds (mmol/L: safe to treat vs. non-invasive only vs. defer).
• Radiography settings — mA vs. kVp and what each changes.
• Common medical conditions and dental contraindications.
• One full official practice test the day before, then rest.
