The Complete Guide to the ADC Written Exam
The ADC Written Examination is the second stage of the Australian Dental Council's assessment pathway for internationally qualified dentists seeking general registration in Australia. It is a demanding, knowledge-based exam that gates entry to the practical examination — so understanding exactly what it assesses, and preparing along the official blueprint, is the difference between one attempt and several.
Where the Written Exam fits in the ADC pathway
For most overseas-trained dentists, registration in Australia runs through three ADC stages: an Initial Assessment of your qualifications, the Written Examination, and finally the Practical Examination. You must pass the Written Examination before you can sit the Practical Examination.
The Written Examination tests whether your underpinning clinical knowledge meets the standard of a graduating Australian dentist. It is broad: it spans diagnosis, management planning, treatment and the professional and health-promotion competencies expected of a safe practitioner.
Format of the exam
The Written Examination is computer-delivered over two consecutive days. It contains 280 questions arranged as 56 clinical scenarios with five questions per scenario. There are four sections — two each day — with 70 questions and two hours per section.
A proportion of the questions are unscored pilot items being trialled for future exams; these are indistinguishable from scored questions, so you should treat every question as if it counts. Because the exam is scenario-driven rather than recall-driven, success depends on clinical reasoning, not memorisation alone.

What the exam tests
Content is mapped to the ADC's professional competencies and is weighted across five domains and thirteen clinical disciplines. The two diagnostic domains — clinical information gathering and diagnosis & management planning — carry the most weight, which tells you where to invest your study time.
We break the full weighting down, domain by domain and discipline by discipline, in our ADC Written Exam syllabus & blueprint guide.
How to prepare
The candidates who pass efficiently do three things: they study along the blueprint weighting (not evenly), they practise with scenario-style questions rather than flashcards, and they retest their weak areas until they are no longer weak. A timed full-length mock exam in the final weeks calibrates pacing and stamina.
Our step-by-step study plan walks through a realistic timeline and the weekly routine that gets you there.
Frequently asked questions
Is the ADC Written Exam multiple choice?
Yes. It is a computer-based exam made up predominantly of single-best-answer multiple-choice questions built around clinical scenarios.
How many sections is the ADC Written Exam and how long does it take?
The Written Examination runs over two consecutive days with four sections in total — two each day. Each section contains 70 questions and lasts two hours.
Do I have to pass the Written Exam before the Practical Exam?
Yes. In the ADC assessment pathway you must pass the Written Examination before you are eligible to sit the Practical Examination.
How long should I study for the ADC Written Exam?
Most candidates prepare over three to six months. The right length depends on how recently you graduated and how much time you can commit each week — the key is consistent, blueprint-weighted practice rather than cramming.
