ExploreAbout this exam
The ADC Written Examination described here is the written stage of the Australian Dental Council assessment pathway for internationally qualified dental hygienists, dental therapists and oral health therapists. The ADC presents itself as the independent accreditation authority for the Australian dental professions, assigned accreditation functions by the Dental Board of Australia under the National Registration and Accreditation Scheme, and states that its work protects the health and safety of the public by ensuring dental practitioners meet the high standards required of dental professionals in Australia. On the ADC's published pathway for these three professions, the written examination sits between the Initial Assessment and the Practical Examination, and it is delivered in English. The ADC states that candidates do not need to complete an English test for any stage of its dental practitioner assessment process, but notes that the written and practical examinations are delivered in English and that ability to communicate effectively is assessed in the practical examination; candidates applying for registration must also meet the Dental Board of Australia English language skills registration standard. Preparation should therefore combine revision of professional practice and treatment within scope, dental hygiene and oral health promotion, biomedical and dental sciences, and professional, legal, ethical and communication standards, including cultural safety.

It is not affiliated with, endorsed by, or published by the ADC, and official details such as item counts, duration, fees, pass standards and dates should always be confirmed directly with the ADC.
What you'll study
About ADC Written (Dental Therapy) preparation
Who is the ADC Written Examination for?
It is part of the ADC assessment pathway for internationally qualified dental hygienists, dental therapists and oral health therapists, sitting between the Initial Assessment and the Practical Examination. The ADC also runs written examinations for dentists and dental prosthetists, which are separate pathways with their own requirements.
What language is the examination delivered in?
The ADC states that the written and practical examinations are delivered in English. You do not need to complete an English test for any stage of the ADC dental practitioner assessment process, but your ability to communicate effectively is assessed as part of the practical examination.
Do I need an English test before applying?
No. The ADC states that you do not need to complete an English test for any stage of the ADC dental practitioner assessment process. Separately, successful candidates applying for registration must meet the Dental Board of Australia English language skills registration standard, so check that standard on the Board's website.
How many questions are there, and how long does it take?
The ADC page content available to us does not state the number of questions, the duration, the pass standard or the fee for this written examination. We have not guessed these figures. Confirm current details with the ADC directly before you plan your sitting or your study timetable.
What content should I study first?
Start with the areas you cannot practise without: biomedical and dental sciences, then assessment and treatment within the dental therapist, hygienist and oral health therapist scope. Add dental hygiene and oral health promotion, then professional, legal, ethical and communication standards including cultural safety. Finish with integrated case scenarios that combine all four.
How should I prepare in the final weeks?
Shift from reading to retrieval. Work through scenario questions under timed conditions, then review every wrong answer to find the underlying gap rather than memorising the option. Practise explaining preventive advice and consent conversations aloud, because communication is assessed in the practical examination that follows.
What are common reasons candidates struggle?
Typical weak spots are shallow preventive and health-promotion reasoning, unfamiliarity with Australian legal and ethical expectations such as consent, confidentiality and cultural safety, and answering from habit rather than reading the whole scenario. Candidates also lose marks by studying only clinical sciences and neglecting professional practice.
Can I retake the written examination if I fail?
The source material available to us does not describe the retake policy, sitting limits or waiting periods for this examination, so we cannot state them. The ADC publishes policies, review and appeals information, and candidate news; check those pages or contact the ADC for the current rules.
Is this page an official ADC resource?
No. This is independent study material and is not affiliated with or endorsed by the ADC. Use it alongside the ADC's own published information, including its assessment standards, handbooks and materials, policies, and frequently asked questions, which remain the authoritative source for process and requirements.
