What the written examination of the New Zealand Oral Health Therapy Registration Examination (NZOHTREX) covers
Applicants for registration as an oral health therapist must meet the oral health therapy competencies in order to be registered. You must be able to satisfy these competencies, a list of which can be found in the scope of practice competencies for oral health therapists.
Structure of the examination
The written examination consists of four two-hour papers - two relating to restorative activities and two relating to hygiene activities. It assesses your knowledge and understanding of the scientific bases of contemporary oral health therapy and how to apply that knowledge.
Two papers include questions requiring essay and short written answers. Some questions may require you to demonstrate an ability to analyse and evaluate current knowledge. You should note the meanings of the following three terms frequently used in the examination:
- discuss: examine by argument. Involves logical critical appraisal of an issue
- describe: description of characteristics
- write (brief) notes on: short sentences or phrases. Tables, lists and/or diagrams may be used.
The last two terms are often used in questions that enable you to demonstrate your breadth of knowledge.
For these papers you will enter the examination room 15 minutes before you start to write. You will have five minutes to read the instructions and 10 minutes to read the examination questions.
The two remaining papers both contain multiple choice questions and visual interpretation in the form of images and radiographs illustrating clinical conditions with questions requiring short written answers.
