Certifying examinations

The online certifying examinations are computer based and consist of 65 - 70 questions. 75% of the questions will be electronically answered, and 25% will need to be answered on a paper exam sheet.

The exams consist of a range of question types for the computer-based exams, including:

  • Multiple choice/single choice (one correct answer from a range of possible answers)
  • Inline (select a word/phrase to complete a statement)
  • Numerical
  • Multi-select (select the number of correct answer options)

The paper-based questions will require the candidate to draw, design or fill in answers on a diagram, much like the current plumbing, gasfitting and drainlaying examinations.

The exam lasts for two and a half hours and costs $410.00 (GST inclusive).

Reference materials will be supplied to candidates as a PDF within the exam, if you require hard copies of the codes and standards when sitting your exam, you will need to apply for special conditions prior to booking your exam with Aspeq.

Assistance can be in the form of one or more of the following:

  • an exam assistant - an exam assistant will read you the exam questions.
  • a separate room – you will be able to sit your exam in a separate room to other candidates
  • 30 minutes extra time
  • hardcopy resources – you can receive hard copy resources instead of referring to resources on your exam computer

Plumbing registration exam papers

Legislation, registration class names, standards and practices mentioned in them were valid at the time of the examinations. These are available for reference only and preparation should be based on up-to-date practices and resources.
