You must pass the Motor Driving Instructor (MDI) theory test.

The MDI theory test is broken into 2 parts. The first includes eight give-way questions. You must obtain a pass mark of 100% for the give-way questions.

The remainder of the assessment is general road rules, road craft, and MDI roles and obligations. You must achieve a minimum of 95% for these general questions.

Evidence that the MDI theory test has been successfully completed within the last 12 months must be submitted as part of the MDI application.
