Certification

All delegates are assessed throughout the course with multiple choice questions, including diagrams, drawings and photographs. An AEMT Certificate of Assessment is issued to all successful delegates.

Technicians need to attend an Ex Repair Refresher every three years to update them on any changes to the standards. They also have a comprehensive re-assessment of their ability and knowledge before issuing an updated certificate, which forms part of their overall competency record.
