All trainers and assessors delivering VET programs are required to hold a qualification known as the Certificate IV in Training and Assessment (TAA40104) or the more current TAE40110, or demonstrate equivalent competency. They are also required to have relevant vocational competencies, at least to the level being delivered or assessed. All TAFE institutes and private RTOs are required to maintain compliance with a set of national standards called the Australian Quality Training Framework (AQTF), and this compliance is monitored by regular internal and external audits.
