(ABC News) The TAFE SA chief executive will be replaced and an independent review done after a damning audit led to 14 substandard training courses being suspended. Australian Education Union official Howard Spreadbury said the affected courses ranged from aged care training to plumbing and the entire technical and further education system in SA was a mess.

"I am deeply concerned that we need to do something very different to lift TAFE's standards and also to restore public confidence. "That means change at the top." The audit was done by a single commissioner of the Australian Skills Quality Authority and means TAFE now cannot enrol students in 14 of the 16 courses which were reviewed. Opposition education spokesman John Gardner said the State Government was to blame for the mess. "To find out that hundreds of students, nearly 1,000 students, are going to be affected, their courses losing accreditation — this is a disgrace," he said. "Labor has butchered TAFE's reputation here in SA." Mr Spreadbury said the union believed its members
