"The decision to reject a training organisation's registration is not one we take lightly but the interests of students and the integrity of training standards across the VET sector have to be upheld," said ASQA chief commissioner Chris Robinson.
"The institutions have the right to have ASQA's decision reviewed which may delay or change the decision," Robinson added.
