About 9,500 Victorian vocational students have had to hand back their certificates after concern about the low quality of education training.

In addition, eight registered training organisations have had their contracts terminated while two more were surrendered after the “findings of non-compliance”.

A recent Senate inquiry found private training organisations and education brokers had deceived students about fees and job outcomes.

The review identified $4.2 million in funding that needed to be recovered.

Many students were signed up by high-pressure sales, cold calls and even door-to-door education brokers.

The high pressure sales are driven by earlier VET FEE-HELP reforms, which made it easier for students to get government financial assistance.

Colleges and brokers receive a commission on the courses they sold, which were often much more expensive than similar courses readily available at TAFEs.

But the lack of regulation on training providers now means nearly 10,000 students have to give up their qualifications, while another 3,000 students’ training is being investigated.

The TAFE sector has been warning governments that the new market-driven system would benefit dodgy private training courses.

“We indicated if you don't pull it in we'd have a major blow-out in costs and within a few years time you'll have employers screaming at you that you are training people and giving them qualifications that aren't worth the paper they're written on,” former executive director of the Victorian TAFE Association David Williams told the ABC

“And that's what's happened.”

Steve Herbert, the Victorian Minister for Training and Skills, blamed the previous government.
