Ok I have been just looking on the website and it has this:

Will I receive the same accreditation from Cengage Education that I would get through other education providers like TAFE or OTEN?
Answer. Yes. Cengage Education is a Registered Training Organisation under the Australian Training Framework. We are registered with the NSW Vocational Education and Training Accreditation Board (VETAB), which means that our accredited courses provide you with exactly the same qualification you would receive if you studied the course at TAFE or OTEN.
