Thanks for the replies,
I had a feeling they might be the case.
In the end I did end up submitting an application, as I would be no worse off.
Due to the different RTO's way of doing the cert 2 or pre apprenticeship means that you can only go to them to complete your cert 4.
I'm no expert in the training/assessing field. But I would imaging there would be a governing body, quality or check & balance in place to prevent this type of act from occurring.
