Assessment processes are fine and are important as regards gauging future success but to be expected to pay for one at a commercial school where you're, presumably, considering being a paying customer is a bit cheeky.
Independent organisations such as GAPAN also offer aptitude testing for a fee. Fine - it's a useful service they offer and I'm not considering giving them 60k soon afterwards.
The selection costs
should be absorbed by the FTO as a cost of doing business. OAT are a business, they will aim to make a profit.
A bit too idealistic perhaps but certainly fair. To get into university you have your qualifications/experience and no doubt one or more interviews. Job done. No cash exchanging hands - except maybe travel and accommodation - certainly nothing for the actual process. If there is a
requirement (as at OAT) to go through selection, then it should be subsidised or paid for by the school. This, of course, applies to all FTOs, not just OAT.
Crikey this industry is expensive!!!
