Surely this is the same as the Chinese "logic"? Collateral damage is inevitable, but I can't see it working the way you suggested.

For instance, you essentially said they'd lose 2 decent teachers for every 50 expunged deechers. To my mind, the 2 will leave rather than pay hundreds for doc verification and the 50 will just go and work for unscrupulous employees who will forge their docs for them. Surely this is likely to have a reverse effect on the desired outcome?

For me personally, it would mean degree verification from the UK and then police clearance verification from Australia. The cost would certainly not be "negligible", and to be honest, if the school didn't agree to pay then I'd be off to distant climes.

The system they have put in place may be well intended, but it's certainly ill thought out.
