It depends on what they are trying to achieve.
If they are separating checking from training, then that could be a good thing.
I dont work for Jetstar but if they are trying to turn it into a big T organisation by separating checking from training then that might not be a bad thing.
There are some people who are excellent trainers, others that are excellent checkers, some (but not all) that are both.
In my opinion training and checking should be separate, checking should be a QA process to verify that the training is doing the right thing...
Standing by for incoming!
