This thread makes some very interesting reading. Sounds like Oz ATC could do with lots of new people and need help retaining the ones they do have.
From an outside point of view there seems to be a very high failure rate which makes me wonder if a) they are using the right recruiting techniques to start with and b) they are trying to rush people through the course due to the shortage and therefore not giving the people on the course a fair go.
To me it does not make sense to only have 2 people out of a class of 12 pass, throw the other 10 away and start on the next batch. Would they not be better off giving those 10 who failed more training to get them up to speed? Or am i reading this wrong and they do do this already?
