But what we've seen in the past, again—and I look back and I don't put any particular Government to blame for this, because it's happened over economic cycles of about 30 years—is that we've kind of had a boom or bust programme for teacher supply. So we've either had too many teachers, and they've complained they haven't been able to get jobs, or we've had too few. So one of the things we'll have to be very careful about is that we don't over-correct—so we don't train too many teachers and we get to that point where we end up with people saying "I've just spent four years training for a job and there's no jobs for me.", but actually make sure that we're training enough teachers. So I think the better modelling and data that the ministry has been able to achieve will certainly help us to make sure that we're getting that teacher supply situation right.
