So it's a question of trying to remove some of the luck from that equation and say, "Actually, we've got to do a better job of supporting aspiring school leaders so that they can move on to those very important leadership roles better supported." It shouldn't just be pot-luck. You shouldn't just be able to take a great classroom teacher, put them into a principal role without properly supporting them to do that, because, actually, that's the way you lose your brilliant classroom teachers, because they just get overwhelmed and burnt out. This has been a persistent problem since Tomorrow's Schools was introduced. Amazing teachers just get burnt out by the overwhelming demands of being a school principal.
