The Braeview story may well be unusual: 10 unsatisfactory scores are unprecedented in an HMI report. But the speed of the school's decline also seems unprecedented. From being given a clean bill of health only three years ago, it has now been placed in intensive care. Either HMI got it badly wrong the first time round, or something dramatic indeed has happened in the school.
There will no doubt be plenty of ministerial satisfaction that this precisely illustrates the need for new legislative powers. Why did the authority and the school have to wait for an inspection before taking action?
But the fact is that the school and the authority are taking action - without any ministerial powers, as has happened before. Weak leadership can transform the fortunes of any organisation. The Braeview community must now fervently hope that the opposite is also true.
