Sturgeon said she wanted to be judged, above all, by the results of her efforts to eradicate the educational ‘attainment gap’ between children in rich and poor areas. Six years ago the attainment gap was 16.9 percentage points. This year it is 17.1 percentage points. Even the current consumers of Scotland’s failing school system will be able to work out that’s an increase, not a reduction. So by her own lights she can be judged a failure. And let’s not forget that, after almost a decade as First Minister, she left Scotland as far away from independence (always her real political priority) as ever.
