Education and Adoption Bill

I am interested in what the right hon. Lady has to say about failing academies because, as she will know, the regional schools commissioner is involved in one academy in my constituency that Ofsted judges to be inadequate. Will she define what she means by a “coasting school”? That is important because we tend to think of schools as failing when they perform at a relatively low base, but is it not the case that a school can be coasting if it does not push highly academic pupils as hard as it can so that they achieve the best that they can?
