One of the most influential advisers to the education secretary Michael Gove has argued in a 250-page paper that "real talent" is rare among the nation's teachers.
While some children will always be blessed by a brilliant teacher, by definition that is not a scaleable solution to our problems: real talent is rare and mediocrity is ubiquitous.
In the controversial paper, he also criticises what he describes as 'third-rate higher education institutions".
In many third-rate higher education institutions there is a large amount of 'social science' work in economics, anthropology, sociology, literary theory and so on of questionable value both from an intellectual perspective and from the perspective of students, jobs prospects.
