For 30, read 20; for failing, read "schools most in need of transformation". Recent education history is littered with attempts to target such schools, with little lasting impact.

While we have been here before - almost - we have not had a sustained national drive behind such measures before. If this latest initiative genuinely frees schools to do what they think best for their own pupils, backed by imaginative thinking on such factors as the length of the school day and how to attract teachers, it might stand a better chance than its predecessors.
