THE council’s new strategy was launched as the Prime Minister laid down a fresh challenge to “coasting” schools.

David Cameron, above, yesterday announced that new league tables will show more data to parents than ever before.

He said too many schools were “content to muddle through”, criticising schools “where respectable results and a decent reputation mask a failure to meet potential”.

He said: “This is the hidden crisis in our schools – in prosperous shires and market towns, just as much as the inner cities.”

In September, the Witney MP triggered angry reactions from Oxfordshire headteachers by accusing schools in the county of “coasting along”.

He said that more than four out of five state schools in Oxfordshire and affluent Surrey were doing worse than some of the best academies in deprived parts of inner London.

Under Government plans, performance data from the National Pupil Database will allow people to trace the progress of anonymous individual pupils.

He added: “It is vital to shine a spotlight on secret failure.”
