This week's revelation that independent schools in Oxfordshire could drop A-Levels in favour of a new examination being developed by a board connected to Cambridge University has caught us by surprise.

Understandably, it has brought condemnation from state schools. It could see universities favouring pupils from the independent sector if they feel a new exam is a better guide to a potential student's ability.

The Government has also announced a review of A-Levels. Latest developments make it all the more important it gets this right.
