With regard to your article, 'Superhead' is transforming school (Oxford Mail, May 14), I would like to query the percentage passes of five GCSEs, A-C, that are given.

My understanding at the former Drayton School at Banbury is that 34 per cent of students achieved five or more GCSEs, A-C, in 2006 under the headship of Richard Sutton.

In 2007, under the acting head, this fell to 22 per cent.

If these figures are correct, it makes 'superhead' Ruth Robinson's "outrageous" target of 30 per cent more achievable, one would hope.
