School heads criticise new league tables
New league tables are being published for England's secondary schools, the first to include a new measure, the English Baccalaureate.
It will show how many children achieve good GCSE passes in what the government considers to be core subjects
But Brian Lightman, general secretary of the Association of School and College Leaders said the problem with the changes was that they were "retrospective".
He said it is unfair to rank schools on this now, because the measure was not in place when GCSEs were taken last summer.
