As many as 300,000 11-year-olds will find their national curriculum tests cancelled this morning.
The estimate of the amount of disruption caused by a boycott of the tests - in maths and English - increased yesterday. Christine Blower, general secretary of the National Union of Teachers, said that the number of schools backing the boycott ranged from 30 per cent to 75 per cent from local authority to local authority. Overall, about half of the 17,000 schools due to sit the tests are set to abandon them.
