Agroup of headteachers and educationalists who carried out a government-commissioned study on the testing of English primary school pupils noted how divisive the issue was. “Every proposal which enjoys any significant support from some respondents can prompt a negative reaction from others,” it said.

My recent column on the subject prompted a debate on the letters page over whether correct grammar was the key to human contentment. One reader said that without proper grammar “happiness is impossible”.
