Peter B Hamilton, headmaster of the private Haberdashers' Aske's Boys' School and chairman of the Headmasters' and Headmistresses' Conference academic policy committee, said: "A-levels are and will remain the most important examination for young people completing their pre-university education.
"Michael Gove is right to want university input into the much-needed review of A-levels but it would be most unwise to give universities total control.
"Those who teach 16 and 17-year-olds know best what they need, both to expand their knowledge base and develop their study skills, so input from successful sixth-form teachers will be equally important in getting an examination system fit for the 21st century."
