Mary Bousted, general secretary of the Association of Teachers and Lecturers, said the IoE research confirmed what was always suspected.

"All the research shows single-sex schools are good for girls but bad for boys – both in terms of academic performance and socialisation," she said. "Boys learn better when they are with girls and they actually learn to get on better."
