Having more girls in the school could help boost boys' educational performance, according to a recent study. The research investigated how the school environment influenced boys' and girls' educational performance in secondary schools. Studying the reading test scores of more than 2,00,000 15-year-olds from over 8,000 mixed-sex schools around the world, researchers discovered that boys' performance was significantly better in schools where more than 60 per cent of the pupils were girls.
