Single-sex education can have enormous benefits for female students. Numerous studies have shown that women who attend single-sex schools tend to have stronger self-confidence, better study habits and more ambitious career goals than women who attend co-educational schools. Girls who graduate from single-sex schools are three times more likely to become engineers than those who attend co-educational schools. The reason is that all-girls schools encourage women to enter fields traditionally dominated by men, such as science, technology and engineering. In co-educational schools, girls are often expected to succeed only in humanities or the arts. Research has also shown that in co-educational settings, teachers are more likely to praise and give in-depth responses to a boy’s comments in class. In contrast, they might only respond to a girl’s comments with a nod. They are also more likely to encourage boys to work through problems on their own, while they tend to step in and help girls who struggle with a problem. In an all-girls setting, girls are more likely to speak up frequently and make significant contributions to class than in a co-educational setting. Girls studying in a single-sex setting also earn higher scores on their College Board and Advanced Placement Exams than girls who study in co-educational settings. All-girls schools tend to be smaller than co-educational schools, which means teachers will be able to tailor the materials to girl students’ personal learning styles and interests.
