No evidence shows that single-sex education works or is better for girls than coeducation.
When elements of a good education are present—such as small classes and schools, equitable teaching practices, and focused academic curriculum—girls and boys succeed.
Some kinds of single-sex programs produce positive results for some students, including a preference for math and science among girls.
Additional research on the effectiveness of single-gender classrooms is necessary, but we all can agree that we need to construct an educational environment that meets the social and intellectual needs of boys and girls.
