The National Coalition of Girls Schools (NCGS) offers these benefits of attending an all-girls school:

• Nearly 100% of girls’ school grads go on to college.
• Three times as many alumnae of single-sex schools plan to become engineers.
• Girls’ school students spend more hours a week doing homework, attending study groups, tutoring others, and working with their teachers than co-ed school students.
• In a single-sex school, a girl can comprehend her value and her capabilities in ways that have nothing to do with how she looks or whom she dates. Not only is she not in a bubble, she’s utterly free to do anything and everything she wants. She can experiment and explore, trying out new things and trying on new identities.
• At a girls’ school, a girl occupies every role.  She has a wealth of avenues for self-exploration and development and a school full of peer role models.
• While girls’ schools may succeed in drawing out the socially underdeveloped, they tend to attract the girl who is a misfit of another kind: one who is bold, socially independent, and smart as can be. She is untroubled by and indeed thrives in a single-sex environment. In her close-knit community, her individuality is nurtured and fed. As a result, a girl becomes more and more comfortable making her own decisions and determining the course of her own life. She becomes accustomed to speaking up and, more importantly, being heard.
