What is the benefit of attending a co-ed school?
expand_more

Co-education creates a real-life comradeship. According to research performed by the American Council for Co-Educational Schooling (ACCES), co-education enhances communication and collaboration among young men and women while building relationships. Learning how to solve problems and work effectively with members of the opposite sex is a fundamental skill that is imperative for success beyond the educational setting.
