The integration of women into the U.S. Naval Academy is analyzed. Areas of concern identified before the arrival of women in the class of 1980 were fraternization, acceptance, physical conditioning, berthing, leading and counseling females, publicity, athletic outlets, extra-curricular involvement, summer cruises, weight and diet requirements, and roommates. These areas are looked at with reference to other controlling issues: policy, admissions, attrition, academic and military performance, physical standards performance, conduct and authority, leadership performance, dating, and general living conditions. It was found that women have successfully adapted to the rigors of Academy life and have shown equivalent performance on a majority of outcome measures. In the initial class, which entered in 1976, attrition was high, but the rate has declined. Subsequent classes have experienced more integration and less assimilation, with more reciprocal change. Policy continues as a basis of inequity, and must change for women to be taken seriously in the Academy, and low female enrollment ensures inadequate representation in the authority structure.
