Yale University offers a graduate qualification in Women’s, Gender and Sexuality studies. The program establishes gender and sexuality as fundamental categories of social and cultural analysis and offers critical perspectives upon them as a basis from which to study the diversity of human experience. Gender (the social and historical meanings of the distinction between the sexes) and sexuality (sexual practices, identities, discourses, and institutions) are studied as they intersect with class, race, ethnicity, and nationality. The introduction of these perspectives into all fields of knowledge necessitates new research, criticism of existing research, and the formulation of new paradigms and organizing concepts.
