Undergraduate Diversity Institutes in Philosophy.
This list is maintained by the American Philosophical Association, the institutes operate independently from each other but their goal is to encourage and support undergraduates from underrepresented groups in philosophy. Different institutes have different eligibility criteria, for example PIKSI Boston says that “women, African Americans, Chicano/as and Latino/as, Native Americans, Asian Americans, Pacific Islanders, LGBTQA persons, economically disadvantaged communities, and people with disabilities are urged to apply.” Some of the institutes are focused on a particular topic or area of philosophy, while others are more general. The summer institutes often pay some or all expenses to attend and sometimes provide an additional stipend, deadlines are throughout February or March.
