As institutions not founded to "serve" Latina/o students, Hispanic Serving Institutions (HSIs) must actively change their curricula and programs to meet the needs of their diverse population, including Latina/o, low income, and first generation students. Using a case study approach, including interviews and focus groups, this study examined culturally relevant practices at one HSI, including the ethnic studies curriculum and student support programs. Specifically, findings highlight how the Chicana/o Studies department and the Educational Opportunity Program have historically served underrepresented students and the ways in which such programs are embedded within the structures of the institution. This study has implications for HSIs and other institutions enrolling and serving diverse populations.
