OSCA is a student-owned and student-operated non-profit corporation that provides at-cost housing and dining services to around 400 students at Oberlin College—approximately fifteen percent of the student body. As an organization, OSCA is entirely separate from Oberlin College, but all OSCA member-owners are Oberlin College students.
Each member of OSCA contributes a certain number of hours of work to their respective co-op each week. Members are in charge of almost every task, including food purchasing, cooking, cleaning, coordinating work charts, enforcing food safety, sitting on the Board of Representatives, and more. Together, 5 co-ops make up the umbrella organization of OSCA, and each individual OSCA co-op is responsible for its own day-to-day operations. All-OSCA staff members and employees of OSCA oversee general operations. Through the All-OSCA structure, all 5 co-ops are able to function as a united organization.
OSCA also has a sister organization, the OSCA Foundation, which provides scholarships to students and community members.
