Harvard College has a unique service model that is rooted in a history of student-led/staff-supported service. This model of students creating relationships with community partners to provide critical services started in 1904, and has resulted in additional transitional housing, out-of-school time programs, adult and senior programming for Boston and Cambridge. Phillips Brooks House Association (PBHA), a student-run independent non-profit has been called the "best course of Harvard" by students because of the transformational impact on their own civic identity and understanding of social change. In 2021, we surveyed over a thousand alumni to understand why this unique model works and how do we incorporate those lessons to all of our programming.
