The CUNY School of Professional Studies is a small, mostly online school in the largest urban public university system in the US, the City University of New York. Over the past 7 years, with the support of the NYS OER Initiative, our CUNY Central Office of Library Services, and colleagues across our system, our small team has been able to develop a school-wide culture of using OER and Zero-Textbook-Cost materials and of exploring Open Pedagogy approaches for online courses. In this talk, I will share our strategies and suggest how they might be adaptable and scalable for OER advocates in other roles and at other types of institutions.
