Global Literacy Engagement, a collaboration between the School of Education at Buffalo State College and its school and community partners, has grown in new and exciting ways since its inception in 2010. With an overarching mission to promote literacy and global awareness, Global Literacy Engagement has served as a unique platform to bring together all Professional Development Schools (PDS) stakeholders: teacher candidates, faculty, children, families, teachers, and school and community partners. The goal of this article is to explain how Global Literacy Engagement has embraced a boundary-spanning role to include new PDS sites, locally and internationally, as well as in digital spaces, to meet changing needs. Specifically, in this article the authors describe the origins of the program, its development and expansion, and future plans that hold promise to move in new and important directions while building upon existing PDS structures and frameworks (National Association for Professional Development Schools, 2021).
