Academic developers play a key role in advancing instructor engagement in the Scholarship of Teaching and Learning (SoTL) at their higher education institutions, but face structural and epistemological isolation. To leverage the knowledge and experience of developers leading SoTL efforts at their respective institutions, a group of academic developers co-created a regional community of practice (CoP) centered on developing evidence-based strategic plans and programming models to advance SoTL at their. We describe the development and outcomes of this regional CoP. Future directions for the use of such a regional CoP model to collaboratively develop cross-institutional offerings are also discussed.
