This chapter provides a description of five models for professional development (PD) for online instruction and analyzes each model according to domains of effective online instruction (i.e., faculty stance, student self-regulation, faculty support, authentic practice, engagement, community development, and cognitive demand). Additionally, a decision model is provided for K-12 and university administrators, teacher educators, and policymakers to guide strategic decision making in the determination of a model for PD best suited to the needs and resources of their institution.
