Online learning is now a common practice in higher education. Because of the continued online enrollment growth, higher educational institutions must prepare faculty throughout their teaching career for learning theory, technical expertise, and pedagogical shifts for teaching in the online environment. This study presents best practices for professional development for faculty teaching online. In this study, the Delphi Method was used to gain consensus from a panel of experts on the essentiality of professional development items to help faculty prepare for teaching in the online environment. After four survey rounds to develop consensus, best practices were identified consisting of essential professional development and institutional/organizational strategies for supporting faculty teaching online. These results are significant for planning new or improving existing faculty development programs that enhance teaching and learning in the online classroom.
