Over the last decade, there has been a steady increase in online learning enrollments. The proportion of college students taking at least one online course is at an all-time high and 66% of higher education institutions indicate that online learning is critical to their long-term strategy (Allen & Seaman, 2014). Universities are increasingly relying on adjunct faculty to meet this need; as such, it is important for institutions to understand the unique motivations, characteristics and needs of online adjunct faculty to better support teaching effectiveness. A survey of 603 adjunct faculty teaching online courses provides an overview of characteristics of modern online adjunct faculty and highlights institutional adaptations necessary to accommodate a changing faculty body.
