In this chapter, we develop a definition of e-leadership that extends from the business sector to encompass educational contexts. We describe schools as complex ecologies and dynamic organizations that require a change in both traditional forms of leadership and more recent ICT use. We use the RAT (Replace, Amplify, Transform) framework to explain the varying degrees to which ICT has been used in business and education and relate this model to the research in e-leadership. It is through the purposeful, transformational use of ICT and the meaningful development of multiple kinds of knowledge that those in charge of teacher education and growth can use ICT to develop a new kind of teacher leader.
