International schools in some form or another have been around for over a century and much of the research has focussed on what an international school is or what it is intended to do, and the focus on international teachers as a body of professionals remains unclear. In this chapter the author reflects on who these educators are and re-positions the notion of international teacher categories and posits more relevant definitions. The author observes an annual cycle from the point of recruitment, through induction, period of teaching, to when a teacher decides to stay or leave. Through this cycle, following the progress and development of the literature over the past two decades, the author argues how staff ideals have shifted focus, including an understanding of international teaching through the student context, and concludes that newer, globally mobile teachers have transitioned from a culturally bereft group to one of cultural sensitivity with a global outlook, and how Western teachers are being joined by Eastern counterparts, adding to the globalisation of education.
