This paper outlines the methodological issues I faced during my research as a "returning native" in an English secondary school. The empirical research took the form of a three-year case study and used some ethnographic methods, as it comprised interviews carried out over a period of three academic years in the school in which I was once employed as a teacher. I was also given the opportunity to work in the school as a consultant in the lead-up to and during its Office for Standards in Education, Children's Services and Skills (OfSTED) inspection. This enabled me to conduct interviews, observe, interact in informal conversations and participate in the inspection week. In this paper I explore the unique role of the insider-researcher, or returning native. Not only was this a school in which I had previously worked, but actually participating in the inspection added new layers of complex loyalty. (Contains 10 notes.)
