The work of teacher educators is complex and multifaceted and requires knowledge of pedagogy and practice in both schools and teacher education institutions. This complexity, combined with calls for teacher educators to work in close partnership with schools, sees some in teacher education working in hybrid roles and across the boundaries of schools and universities. Drawing on a self-study conducted over a one-year return to teaching, I explore my return "home" to teach in a secondary school and I examine the continuing impact of this experience on my practice as a teacher educator. Using the concept of tensions as a conceptual framework to analyse the data I explore three tensions in this article: (1) teacher as technician versus teacher as pedagogue; (2) challenging versus being responsive to other's views of learning; and (3) teacher versus teacher educator identity. I explore how a return to teaching in school and the tensions I experienced enabled me to develop my practice and understandings as a teacher educator. I argue that rich professional learning can result from using self-study to examine teacher educator practice, particularly for teacher educators working in hybrid roles and partnership contexts.
