Who educates teacher educators? How are teacher educators educated and prepared for their roles and tasks? This article uses a review of a two-year full-time Diploma in Teacher Education (DTE) for teacher educators in Uganda to engage with these questions. The article begins with a presentation of the Ugandan teacher education context and a literature review, focusing mainly on teacher educator knowledge, preparation, roles and tasks. It then presents the review process and discusses the main findings that emerged, exploring their implications for the education of teacher educators in Uganda and internationally. The main implications concern the critical role of teacher education pedagogy, context, teacher educator knowledge, tasks and roles, reflective practice, practitioner research, and the background, capacities and education of the educator of teacher educators.
