In order to deliver life-long learning for teachers, practitioner-based enquiry learning is being promoted by teacher education institutions on the basis that this form of learning gives teachers the ability to understand factors affecting learning within their own classrooms by systematic investigations of issues and the construction of an evidence-base on which decisions which improve learning can be taken. In turn this enhances teacher professionalism. This article presents a study of how practitioner-based enquiry was embedded in an initial teacher education programme; the reasons for this; and the purposes of the strategy, which raised the one-year postgraduate qualification to masters-level. It looks at the reasons for the change; the nature of the change, which included educating teachers intending to teach in primary schools together with those intending to teach in secondary; the introduction of practitioner-based enquiry; some early student reaction; and the structural, cultural and learning issues which have emerged.
