Teacher education is in a state of change. There is a new focus on professional competence, including the competence for further development and learning, conceived of as workplace learning. Teacher shortages put pressure on the development of alternative routes to teaching. The arrival of prospective teachers with experience and qualifications in other areas than education requires adaptive programs, with a greater emphasis on professional learning in school. It is argued that promoting professional workplace learning asks for a conceptual clarification, based on new theory of learning and concepts of professionalism. A definition of professional learning is proposed. Some examples of new practice in teacher education are discussed.
