The publication of this advice and guidance document is timely given that there has been a significant increase in the numbers of learners within clinical imaging and in radiotherapy and oncology departments. In addition, findings from Clinical Education and Training: Capacity and Quality Project Report (CoR 2004) indicated some concern about the relationships between education providers, placement providers and learners. Everyone involved in the education and training of learners, including the learners themselves, have responsibilities to ensure successful outcomes and this document aims to support all those concerned.
