This paper discusses the issues raised when delivering professional doctorate programmes to students at a distance. It explores the importance in doctoral study of engagement with a research community, what a "community of practice" might mean within the academic context and the problematic nature of working with students already operating within their own professional context and engaging with another community of practice--that of the researcher. It uses the example of a Doctor in Education (EdD) programme to explore the implications of using virtual learning environments to enable students at a distance to participate in the programme. It draws the conclusions that, far from being a new form of delivery, creating opportunities for students to engage with an academic community of practice requires tutors to use tried and tested pedagogical strategies in a new context. In doing so we use Moore's (1993, in Jung, "British Journal of Educational Technology," 32(5), 525-534, 2001) concept of transactional distance to develop a new model of delivery, arguing that whilst dialogue needs to be increased, rather than loosening the structure, it is better achieved by tightening the structure to allow greater adaptability of content through careful moderation by tutors.
