The purpose of this chapter is to examine the role that professional development programmes for higher education lecturers and teachers can play in promoting positive, learner-centred assessment practice. Whilst they vary in their coverage, these programmes address a broad range of teaching, learning and other pedagogical issues, and almost all include assessment and good assessment practice as a key component of their curriculum. Therefore, this chapter is used to explain and argue that professional development programmes can and should have a key and distinctive role in developing and sharing innovative assessment practice. The argument is supported by drawing on series of seven principles and ideas, as well as a single-institution case study. Points and arguments are also supported with a range of theory, literature and examples, as well as the experience of the author in working on one programme of this type.
