A multi-professional research team comprising practitioners, academics, service-users and students has undertaken a major research project on pre and post-registration students engaged in Social Work, Midwifery and Emergency Care (Nursing and Paramedicine) professional degrees. This book explores students' perceptions of the tools and methods used to assess their practice and the impact these processes have had on their learning and professionalism during their journey through the programme. A four-year longitudinal study comprising annual interviews with 14 students has enabled their developing understanding and changing views to emerge, rather than just gaining a snapshot as in previous literature.
