This paper discusses experiences of a student-ambassador network within one UK-based Centre for Excellence in Teaching and Learning, problematising key issues in relation to transience in staff-student partnerships in HE, and highlighting the importance of the educational developer in facilitating institutionwide partnership models. Theoretical explorations are supported by data gathered throughout the Network's operation, including student evaluations following the first year of operation, and a final "impact study" conducted with staff and students. The article develops the notion of a "collective conscience" 2 model of student engagement, which supports all students via a variety of activities, incorporating short, mid-rage and long-term goals, and enabling a range of collaborative and individual opportunities for success.
