What happens when a peer-assisted learning scheme becomes "business as usual" rather than innovation? The proctoring scheme in undergraduate philosophy programmes at the University of Leeds has been running for over 25 years, making it one of the oldest (and possibly the single oldest) continuously running higher education peer-assisted learning schemes in the country. Over time, the centrality of the scheme in the teaching environment has changed, particularly in the shared understanding of philosophy learning and teaching and in the practical constraints of curriculum and timetable space. Using the insights of teachers, students, and graduates, this report identifies the extent of success for proctoring in fostering philosophical learning and developing academic community, the two major objectives for the scheme. We also identify the conditions for success of peer-assisted learnings schemes, which our results suggest. An unexpected outcome of this project is found in identifying a challenge around "value" resulting from the fee-paying environment in higher education where peer-assisted learning may be (mis)understood as "teaching on the cheap." These findings raise important questions for all higher education peer-assisted learning schemes about how schemes are embedded, sustained, and remain central to the learning environment in a rapidly changing education environment.
