One issue universities face is the need to demonstrate excellence in postgraduate research supervision at the individual, faculty and university level. While poor supervision might become obvious over time, with grievances, withdrawals and poor completion times and rates, this paper focuses specifically on identifying and demonstrating supervisory excellence. Currently, the amount and range of evidence used to support claims of supervisory excellence tends to be limited, leaving supervisors, faculties and institutions in a position where demonstrating excellence remains difficult. This paper proposes two inter-dependent ideas which, considered together, help to redress this problem. The first is a 'map' for the collection and use of evidence of supervisory excellence. The second is a 'template' for a 'supervisory excellence report'. The 'map' details the organisational elements, uses of data, and data types which can be considered. The 'report' explains one simple and potent way to organise and present these data for multiple purposes. Together they constitute a much-needed framework for promoting and recognising excellence in the supervision of research students.
