This article presents co-supervision as an effective and efficient model for field education of social work students. In our current climate of scarce resources and with a changing workforce that is increasingly feminised and part-time, this model provides a framework for efficient resource allocation by sharing the responsibility of field education among more than one social work supervisor. We will describe a model of co-supervision that we have developed over a period of 6 years. We will be using the findings from our own exploratory study for this model along with practice-based reflection to support our proposal that co-supervision is an innovative and beneficial model for field work education of social work students.
