Taking on responsibilities associated with a professional role is an important aspect of experiential learning for undergraduate students on work-based placements. However, responsibility is a complex concept that is connected to issues of trust and risk in the placement context. This paper presents students' perspectives that illustrate that being given and taking responsibility can be empowering; conversely, being denied responsibility is disempowering. Through an exploration of the students' experiences, the relationship between responsibility, opportunity, risk and trust is explored. The paper points to a strong indication that the extent to which students are allowed responsibility in the workplace appears to have a fundamental impact on their perceptions of personal efficacy and professional development.
