This chapter describes a quality assurance system of collaborative sharing across multiple institutions in Australia and explores, through participant reflections, how such practice can help promote staff confidence and improve facilitation of capstone tasks in the tertiary setting resulting in benefits that derive from a multi-institution approach. A project team consisting of peers from similar disciplines across several institutions in Australia worked together on the project funded by the Australian Office of Learning and Teaching (OLT). Their work verified student attainment standards in the revised national Higher Education Standards Framework (Threshold Standards) (2015) using capstone tasks in coursework at their given institutions. The External Referencing of Standards (ERoS) project was a collaboration between four universities each located in different States: University of Wollongong in New South Wales, Royal Melbourne Institute of Technology (RMIT) in Victoria, Queensland University of Technology (QUT) in Queensland and Curtin University in Western Australia. This chapter describes the ERoS project, the objectives, and outputs so that other institutions can adapt and employ similar models to ensure quality assessment in their capstone tasks and beyond.
