"Impact" is a notion that is not very well understood in research. Within Australian higher education, it has been bandied about within such frameworks as the "Research Quality Framework" ("RQF") and Excellence in Research for Australia (ERA). Vocational education and training (VET) research is not immune from these movements, and increasingly, VET researchers need also to be keeping a weather eye on the impact of their research. As a contribution to our understanding of impact and how it might be applied in VET research, this paper explores the notion. Following a review of relevant sources on impact, it uses as its case study evidence on the work of the Australian VET research consortium, "Supporting VET providers in building capability for the future", and interprets available data within the framework of one of three potential models proposed in Australasia for the measurement of VET research impact.
