Chapter 5 of DETYA's volume "The Impact of Educational Research" (Selby-Smith 2000) begins with an examination of the peculiarity of decision making in the VET sector, followed by an examination of the idiosyncratic consequences for the function of research in the sector. Having established the distinctiveness of VET in relation to these two key factors (decision making and research), the chapter then proceeds to explore the linkages between them. The study on which the chapter is founded identified a complex research culture, in which overt forms of impact are difficult to detect, yet where, it is concluded, research nonetheless plays its part. The research which is likely to impact most heavily is that which is conducted around the practical issues with which VET must deal, preferably with a heavy on-site component, and which is carried out by researchers who are prepared to engage most fruitfully with the VET culture, ideally with a long lead time and maximum follow-up to the actual research phase. Chapter 5 contributes to the overall Impact volume in a variety of ways. First, it offers an insight into the enigmatic nature of educational research in general, and especially as it relates to the VET sector. Second, it makes it clear that educational sectors like VET are likely to be affected by research only when its application to their practical needs is clear and it is carried out by people who are committed to working with their realities. Third, there are broader lessons to be taken from the chapter, especially for university researchers who are imputed by the chapter to be among the least likely to effect research that impacts on practical policy and decision making. While unrelated to the main body of "The Impact of Educational Research" project, Chapter 5 contributes to the overall work through exposing the real world of research impact in what is very likely the least understood of the educational sectors.
