This paper reports the findings of a study of Multiple Modes of Delivery in Australian universities that was commissioned by Australian Universities Teaching Committee over the period 2001-2004. The project examined and described the various means of educational delivery deployed by Australian universities. It identified the pedagogical, organisational and environmental factors impacting on university decisions to diversify course delivery across more than one location or mode. In this paper the authors report briefly on the first matter--the modes of delivery employed by Australian Universities. The paper focuses on the second issue--factors influencing university decision-making about modes of delivery. (Contains 1 table and 1 figure.)
