In universities, an important part of intellectual capital is the research- development-transfer capital (R&D&T capital), due to the process of creation of scientific and technical knowledge and its transfer to the social environment. The aim of this paper is to identify the types of knowledge that act as drivers of R&D&T capital in a public university. To this end, first key knowledge types in reference to the strategic objectives of the university are identified, through both examination of documents concerned with the objectives and plans of the university and meetings with leading officers of it. Second, the activities involved in the process have been analysed through in-depth personal interviews with a group of heads of research teams at the university. The results of the interviews have received both qualitative and statistical analyses. Subsequently, a definitive list of key types of knowledge as drivers of university R&D&T capital is also presented.
