Institutions of higher education (HE), public and private, are moving through a crisis period of tapped-out states, funding cuts, tuition increases and layoffs. It makes good sense to rise to meet these new realities with new ways of doing things, and the places that succeed will be the ones that do. A holistic approach is necessary whereby excellence in teaching and learning as well as research should be the ultimate aim. Among the various ways to achieve this, is the promotion of communities of practices (CoPs) among the academics. Therefore, CoPs are to be seen as an "extension" of any programme to achieve excellence, because as it has been shown it is the sharing of the tacit knowledge that makes the difference in any organisation in its pursuit for a competitive advantage. An HE institution should be considered to be at a greater advantage than any other non-academic organisation since each staff member is a knowledge worker whose mission is to transmit, create and incorporate new knowledge to the existing knowledge. This paper looks at the possible reasons preventing academics from participating in a CoP. It will be shown that CoPs can play a very important role in a university set-up.
