The purpose of the study is to identify the patterns of change in higher education institutions. It examines the contexts of the changing quality assurance mechanisms used by the different types of higher education institutions in England, Japan, and New York State between 2001 and 2007. The paper argues that there were no clear patterns of institutional change in terms of speed, intensity, extensiveness, momentum, trajectory, and consequence between centralized and decentralized institutions and public and private institutions. The study suggests three points for explanation why institutional types do not shape certain patterns of institutional change. The first point is that institutional change heavily relies on agents' interactions. The second point is that the ideas of centralized or decentralized and private or public per se are becoming ambiguous in the market or market-like systems. The third point is that the relationship between the central authorities and the institutions is far more significant than the types of institutions in the formation of particular patterns of institutional change.
