Transnational higher education (TNHE) development is not an entirely new international activity in the education services sector. The nature and scale of the global expansion of contemporary TNHE developments are, however, changing substantially. An understanding of this growth is currently largely lacking because of a dearth of comprehensive statistics. The scale of the latter TNHE developments has been particularly hard to identify and has until now been largely based on guesstimates. This article is an attempt at filling this gap. Through a triangulation methodology of available secondary data, this article is a very first attempt at providing a stock take of the current level of activity in TNHE worldwide.
