An extensive literature has explored the influence of the OECD on school education policies globally, while their influence on higher education policies has been underexamined. This article addresses that void by analysing the internationalisation of higher education in Israel and South Korea. We suggest that joining the OECD provided political legitimacy for both countries and that the OECD comparative metrics and guidelines were crucial in generating anxieties about their underperformance in the global market for international students. These metrics served as benchmarks for internationalisation policies and shaped the foci, aims and definitions of success (i.e. parity with OECD averages). The desire to compete spurred cross-national policy referencing and borrowing, initially with little adaptation resulting in a form of 'prefabricated internationalisation'. Over time, the (im)balance between global aspiration and local realities resulted in localisation. We argue that policy isomorphism is overstated, and call for the recognition of complexity in the convergence debate.
