In just a decade, the international university rankings have become dominant measures of institutional performance for policy-makers worldwide. Bolstered by the façade of scientific neutrality, these classification systems have reinforced the hegemonic model of higher education--that of the elite, Anglo-Saxon research university--on a global scale. The process is a manifestation of what Bourdieu and Wacquant have termed US "cultural imperialism." However, the rankings paradigm is facing growing criticism and resistance, particularly in regions such as Latin America, where the systems are seen as forcing institutions into a costly and high-stakes "academic arms race" at the expense of more pressing development priorities. That position, expressed at the recent UNESCO conferences in Buenos Aires, Paris, and Mexico City, shows the degree to which the rankings have become a fundamental element in the contest for cultural hegemony, waged through the prism of higher education.
