Although we know a great deal about college choice in nations such as the United States, we know considerably less about how college choice operates in settings lacking well-defined hierarchies between higher education institutions. In the United States, the United Kingdom, and France, students from high socio-economic status backgrounds are over-represented in the Ivy League, Oxbridge, and grandes écoles, respectively. In nations without these hierarchies, how do privileged families distinguish between very similar institutions? Using the example of Canada, notable for its relative institutional flatness, I show that privileged families construct their own hierarchies and tap into established hierarchies in other nations. The data come from an ethnographic study of two elite private high schools in Toronto, Canada.
