Furthermore, ENS has strong parternships for research at Master's and Doctorate levels, sending its students to universities around the world to complete their tuition. It also shares thesis habilitation with universities abroad, meaning that somes theses can be written with support from both the ENS and one of its partner institutions. It is also customary for students in the literary and linguistic subjects to go to teach for one year in universities abroad with the position of junior fellows. These exchange and cooperation programs link ENS with universities such as the University of Beijing in China, Freie Universität Berlin in Germany, the universities of Cambridge, Edinburgh and Oxford in the United Kingdom, Trinity College in Dublin, McGill University in Montréal, and the universities at Berkeley, Columbia, Cornell, Harvard, Princeton, Stanford, and Yale in the United States.
