In order to be admitted to EDGE, students must be admitted to the doctoral program of one of the participating institutions. Each institution selects among its top students those to be to accepted for EDGE. The selection process is based on academic excellence. After a student has been selected to participate in EDGE and to go to a particular partner institution, the details of his or her exchange will be discussed with the host institution at least three months before the arrival of the exchange student. It is essential that students try to get financial assistance through other means (e.g. national institutions or foundations of their home countries). This has to be initiated well in advance because some application deadlines expire as early as one year before the exchange starts.
