The head of your department decides whether funding from the Study Travel Fund is granted on the basis of the faculty's guidelines for the granting of funds and an individual assessment of the application.
You and your supervisor are responsible for raising funds for the desired study trips. The Study Travel Fund is one of several possible funding sources. Other sources could be foundations. In some cases, your supervisor will cover the expenses from external grants.
In case you are not able to raise necessary funding for the chosen and academically approved change of study environment or course, you and your supervisor must find an alternate study trip.
Funding from the Study Travel Fund must always be applied for prior to the paying any expenses. If you apply for funding after having paid for expenses, you cannot expect to have the costs covered by the Study Travel Fund.
