NMS iICT also promotes an exchange period during the two years of Master's studies, between the NMS iICT affiliates. For example, NMS iICT students in KTH should consider an exchange period of half a year or a full year in ÅAU or DTU to see more of Scandinavia than just Stockholm. A student in such an exchange period receives some economical support from the NMS iICT.
Application round for NMS iICT internal exchange will take place in February – March. More information will be available on this page then.
