Throughout the project's implementation, the objectives included: a) achieving the University's goals for modernization, internationalization, and extroversion; b) addressing the needs and goals of each participant, whether student or staff; c) ensuring compliance and harmonization with the program's regulations for quality implementation (in adherence to the binding ECHE principles) and proper funding management (by the Special Account for Research Funds-ELKE); d) implementation of activities in alignment with the 2021-27 horizontal priorities. The project aimed for both quantitative and qualitative goals, such as retaining and enhancing the quality and quantitatively increasing student mobility, particularly outgoing students, for both studies and traineeships, as well as teaching staff for training and teaching. Additionally, the project aimed to increase the number of incoming staff through the organization of the 2nd (10/2022) and 3rd (10/2023) International Week of DUTH.
