The University of Siena has participated in the Erasmus Programme's Key Action 171 for the past eight consecutive years, pursuing long-term goals of strengthening established collaborations with partner universities and promoting the mobility of students and staff to and from these universities. Specifically, within the context of this project and in light of the funding actually granted by the National Agency, the aim was to use the available resources throughout the entire period, which also allowed for adjusting the implementation of activities as the project progressed. All participating Departments actively contributed to the realization of these activities as hoped, and all participants were able to benefit from the expected educational or teaching abroad experience.
