The KA131 Erasmus project is part of the internationalisation strategy of the CEU San Pablo University. This project has contributed to increase the number of SMS, SMP, STA and STT mobilities thanks to the signing of new Erasmus mobility agreements or the extension of mobility places with universities with which the exchange already existed. The project aims to offer international mobility to all students of the university, regardless of the degree they are studying. The project has contributed to the internationalisation of the University's teaching, administration and services staff thanks to the physical and blended mobilities that have been carried out. In addition, the project has contributed to the implementation of internal internationalisation actions in order to provide a better service to incoming students, teachers and staff, such as providing support to the university in translations into English, French and Chinese of the website and translation into English of the students' intranet, as well as the establishment of bilingual signage on campus.
