The Erasmus+ project at the European University of Madrid was requested within the framework of a new Vice-Rector's Office, which proposed different strategies from those of previous calls. The main objective was to intensify the institution's internationalization at all levels, ensuring efficient use of available funds and seeking the best academic results. The goal was to achieve a tangible return on each international activity, benefiting not only the direct participants but also the entire university community. All of this had to be carried out in line with the horizontal European priorities, already initiated in previous projects, and within a changing global context whose impact on international mobility was uncertain. Within this framework, it was proposed to extend mobility to all participant groups and foster interconnection between departments and faculties, in order to achieve better quantitative and qualitative results in terms of internationalization. Likewise, it was considered essential to promote "internationalization at home" in an inclusive manner, through new agreements, activities, and events, taking into account both the high volume of international students studying at our institution and incoming mobility, which transforms the diversity of classrooms and determines outgoing mobility itself. It was also highlighted that the differences between international academic programs and the cultural specificities of the participants directly influenced internationalization models, making the coordinated work of all units of the Vice-Rectorate for Students and University Life—Library, Internships, Employability and Entrepreneurship, Academic Orientation, Diversity and Equality, and International Relations—essential to adapt to these dynamics. The ideal project also reflected the emergence of new forms of international mobility, shorter and with a distinctly European character, as opposed to traditional intercontinental internationalization. In this regard, priorities were set as: promoting sustainable transportation, including profiles with fewer opportunities, and digitalizing processes as a pillar of efficiency, with special attention to initiatives such as Erasmus Without Papers and the European Student Card. Under this premise, the entire institution had to support the Erasmus+ project, led by the International Relations Office. Additionally, as part of a global enterprise, the University had to follow internal guidelines that aligned both with local needs—such as those emanating from Villaviciosa City Council—and with European policies channeled through the Erasmus+ National Agency. In this context, the importance of responding to social change toward a more international society, governed by tolerance and integration, was emphasized, as well as leveraging intercampus social networks and participation in international events, which not only strengthen institutional visibility but also allow for learning from best practices at other Spanish and European universities. The purposal also incorporated an organizational learning component. Based on the results of previous reports and recommendations from SEPIE audits, improvements were implemented, such as simultaneous project management and strengthening transparency and efficiency in all processes: from program promotion and dissemination to the completion of the internship, including payments and document processing. Special attention was paid to promoting internship mobility in Europe and employee mobility, areas in which growth opportunities were identified. Furthermore, strengthening the experience of incoming students was considered a priority. In line with the conclusions of previous projects, the development of a specific plan was proposed to guarantee real benefits for this profile, which required close collaboration between the various administrative units and the Faculties. In conclusion, the work of the entire University should revolve around internationalization as a strategic axis, learning from past mistakes, investing efforts efficiently, and aligning actions with European development goals. Disseminating knowledge about exchange opportunities, as well as promoting internationality inside and outside the classroom, were key lines of action in the pursuit of significant results for all participants.
