Through this Higher Education mobility project, IES Inventor Cosme García initially intended for two Higher Vocational Training students to undertake internships in companies participating in the Erasmus programme. Ultimately, a mobility programme was implemented in the field of Administration and Finance, enabling students to acquire complementary training by undertaking internships in institutions specialising in their field in a European Union country. In this case, the selected student did not meet all the requirements to carry out the mobility as a curricular internship (FCTs) and it was finally carried out as a voluntary internship. This student carried out her mobility in an organisation in Slovenia, where she was able to learn and develop as a person and as a professional. Our intention was to be able to carry out another mobility programme, but the remaining budget was not sufficient. We can therefore conclude that the project has met its qualitative objectives, although not so much its quantitative ones.
