The project aims at developing different materials and guidelines already published and used for national internships in order to create a handbook adapted to transnational internships. This handbook will be disseminated with an European scope in order to prevent unsuccesful mobility experiences, make clear the role of each actor in cross-border internships, facilitating the quality procedures of the whole mobility experience and standarizing them both for old EU and new EU members taking into account common and local needs. The main objective of the project is to ensure the quality of the cross border mobility experience for a wide range of vocational training student regardless of company sector, country, and field of vocational training.
