The project “Beyond the borders, expand your competencies” (BECOME) aims at enabling 358 youth workers working with progressive education methods to experience a positive professional mobility in Europe. This project, collectively promoted by a consortium of 4 CEMEA training organisations (Aquitaine, Basse-Normandie, Nord-Pas-de-Calais, and Rhône-Alpes) and involving 19 European hosting partner organisations, has been designed to reach a double strategic objective: internationalize training activities related to education and youth work; meet youth workers’ learning needs in this field. This mobility will allow staff (trainers, administrative staff and managers) to reinforce their competencies in their field of action, to develop new skills in pedagogy and European project management, as well as capabilities to work in a multicultural team.The missions will include job-shadowing programs in the socio-educational field, but also training assignments within partner organisations. The experiences gained through mobility will enable CEMEA staff to propose new European and international trainings to CEMEA trainees and local partners ( socio-educational trainers, youth workers, social workers working in the field of mental health actors, teachers, artists, cultural mediator, etc.). The long term objective of BECOME project is to enable the beneficiaries to better understand the opportunities and dynamics related to the European integration so as to develop transnational projects and transmit European values to the public they work with. The impact on European youth workers will ensure a multiplier effect on local territories in fostering the development of intercultural project and the development of an awareness to a European culture amongst young people. Based on their extensive experience in supporting the mobility of learners, CEMEA will propose their staff a supportive and pedagogical high-quality framework throughout their mobility. The missions will be co-designed with hosting partner organisations and the learners so as to plainly meet their personal and professional learning needs.The experience gained during the mobility will be recognized through the evolution of work assignments and recognition tools such as Europass or VET certification. For the participating organisations volunteer staff, the mobility will also have a positive impact on their employability.The BECOME project follows on from the consortium « Move and expand your competencies ! » (VET Staff mobility 2014-2016 coordinated by the CEMEA Rhône-Alpes). MEYC! enabled CEMEA Rhône-Alpes to acquire numerous competencies in European project management and its continuous assessment contributed to the development of BECOME project covering June 2016 to May 2018. BECOME is also meant to be standardized so as to be transferred from a European country to another..
