The project MEYC! « Move and expand your competencies! » aims at enabling 380 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 organizations (Aquitaine, Poitou-Charentes, Nord-Pas-de-Calais, and Rhône-Alpes – the latter piloting the project) and involving 23 European hosting partner organizations, 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 allowed staff (trainers, administrative staff and managers) to develop new skills in pedagogy and European project management, as well as capabilities to work in a multicultural team. The missions included internships and job-shadowing programs in the socio-educational field, but also training assignments within partner organizations. The experience gained through mobility has enabled 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 inclusion and mental health, youth leaders, artists, cultural mediators…). The long-term objective of this project was to enable the beneficiaries to better understand the dynamics and opportunities related to the European integration so as to develop transnational projects and transmit European values to the public they work with. The impact on youth workers is ensuring a multiplier effect on local territories in fostering the creation 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 has proposed their staff a supportive and pedagogical high-quality framework throughout their mobility. The missions were co-designed with hosting partner organizations and the learners so as to plainly meet their personal and professional learning needs. The experience gained during the mobility has been recognized through the evolution of work assignments and the CEMEA participation in official mobility networks. For the participating organizations volunteer staff, the mobility had a positive impact on their employability. This experimental and innovative project has been implemented from July 2014 to June 2016. It reachs its initial goals and led to further cooperation and international projects.
