REFORME PLUS is a 36-month ERASMUS+ project that brought together 7 vocational training organisations from 6 European countries belonging to the transnational REFORME network and supported by the social partners of the construction sector. All the project partners are leaders of national or regional networks and bring together a total of more than 300 initial and continuing training centers in the construction sector.The REFORME PLUS project partnership is composed of :- CCCA-BTP (FR- leader) : http://www.ccca-btp.fr/- BZB (DE) : www.bzb.de- CENFIC (PT) : http://www.cenfic.pt/- Center IFAPME Liège Huy Waremme (BE) : http://www.centrelhw.ifapme.be/- FLC (ES) : http://madrid.fundacionlaboral.org/- FLC ASTURIAS (ES) : http://www.flc.es/- FORMEDIL (IT) : http://www.formedil.it/Our organizations are facing the same challenges: the constant need to promote apprenticeship training (or alternation depending on the country) in the building and public works sector, to work on the attractiveness of its branches, its trades and the associated careers. To do this, they must constantly improve the quality of the training provided and of training courses in general. In addition, we have all been involved for several years in international development, through mobility and cooperation projects. This allows us to pursue many objectives, in particular:- the internationalization of our young people's careers (and their skills, employability, openness, etc.);- the professionalization of our teams and the development of their skills, especially in teaching;- pedagogical innovation in our establishments, adaptation of our training to the needs of the job market.This non-exhaustive list allows us to measure the benefits of cooperation between our institutions. REFORME PLUS has allowed us to give a framework to the development of these collaborations, to strengthen our network and its activities and to increase the internationalization of our teams by involving them in the activities and mobilities of the project. The exchanges of practices, experiences and know-how and the learning activities have mainly focused on the following three themes:- Improving the image and attractiveness of apprenticeship in the construction sector by focusing on successful careers in the sector.- Increasing the quality of training: pooling and exchanging good practices for European cooperation in order to guarantee the quality of training and training paths delivered by REFORME partners.- Developing new types of mobility: in particular with regard to tutors in companies; and long-term mobility (at least 2 months).These three objectives could only be achieved by involving the main actors and vectors of change present in the training centers and in the companies: training managers, trainers and mobility coaches and company tutors/mentors. This is why the REFORME PLUS project planned five learning activities addressed to these participants for a total of 45 mobilities and at least as many local participants. Due to the impossibility to travel during the health crisis and especially during the second half of the project, 1 learning activity could be held face-to-face (Mobility of the 2 Spanish partners in France); 1 other was organized at a distance (Virtual mobility of the French partner in Belgium). They gave rise to 21 physical and virtual mobilities and mobilized a minimum of 27 local participants.These activities were composed of workshops and information and exchange sessions on the three themes mentioned above, aiming at developing and promoting the internationalization of the participating institutions.In addition, 4 transnational meetings were held; 3 face-to-face and 1 remote during the covid period. They gathered a total of 50 participants and made it possible to work on the three stated themes, including each time the intervention of an external expert on a given theme.REFORME PLUS has thus contributed to strengthening the links and exchanges between the partners of the Reforme network. The exchange of practices and the perspective generated by the interventions and workshops have fuelled the partners' reflections on these different subjects. The participants in the two learning activities greatly appreciated sharing and confronting their needs and issues, which are often common across borders, but in different contexts.
