"The project “Multidimensional training of adult volunteers to foster migrants' integration” (MAV) was strongly committed to achieve ""take-up and effective outreach"" of the targeted migrants: the conceptual orientation of the project was based on integration to be promoted through involvement of migrant volunteers acting as mentors of other migrants. ""Guidance and motivation strategies"" were conceived as relevant objetives in order to achieve integration in a smooth but immediately effective manner, to stimulate the migrant volunteers to become propagators of the awareness, soft skills and comptences lernt within their wider migrants' communities. The method choosen strategically combined integrated learning package traditional approaches with innovative motivation and guidance tools, to ensure the migrants volunteers' interest, hence the propagation of the benefits of the MAV adult learning via these migrant volunteers to other migrants. This enables the project to offer direct peer-to-peer mentoring. In this way, MAV contributed to enhance the achievement of migrants integration and produced products for sustainable use in mainstream-service provision.The main approach of MAV was to focuse on volunteers who serve as ""mentors"" for other migrants (including refugees, third country national and non native in general) in order to better guide them into participation in their host societies, into the European labor market, help them to identify and improve their skills and competences and to continue to build upon competences they might have had in their countries of origin.MAV created a learning tool kit for adult volunteers (especially adult migrants in volunteering) to better self-train and qualify volunteers to manage for ""their migrants"" the transition process between ""arriving as migrants"" up to being integrated. Training is available on the MAV online platform. In particular, the project was implemented in seven project countries (Germany, Italy, Romania, Greece, United Kingdom, Cyprus and Turkey) by seven expert entities sharing different but complementary focus areas, which carried out learning interventions for volunteers to promote their engagement in becoming mentors and facilitators of other migrants as further users of the ""lesson lernt"". Within its conceptual orientation, MAV integrated relevant considerations in the field in a comprehensive and multidimensional approach, and achieve the following results:(1) MAV created 1) The MAV guide for trainers, 2) The MAV adult learners' toolkit, 3) The MAV adult training course and 4) The MAV Communication Toolkit. The guide for trainers, the adult trainings courses and the communication toolkit are available in all partner languages (EN, DE, EL, IT, RO, TR), whereas the adult learners toolkit is available in EN and DE,(2) During the project appr. 540 key players in the project countries were involved in the project implementation, in MAV conferences and appr. 280 stakeholders ettendes multiplier events,(3) 70 experts and professionals working with volunteering as groups of experts were consulted,(4) 140 migrants were involved in piloting of outcomes and courses,(5) appr. 4.000 users have been visiting and using the MAV online platform(6) institutions and organisation in England, Germany, Italy, Greece and Romania will continue to use MAV products in their mainstream service provisions for migrants and refugees."
