Studies carried out in Switzerland and all over Europe, have shown that risks of unemployment and marginalisation from the labour market are correlated with a lack of qualification.In particular, young adults who prematurely interrupt their training cycles (“drop out”, early school leavers and etcetera), face serious difficulties to integrate themselves in a stable manner in the labour market.Despite good purposes and active measures undertaken all over Europe to fight early school leaving, the issue is still open and specific efforts should be made in order to promote qualification pathways addressed to young adults. In this sense flexible offers of learning opportunities with personalised training pathways can be a way to facilitate the achievement of a recognised qualification. Furthermore, workplace learning, informal experiences and recovery of basic knowledge, skills and competences should be better integrated in a comprehensive learning setting.Starting from a previous German national project (named EPRO), the Second Chance project developed a comprehensive training model, which is trying to answer the following questions: -How to develop flexible and personalised training, able to facilitate the acquirement of a proper professional qualification, dedicated to people who risk to be left out from the labour market?- How to aid them to approach a professional training opportunity?- What measures should be adopted in order to recuperate the basic competences needed for professional training?
