The Leonardo program da Vinci is one of sectorial programs of the program Education and Training throughout life and a device promoted by the Agency Education Training in France and in Europe. Its access for professionals and populations stemming from the fields of professional sociocultural community development and social intervention remains difficult. Paradoxically, it is still a question in France of convincing people in charge of the structures of sociocultural community development and of youth of the interest which can represent for the apprenticeship and socialization of their employees or the social and occupational insertion of their public training in mobility. From an analysis of the experiences led by the CEMEA, this text approaches the resources, the limits and the perspectives to come from the program Leonardo da Vinci, by underlining how the vocational training in mobility can be formative for the sociocultural community developers.
