RenaSup is a non-profit organization, directly associated with the General Secretary of the French Catholic Education. RenaSup is a network of 515 schools from middle school to higher education. Every project carried by RenaSup aims at promoting quality standard, professional insertion and social success. RenaSup is part of a project called ‘Success for all’ and initiated by the Catholic Education. This project aims at developing measures to promote equal opportunities. Although this dimension of success for all is fundamental to acquire social cohesion, the feeling of inequality often generates the desaggregation of the social body, communitarianism and sometimes extremism that aims at rejecting others.
