The awarding of the Nobel Peace Prize to a person who fights for the rights of children should be considered a sign in the right direction: Malala Yousafzai (17) is the youngest competitor ever known. Her courage and commitment show that young people can achieve great things regardless of their origin and age. And it is clear that participation must be linked to the issue of fundamental democratic rights and the education of young people. Young people want to have their say and approach their dissatisfaction in various ways, more or less well received in society. The objectives of the training are to share and reflect on existing practices of youth participation in order to reinforce qualitative practices allowing to overcome the obstacles to participation and to offer tools consistent with the realities and expectations of young people. We therefore wanted, through this training, to pool our experiences, confront our realities and exchange good practices to explore this subject and overcome these prejudices of low interest of young people for the "life of the City". It is a question of understanding, as youth workers, on the one hand, the obstacles that young people encounter to this participation in different contexts, of analyzing the existence of discriminating criteria as regards participation and, on the other hand , to exchange contents and tools allowing to approach with the young people their conception of the roles which they can play in the Company and to deconstruct certain received ideas on the matter, to encourage and facilitate their participation in particular that of young people who are usually distant.
