In this chapter, we focus on the links between learning and processes of informal participation. We do this by closely examining some of the activities of Welcome, an association created by a small group of volunteers in 2016 in Rennes with the aim of delivering French classes to people in exile. This particular case study was conducted within the framework of the Partispace project as an example of informal participation organised by and addressed to young people. Welcome is an interesting case for exploring learning and processes of informal participation, for several reasons: it is a young association, created in 2016; its organisation and activities can be characterised as informal as it operates without any public funding; it is dedicated to people in exile and thus tends to respond to the lack of mobilisation of public authorities towards this population. The aim of this chapter is to look at the effects of learning processes developed inside the association by focusing on participation and engagement pathways of both young volunteers and people in exile. The research question broached here is: To what extent do non-formal learning activities of a volunteer association lead to participation and engagement careers among young volunteers and people in exile, and consequently, to what extent do these activities influence individual life trajectories in the local public space?
