The aim of this chapter is to show how the use of a specific participative research method allows us to highlight how some public programmes aiming at tackling ‘dropout’ amongst young people can miss their target and objectives. To unpack this research perspective, we have adapted the sociological intervention to analyse young people’s experience of these programmes. Lightened, reframed and renamed as the CCAPPA (for Contradictory, Collective and Participative Policy Analysis), this method has been used as a powerful tool to enable young people to be reflexive with regards to their own situation. CCAPPA, with its participative dimension giving a full place to the young people in the research process, has allowed us to shed light on questions that a traditional methodology will not have been able to capture.
