In this book we try to demonstrate the effectiveness of the strategies and methodologies of socio-cultural animation and mediation in the context of re-education and social reintegration of minors at risk. This case study allowed us, on the one hand, to analyse the extent to which the educators at the institution in question are aware of the use and importance of these methodologies (role-playing, group dynamics, non-interfering methods, audiovisual methods) within the institution's re-education programme. On the other hand, it aims to see how representative the minors interned at the Training Center are of their own social reintegration. This work, which aims to provide contributions and possible solutions to common problems in today's societies (of a familial, economic and social nature, especially experienced during adolescence and with an impact on juvenile delinquency), is aimed at social educators, sociologists, cultural animators, mediators, teachers and other professionals linked to the social sciences.
