The COTRASO (La CO-formation en TRAvail SOcial: enjeux et pratiques) project aims to encourage and assist universities, schools and social work training centres in developing participatory training modules. These innovative training courses are based on the involvement of people directly involved in socio-educational support and enable them to share their empirical knowledge in the service of more ethical, empathetic and humane social and educational work that is fully faithful to the principles of social justice.
