The article focuses on the cooperation between the school, parents and educational day care centres operating in the child protection system in Paris. It takes into account the way children and parents participate in this collaboration. In the range of services offered under the child protection system, day care centres are recognized as innovative due to the cross-sectoral nature of the support offered. The data was collected through two stages of interviews with parents and children. 23 children and young people aged 8 to 16 and 22 families participated in the study. Research interviews were also conducted with interdisciplinary teams and specialists involved in the collaboration. Documents on the situation of all 23 examined children were analysed. The presented study received positive opinions from the Ethics Committee of the Faculty of Psychology and Educational Sciences of Paris Nanterre University. The study was funded by the National Observatory for Child Protection and the four associations participating in the study.
