The scientific network “Universalist Children’s Services: From Two-Part to Inclusive Social Infrastructure,” funded by the German Research Foundation, comprises 20 researchers. Its purpose is to contribute to the development of a more inclusive design of the public children’s services system. To achieve this objective, the network integrates legal and educational perspectives in its analysis of the current structure of the children’s services system. The network’s starting point is the concept of universalist children’s services, and its aim is to engage in experimental discussions on the potential transformation of the current (exclusive) two-part structure into a predominantly universalist service framework. The ultimate goal is to initiate a foundational and interdisciplinary discourse to identify future research needs in this field.
