Within the framework of the CaixaProinfancia programme, networks have been developed in 18 regions of Spain which promote intersectoral cooperation to combat the social and educational exclusion of children. Their emerging nature and simultaneous development have enabled a comparative study to be made of their organisation, the supporting and inhibiting factors, and the perception of the results. The conclusions stress the importance of leadership which takes into account the principles of transversality and horizontality, as well as properly focusing the socioeducational action and implementing it within a relatively short period of time. Some networks evolve in their approach, going from attending to the participants' needs to more global approaches to socioeducational governance.
