In 2019, the President of the European Commission announced the creation of the European Child Guarantee, an initiative that aimed to combat child poverty by making sure that every child who lives in poverty has access to free healthcare, free education, free childcare, decent housing and adequate nutrition. With "Delivering the EU Child Guarantee: Practical lessons for effective interventions," UNICEF Innocenti provides a synthesis of findings of operational research on 15 pilot models of intervention for children and families in Bulgaria, Croatia, Greece and Italy. The goal of the report is to learn from the experiences in these four countries to inform the rollout of the Child Guarantee programme throughout Europe. The study provides lessons learned in three themes: laying the foundations for the Child Guarantee work at the national level; developing interventions at the local level; supporting the Child Guarantee at the EU level.
