Experience shows that good practice to support Roma people in Europe is usually transferable to the context of migration. This is why this study is relevant in the migrant education context, too. To move school desegregation from the realm of law and policy to real-world practice, an immediate and sustained action is needed. To contribute to the advancement of a comprehensive desegregation agenda, this briefing takes stock of the state of the school segregation of Roma, the initial successes, and the remaining challenges. The briefing does not purport to provide a detailed overview of the issue, but rather aims to help national and local policy-makers, civil society, intergovernmental institutions, and donors set priorities and benchmarks in this area for the next five years.
