This paper presents an overview of approaches and proposals to improve the integration of migrant children in schools in Spain and it is linked to the European research project Migrant Children and Communities in a Transforming Europe (MiCREATE). It focuses on a part of the research in which stakeholders were interviewed. Based on the needs of migrant children and practices already implemented in Spain, experts from different fields problematised and proposed improvements in current policies and practices in education. The main conclusions indicate that a more holistic and transversal approach to the inclusion of migrants is needed, as well as better coordination between institutions in different contexts and areas of action. This implies rethinking inclusive practices and involving children's families and taking their environment into consideration, as well as supporting educational practices that foster a sense of belonging among migrant children and their families in schools, the community, and society. Finally, the paper highlights the importance of gathering data from stakeholders in different fields of expertise and areas of action in order to obtain a more complex and insightful overview of the phenomenon under study.
