The overall objective of the Policy Lab is to translate subjective children’s views and their understanding of well-being into policies that tend to deal with objective measures and indicators of integration and to develop child-centred migrant integration policy based on adjustability, flexibility and contextuality and migrant children participation. The ambition underlying of the Policy Lab is to develop policy recommendations on the one hand and engaging with the policy-makers as potential adopters, particularly at the level of educational systems, on the other.
