The purpose of the study was to research good practices at three school levels--preschool, compulsory school, and secondary school--that contribute to the social and academic success of immigrant children and students. The project integrates four subthemes and main research areas, including children/students, teachers, leaders, and policy. We used purposive sampling methods to identify successful schools for the study, primarily by the means of external expert groups. We then identified through school leaders successful children/students within each of the schools, whom we engaged in semi-structured interviews. This study is a part of the Nordic research project "Learning spaces for inclusion and social justice: Success stories from immigrant students and school communities in four Nordic countries." The aim of this case is to introduce and discuss methodological and conceptual challenges encountered, a number of which confronted the research team, including choosing successful schools and research with immigrants, children, and youth related to positions of power and social difference.
