This handbook is designed as a toolbox for applied and practice-orientated migration and integration research. After a concise introduction to the most important concepts of transdisciplinary and participatory research, key methodological requirements and challenges are presented. At the heart of the book are the individual instruments that encourage collaborative evaluation of integration work and the impact of migration. This practice handbook, which also contains suggestions for reflection on and the dissemination of results, is aimed at academics, policymakers, practitioners in public administration and civil society organisations as well as volunteers.
