The Return Counselling Toolkit is a capacity-building instrument aimed at providing a harmonized and coherent approach to return counselling based on key migrant-centred principles. Accompanied by operational tools that can facilitate the work of return counsellors, the toolkit is conceived to address the capacity-building needs of return counsellors, as well as to strengthen the knowledge of other return stakeholders, including national and local authorities and civil society. The toolkit has a global perspective, although it also includes specific content focusing on the Western Balkans. It builds upon, complements, and further consolidates the existing IOM institutional expertise on counselling, as outlined in key resources such as the IOM Reintegration Handbook as well as IOM Handbook on Protection and Assistance for Migrants Vulnerable to Violence, Exploitation and Abuse, and other key IOM publications. The toolkit also contributes to the operationalization of the IOM’s Policy on the Full Spectrum of Return, Readmission, and Reintegration.
