 the return of migrants to their countries of origin and their reintegration into the communities that receive them are natural features of international mobility. Generally, we understand reintegration as a multi-dimensional process enabling individuals to re-establish the economic, social and psychosocial relationships needed to maintain life, livelihood and dignity, and inclusion in civic life. Many returnees may require assistance as they go through this complex process. It requires stakeholders to work closely together. But how to go about it? IOM has developed tools to guide reintegration practitioners. The reintegration handbook provides practical guidance on designing, implementing, monitoring and evaluating reintegration assistance programs. Reintegration can occur in various contexts. The handbook focuses on migrants unable or unwilling to remain in their host countries to return to their countries of origin. IOM has also developed a reintegration training curriculum that offers practical resources and sessions to deliver reintegration training. It consists of a self-paced course, face-to-face and blended training sessions and a facilitator's guide for those delivering the training. A training program on monitoring and evaluating return and reintegration programs including the same elements is also available. With the application of these tools, practitioners can adopt evidence-based approaches in the design, implementation and monitoring of reintegration programs thereby contributing to reintegration sustainability. The EU IOM Knowledge Management Hub has helped to develop reintegration programs that facilitate the sustainability of reintegration processes worldwide. Train a pool of facilitators who, in turn, train new reintegration practitioners in their respective countries. Organize regional workshops, allowing practitioners from different countries to exchange best practices and strengthen their collective knowledge.
