Good or promising practices in return governance are thus defined here as context-specific policies, programmes, interventions, or projects that have demonstrably improved outcomes for migrants and stakeholders—such as better rights protection, procedural fairness, reintegration prospects or access to legal pathways—while aligning with agreed normative standards. These practices may be temporary or permanent in nature, but must be sufficiently documented to allow learning, adaptation and potential upscaling in other settings. Policy transfer and upscaling are therefore treated as key analytical dimensions in assessing the promise of identified practices.
