The term “good practice” refers to an innovative and creative solution crafted to enhance the living conditions and, consequently, the well-being of individuals and communities. However, this concept is profoundly contextual. A project, process, or outcome can be deemed “good” or “innovative” only concerning a particular context and its capacity to meet a specific need. Hence, adopting and adapting a good practice originating from elsewhere to a new context must be approached on a case-by-case basis. This article outlines the methodology utilized to analyse the good practices gathered at the European level within the Horizon 2020 IMMERSE research project. In this study, we have combined the primary indicators of migrant and refugee children integration with the conventional criteria for identifying a good practice (such as efficacy, efficiency, and transferability) to identify exemplary practices. Ultimately, the article offers an empirical evaluation to underscore and scrutinize some of the most pertinent initiatives identified, intending to propose a series of policy recommendations geared towards enhancing well-being and fostering successful pathways for the integration of migrant and refugee children.
