The fact that children are increasingly cared for out-of-home in the daytime is having an impact on the growing institutionalisation of the early phases of childhood. Since the implementation of the Youth Law in 2016, developing and promoting the quality of non-formal education in the early childhood sector in Luxembourg has been one of the government’s priorities. A framework was introduced to set quality standards in order to harmonise childcare and educational practices and to ensure that education is inclusive and accessible for all. This chapter outlines the development of the non-formal education sector and highlights the mechanisms that have been put in place to develop quality. The national reference framework for instance, describes the fundamental educational objectives and the implementation of the plurilingual education programme. It also implies that the external follow-up is carried out by regional agents whose aim is to assess the written guidelines of the services and to provide long-term support for the progress of educational quality within these services.
