„Just as fluency in the language spoken in the host community is important for adults because it ensures their economic and social integration, language fluency among school-aged children ensures that they are able to make the most of the learning opportunities offered by schools. […] Language fluency enables children with an immigrant background to participate actively in the social life of their school, and develop a sense of belonging at their school community and beyond.“
