The government has a dedicated service to help integrate children culturally and linguistically.
For those moving from a foreign curriculum to the Luxembourgish system, whether the child is newly-arrived or going through the process of moving into the local system after spending some years in an international school, Luxembourg’s Ministry of the Education has ‘welcome classes’ to help smooth the process.
Changing systems is also possible vice versa, for those who feel an international or European curriculum would better suit their future plans or for children who are not language-oriented and struggle to keep up with the local system’s linguistic demands. Sources
