„Across Europe, teaching the language of schooling is organised in several different ways: in separate preparatory classes; in additional classes alongside mainstream classes; through language support in mainstream classes; or a combination of these. Effective integration of migrant students starts with an initial reception period where students’ language skills are mapped, and the right decisions are made according to what kind of instruction students will receive (which class and learning path they will be placed in with what kind of support measures). If students are admitted to preparatory classes (a frequent practice in about half of European countries), it is important to restrict it to a certain time period and combine it with extra support so that students can move to mainstream classes as soon as possible.“
