„Some countries initially place immigrant students in specific preparatory reception classes within regular education institutions before entering the mainstream classroom. These classes often focus on language learning and are used in about half of European OECD countries as well as in Japan. The idea is to teach late arrivals a minimum level of the language of instruction and to help them adapt to their new school environment before they transit to the mainstream classroom.“
