„Migrant children often need additional help to successfully integrate, such as intensive language training or support classes. […] Some 82 % of the surveyed cities’ answers indicate that special classes for migrant pupils in public schools were created. Most of the time, these classes are administered or funded by the national level and they bridge the knowledge and language gap of migrant students until they can join standard classes.“
