Children can learn the German language in kindergarten, at school and in daily life or in intercultural meeting places.
Kindergartens in the state of Sachsen have, in order to the education plan for the kindergartens, the task of supporting children in language development and, if necessary, to carry out language support measures (https://www.kita-bildungsserver.de/themen/sprachfoerderung/).
School-age children with a migrant background receive German lessons in preparatory classes or preparatory groups in primary schools and secondary schools. In addition, in Saxony the subject "German as a Second Language" is taught as a regular subject according to a scientifically proven curriculum by trained teachers. These lessons start from class 1 and are the basis for equal participation in regular lessons.
