Children can learn the German language in kindergarten, at school and in daily life or in intercultural meeting places.
Kindergartens in the state of Niedersachsen have the task of supporting children in language development and, if necessary, to carry out language support measures (https://www.mk.niedersachsen.de/startseite/fruehkindliche_bildung/traeger/sprachfoerderung_vor_einschulung/sprachfoerdermanahmen-vor-der-einschulung-6020.html and

At the school registration in the year before school enrolment, the primary school determines the German language skills. This applies in particular to children who do not attend day care during the last year before school enrolment. Children whose knowledge of German is insufficient to successfully attend the class are required to take special lessons in the year prior to school enrolment to acquire the German language or improve their German language skills. These language support measures take place primarily in a primary school (https://www.mk.niedersachsen.de/startseite/schule/unsere_schulen/allgemein_bildende_schulen/grundschule/vor_einschulung/vorschulische_sprachfoerderung/fit-in-deutsch-6149.html).
All school-age children without sufficient German language skills receive language lessons in language learning classes in the schools. These language learning courses are free. In regular school education, language education and language support are systematically continued as an integrated measure in all schools (https://www.mk.niedersachsen.de/startseite/aktuelles/foerderung_von_fluechtlingskindern_niedersaechsischen_schulen/foerderung-von-fluechtlingskindern-136434.html).
