In schools in Rheinland- Pfalz, mother tongue education is an important component in promoting the multilingual competence of pupils. It is an offer for pupils from elementary school to the end of secondary school. The lesson usually covers 3 to 5 hours per week and is provided by native-speaking teachers under state responsibility.
In native language education, pupils with a migration background take up already acquired competences in a family or native language. At admission to school parents can register their child to the mother tongue teaching. Learning groups are also set up across schools, depending on the number of participants.
In Rheinland-Pfalz, depending on the location, mother tongue teaching is currently offered in the following languages: Albanian, Arabic, Bosnian, Chinese, Farsi, Greek, Italian, Croatian, Polish, Portuguese, Russian, Serbian, Spanish, Turkish, Kurdish / Sorani and Hungarian.
