Berber has been recognized as a "national language" by the constitutional amendment of 8 May 2002. Kabyle, the predominant Berber language, is taught and is partially co-official (with a few restrictions) in parts of Kabylie. In February 2016, the Algerian constitution passed a resolution that would make Berber an official language alongside Arabic.
