According to the information provided in the third periodical report, the linguistic zoning determined by the 1983 Law on the Use and Teaching of Valencian, into Valencian and Castilian-speaking areas (based on historical criteria) only refers to the field of education. According to the same law, Valencian is a co-official language in the whole territory of Valencia, and in practice local authorities choose their language of preference in line with this zoning (either monolingual Castilian or Valencian, or bilingual). All citizens have the right to use Valencian before authorities in the entire territory of Valencia.
