The Institut d’ Estudis Aranesi is an academic institution that has the aim of establishing and updating the aranese regulation, and promoting its research and study. It was created in 2002 and depends on the General Council of Aran, which approved its recognition as a linguistic authority of the Aranese language in the Aran Valley in 2008. And it was recognized in 2010 by the Occitan Law as the Aranese of the Aran Valley. In January 2014, the Catalan government adopted a law that allowed to expand this function over all the Catalan territory, where the Aranese is the official language together with Catalan and Spanish, according to the Statute of Autonomy of Catalonia of 2006. It exercises regulatory authority over public administrations and organisms that depend, private and state schools and state-owned media.
