Article 251(1) of the 1973 Constitution of Pakistan, titled "National language", specifies: "The National language of Pakistan is Urdu, and arrangements shall be made for its being used for official and other purposes within fifteen years from the commencing day." Although Urdu has been declared an official language, so far all government documents, legislation, legal orders, and other official records are written in Pakistani English. Most higher education instruction is in English. The National Language Authority is an organization established to make arrangements to promote Urdu since 1979.
