The Commonwealth of Pennsylvania officially recognizes American Sign Language (ASL). In December 2004, the Pennsylvania State Legislature made American Sign Language a Foreign/World Language.
According to the PA Department of Education, "American Sign Language (ASL) is identified as a world language in the Public School Code. American Sign Language is a complete and autonomous human language with its own unique grammar and frequently used as a form of visual-spatial communication by the hearing-impaired communities."
