2004: Iceland, Legal Recognition of Icelandic Sign Language
Icelandic Sign Language was recognised by law in education in 2004:
Sign language is of basic importance for the development of language, personality and thinking of deaf children. For the deaf, sign language is the most important source of knowledge and their route to participation in Icelandic culture and the culture of the deaf. Sign language is of great importance for all school work and for the pupils' life and work.
