The article is based on a national survey in Norway of the linguistic situation of deaf children. Parents, teachers, and children were asked to make judgments on topics related to the children's' language milieu at home and at school by means of detailed questions using two response methods: a language inventory and rating scales. The inventory is more detailed than those in other studies and required all three groups to consider not only the use of the two native languages, Norwegian and Norwegian Sign Language, but other forms combining sign and speech. The data revealed that languages used with the children included both native languages as well as various mixtures depending on context, situation, and the nature and purpose of the communication. The results are considered from the perspective of the amount and quality of language input and intake necessary for language acquisition and literacy. (Contains 1 table and 4 figures.)
