In Sweden, there has previously been no normalised test material for the evaluation of language development in individual hearing-impaired children and for the assessment of various methods of auditory habilitation. A test consisting of nine subtests was therefore assembled and developed for, and subsedquently applied to, hearing-impaired children in the age range 4-6 years. The inclusion criteria were a pure tone average of 80dBHL or less and oral language (Swedish) as the first language. 211 hearing-impaired children and 87 normal hearing control children were tested. The results show that 1) children with hearing impairment - also unilateral - have a delayed language development; 2) the delay is greater in children with larger losses and decreases with increasing age; 3) six-year -olds with hearing loss greater than 60 dB have not reached the level of the control group. In only 8% was there a delay between parent suspicion and final assessment of hearing impairment. No difference between right sided or left sided deafness with respect to language development was observed. Furthermore, a reference materal, applicable during clinical assessment, was established for the most common types of hearing impairment.
