26 children with hearing loss of 71-120dB were trained for more than three years by uni-sensory method by hearing, and were able to enter the ordinary elementary school. They were tested in VIQ, Japanese achievement, reading ability after nine years of age, and the relation between the grade of hearing loss, PIQ, starting age of training, training period in preschool years and the present language ability were investigated.
The results were as follows;
(1) 18 children (70%) with above 90 in VIQ at school age kept the same level. 8 children (30%) less than 89 in VIQ did not develop and some showed lower level.
(2) 18 children (70%) with more than 90 in VIQ after nine years of age got a good mark in Japanese achievement test and reading ability test, but 8 children (30%) with less than 89 in VIQ got a bad mark.
(3) Language ability at school age closely related to the mark of VIQ after nine years of age. Efficient preschool training was indispensable in order to keep the high mark of VIQ after nine years of age.
(4) The grade of hearing loss, PIQ, the starting age of training, training terms, added parents' direction, were concerned the development of VIQ at school age. Profound hearing loss and low mark of PIQ, training start after two years and seven months old, preschool training terms for shorter than four years, poor direction of parents inclined to get the low mark of VIQ.
