The prevalence of children with suspected learning disabilities (LD) was investigated. One thousand and eight-hundred-eighty-nine pupils at ordinary elementary classes were evaluated by class teachers. We defined suspected LD as a. condition with normal IQ (not less than 70) and low PRS score (not more than 65). Eighteen children (12 boys, 5 girls, and 1 with sex unknown) were considered as suspected LD with this criterion. The prevalence of suspected LD at elementary schools was 0.95%, the lowest figure as compared to those in previous reports. The suspected LD children were studied for the LD type and school grade. Verbal LD was not found, non-verbal LD was found in 6 children, and mixed type in 11. In the study of their school grades, the third grade suspected LD children were the largest. There was a significant decrease in number at higher school grades.
