Abstract: The relationship between skeletal age and intellectual development of children was siudied in 342 6--11 years old children. The findings showed that the IQs inchildren with askeletal lagwere less than those without such a lag, and that skeletal age was related to mental age. The result suggests that skeletal age, as an index of maturity, may be closely relatedto the intellectual developmnent of children.
