How to realize the global development of children with intellectual disability is a complicated social issue. When a child has intellectual disability or is on the verge of intellectual disability, the environment the child is in and the humanistic support the child obtains play a vital role in achieving the global development. Given the intrinsic factors cannot be changed, and then the extrinsic interventions subsequently become the only means for children with intellectual disability to achieve personal development. However, conventional education cannot meet the special needs of children with intellectual disabilities, so training special supporting teachers has become the best choice to achieve this goal.
