The study examined some statistics of children with disabilities, relevant research and education, and welfare policies undertaken for the last three decades. The changed perceptions regarding children with disabilities have led education and legislation to great improvement. As a result, the number of children who are registered as having disabilities has been increased. Also, children who received any benefits of education and welfare have been consistently risen. The noticeable features of the existing studies are summarized as follows : An increase in number, a variety of the contents, specification of the topics, and a close connection to the basic studies. In spite of the progression and improvement observed in the areas of education and welfare policy making, more practical approaches are needed in order to reflect various needs of children with disabilities and their families.
