Most schools in Kuwait would consider an average of 85 and above as normal I.Q. Both mainstream schools and schools for children with Learning Difficulties expect such averages. An I.Q. less than 85 would usually be unacceptable and the child will then have to be placed in a school for children with Special Needs.
