ABSTRACT
A MONG the unsuccessful cases included in the Study Sample, we found several in which the fact that the child was back-ward or 'dull' seemed to have contributed to his failure in a foster home. But there were also examples of children of very limited intelligence who had achieved very satisfactory adjustment in their new families. It was soon apparent that if there is a relationship between intellectual dullness and foster home failure it is not a simple one, and that we should try to identify the special problems of adjustment within the family to which a backward child may be susceptible.
