A small number of children have brains which are so malformed or damaged that they make little response to special methods of education. A survey of the forms of brain abnormality in these cases has been carried out by Crome (1954). The category of children who can properly be classed as ineducable is, however, strictly limited and should, probably, be confined to idiots. Williams (1957) has pointed out that the task carried out in occupation centres for imbeciles is that of “educating the ineducable”, whilst a number of recent studies have shown that imbeciles have much more educational capacity than is generally assumed.
