Sir.—The role of the pediatrician in the evaluation of the child with school problems is clearly outlined by Dr McCormick (Am J Dis Child 131:318, 1977). This is extremely important, as the inclusion of learning disabilities into PL94-142, the Education of All Handicapped Children Act, will, if implemented in its present form, recognize the need for medical evaluation and input only if deemed necessary by the educationally based evaluation team.
I would take exception, however, to his classification of intelligence levels.
The diagnosis of mental retardation by the criteria of the American Association on Mental Deficiency (AAMD) requires both subaverage general intellectual functioning and deficits in adaptive behavior.1 A low IQ is, by itself, insufficient. In addition, his classification is not the accepted one.
The AAMD classification of IQ levels, using the Wechsler Scales, is as follows: mild retardation, full-scale IQ 55 to 69; moderate retardation, full-scale IQ
