A revised version of Berko’s test of morphology was presented to 30 educable mentally retarded public school children, six each from the Mental Age (MA) groups 6, 7, 8, 9, and 10. Samples of free speech were also elicited from these children. The features tested were compared to the same features in the free speech to see if the test could predict the occurrence or the nonoccurrence of errors in the free speech. Correlational analysis suggested that this was not the case. The conclusion was drawn that the paradigm itself, whether it used nonsense syllables or real words as eliciting stimuli, was not useful in testing development of bound morphemes in educable mentally retarded children.
