Compared the subtest and IQ scores obtained by a sample of 75 learning disabled and retarded children and youth (50 boys, 25 girls) on the WISC-R after a 2-year time interval. Stability coefficients (test-retest) were obtained for the sample. The evidence obtained from the present study indicated that the WISC-R provides stable full-scale IQs.
