Comparison of scores on WISC-III and WISC--R of urban learning disabled students

Wechsler Intelligence Scale for Children-III IQs and Wechsler Intelligence Scale for Children--Revised IQs of 16 preadolescents who were learning disabled, urban students (14 black) receiving special education services were compared. Analyses indicated lower mean WISC-III IQs, correlations of .57, .74, and .72 between scores on Full, Verbal, and Performance Scales, respectively, and significant correlations of .44 to .80 between respective sets of subtests. Exceptions were Information (.34), Similarities (.30), and Picture Arrangement (.15). These results suggest that the WISC-III may compare favorably with the WISC--R, if replicated with a substantial group.
