The purpose of the present study was to investigate the utilization of WISC-R scores as a basis for placement and continuation of services for mental retardates in special education classes throughout their school careers. A comparison of the WISC-R Verbal, Performance, and Full Scale IQs with the WAIS-R counterparts and a statistical analysis was conducted. Regular education students were also tested to determine if the two scales were equal.
The WAIS-R was found to yield higher Verbal and Full Scale IQ scores, but comparable Performance IQ scores. These results suggest that the differences between the two instruments for children of subnormal intelligence are educationally and statistically significant, presenting the possibility of differential classification based on the intelligence test used. Future research should be conducted to determine the full impact of this difference on vocational success and adjustment of the affected group, and in subjects of above-normal Intellectual functioning.
