IQ discrepancies between the binet and WISC-R in children with developmental problems

Abstract

Administered the Stanford‐Binet and WISC‐R to 121 children with developmental problems. Twenty‐eight of the children received absolute differences of 12 points or greater between the Binet and WISC‐R FSIQs, with a mean difference of 16.8 and range of 12 to 28 points. While most of these discrepancies were attributable to expected differences between the tests, there were 10 instances of complete incongruence between the Binet and all the WISC‐R IQs. Clinical interpretations of four Binet/WISC‐R discrepancy patterns were discussed.
