WISC-R AND INTERNAL EVIDENCE OF TEST BIAS WITH MINORITY-GROUPS

Judgment of test bias can be made on the basis of a number of criteria. This study examines the evidence on the cultural bias of the WISC-R for Anglo-American, Black, and Mexican-American children. The performance of 1,050 children aged 5-11 yrs on the internal criteria of reliability and a number of order-of-item-difficulty measures was assessed. Minority group Ss responded to the test in the same general way as did Anglo-American Ss, and there was no clear pattern to the items on the test that were more difficult for minority Ss. Thus, the WISC-R appears to be nonbiased for minority group children. Explanations other than specific item content should be sought for the observed discrepancy between majority group and minority group IQ test performance.
