The present study explored the nature of differences in performance on the 3rd revision of the Stanford-Binet for groups and white preschoolers matched for parental education in two independent experiments. Large mean differences, favoring the white children, were found in both experiments. In addition, significant race × items interactions at level III, in both experiments, and level III-6, in Experiment 2, indicated that the differences in performance between blacks and whites were much larger on some items relative to others. Results were further examined by contrasting items on which black and white performance was not significantly different with items which showed large significant differences in performance.
