| Abstract: | Item bias on Forms A and B of the Boehm Test of Basic Concepts was examined for a sample of White and Mexican-American kindergarten children. The method employed to detect biased items, as defined by an items-by-group interaction, was a two-way analysis of variance with followup being conducted with a Bonferroni-type procedure. Bias-in-item difficulty occurred for both groups, which does not conform to the current popular press view that bias is against ethnic minorities and not against the White majority. The finding that on some items the Mexican-American group out-performed the White group indicates the need to examine carefully the question of bias and to reconsider popular conceptualizations of the many issues of bias in educational and psychological testing. |
