| Abstract | This study examines item bias on Forms L and M of the Peabody Picture Vocabulary Test-Revised (PPVT-R) for 132 Anglo-American and Mexican-American children in grades one through four. Analyses of variance were employed to assess item bias as defined by items x ethnicity interactions. Follow-up analyses were performed using a Bonferroni-type procedure on individual item contrasts. Bias as measured by differences in item difficulty was found for both groups; however, there was no clear pattern to the items that were more difficult for either group. The small number of items that were more difficult for one ethnic group than the other, coupled with the high reliability of performance overall for both groups, suggest that bias in content of the PPVT-R is minimal.
