This study examines the incidence of differential item functioning (DIF) on three subtests of the iowa tests of basic skills. Test scores for 2,867 alaskan students categorized as native alaskan or white were available at two point in time : fourth and sixth grade or sixth and eight grade. Analysis classified according to one of three language proficiency categories : limited english, bilingual, or english proficient. Although a consistent decrease in effect - size change over time was observed in the comparison between bilinguals and english proficient students, the incidence of DIF tended to be sporadic in terms of which group was favored. Recognizing the inseparable link between language and cultural / ethnic background, an additional DIF analysis comparing whites to native alaskans pf equal english proficiency was conducted to enhance understanding of the language comparison. Effect - size differences, favoring whites, were much larger than those observed in the language comparisons.
