Possible bias in the differential predictive validity of the Kaufman Assessment Battery (K‐ABC) was investigated with 76 Anglo and 90 Mexican American fifth‐ and sixth‐grade boys and girls. All children were English‐speaking and from similar socioeconomic backgrounds. The criterion variable was the Comprehensive Tests of Basic Skills (CTBS; Language, Reading, Mathematics, and Total Scores). Several statistical techniques were used to investigate test bias (examination of predictive validity coefficients; two methods of examining homogeneity of slopes of the regression lines). The results showed considerable evidence of bias in differential predictive validity, indicating that the global cognitive score of the K‐ABC (the Mental Processing Composite) was less effective in predicting CTBS scores for the Mexican American group than for the Anglo group.
