This study examined the reliability of the Mantel‐Haenszel indexes across different samples of test takers as well as across sample sizes and investigated whether these indexes are robust to item context effects. Mathematics data from the Second International Mathematics Study (SIMS; 1985) for U.S. eighth‐grade students were analyzed. The results suggest that the MH D‐DIF is robust to item context effects. However, larger sample sizes than those used in this investigation (N = 141‐167 for the focal group) may be necessary to obtain stable estimates from the Mantel‐Haenszel procedure.
