Two strategies for assessing item bias are discussed: methods comparing item difficulties unconditional on ability and methods comparing probabilities of response conditional on ability. Results suggest that the iterative logit method is an improvement on the noniterative one and is efficient in detecting biased and unbiased items. (Author/DWH)

The purpose of this research was to recommend an item bias procedure when the number of minority examinees is too small to use preferred three-parameter item response theory (IRT) methods. The chi-square, Angoff delta-plot, and pseudo-IRT indices were compared with both real and simulated data. (Author/DWH)

Two matched forms of a 50 item grammar test were developed. Twenty items designed to be humorous were included in one form. Inclusion of humorous items did not affect grammar scores on matched humorous/nonhumorous items, nor on commmon post-treatment items. Inclusion did not affect results of anxiety measures. (Author/DWH)
