Abstract
Experimental matrices items were constructed to isolate the effect of option rotation and reflection on item difficulty. Results for 91 firs t to fifth graders showed no significant difference in difficulty for the two test forms and neither rotation nor reflection predicted item difficulty. The strongest predictor of item difficulty was number of t ask dimensions.
