Abstract	This brief technical note describes how to construct item vector plots for dichotomously scored items fitting the multidimensional three-parameter logistic model (M3PLM). As multidimensional item response theory (MIRT) shows promise of being a very useful framework in the test development life cycle, graphical tools that facilitate understanding of the interaction of examinees and items are becoming more important. These informative visual aids include item response surfaces, equiprobability contour plots, and item vector plots. This note is focused on item vector plots used to visually describe a large number of multidimensional items in one graph. (Contains 1 table and 1 figure.) (ERIC).
