Abstract: A coordinate system free definition of complex structure multidimensionalitem response theory MIRT for dichotomously scored items is presented. Thepoint of view taken emphasizes the possibilities and subtleties ofunderstanding MIRT as a multidimensional extension of the ``classical-unidimensional item response theory models. The main theorem of the paper isthat every monotonic MIRT model looks the same; they are all trivial extensionsof univariate item response theory.
