%X the psychometric properties of a figural analogies test are described within the framework of item response theory. thirty-six 2x2 matrix figures were constructed by using location, distortion and number rules. the sample included 499 psychology students from the university of buenos aires, 79% of whom were women. the 3-parameter logistic model was used obtaining a highly satisfactory global fit at 5% (p = .47). only 3 items did not fit the model. it had good overall discriminatory power (a: m = 1.02, sd = .33), a medium level of difficulty (b: m = -.03, sd = .63) and the c level was slightly lower than expected with six possible answers (c: m = .14, sd= .05). the conditions for modelling the test and possible disadvantages of the present study are discussed.
