This study aimed at using the Item Response theory in constructing a Criterion-Referenced Test in Mathematics according to the Two- Parameters Logistic Model. To achieve this aim, the researcher prepared a pool Dichotomous items consisted from (50) items and a pool of polytomous items consisted of (10) items. The items were constructed to measure the conceptual understanding, procedural knowledge, and problem solving. The study sample consisted of (502) students and all of them responded to all items. Results of the study indicated that (IRT) assumptions were achieved in the study data. Also, the results showed all dichotomous item achieved a goodness of fit according to the 2-parameters model, and all Polytomous items showed goodness of fit according to the Graded response Model. In light of the results of the study, the researcher recommended search a set of recommendations
