المستخلص: The present study aimed mainly at revealing the precision of some estimates of CTT and IRT methods as a basis for demonstrating differential item functions when using different ordered test forms. Data were collected from a total of 901 randomly selected students from 16 out of 25 primary schools using Thus, it was found that by comparing the methods of the CTT theory and the methods of IRT theory, there is a marked increase in the number of items that have the differential item function advantage and that the methods of IRT theory were more accurate, precision, and consistent With the differential item function advantage of items. The results of the analysis of the current study, data show that EH is the more advantage method followed by the random method R, while no positive or advantage of HE method showed, and the test and reordering of its items and confirm its basic psychometric characteristics such as (validity, reliability and unbias) and giving to the examinees of a high degree of importance and necessity that it will be used in the making of decisions of those examined.
