This research aimed to identify the differential item function for everyday creative behavior inventory (ECBI) using ordinal logistic regression model, item response theory models and its impact on the differential test function by multiple group confirmatory factor analysis. The sample consisted of 1820 student of New Valley University (483 male students, 1337 female students), by using (R) program. The following results were reached: 1) everyday creative behavior inventory (ECBI) has good psychometric properties, but it needs to be developed. 2) some items of the everyday creative behavior inventory has differential function favoring of males, and some of item favoring of females. 3) the impact of differential item function on the differential everyday creative behavior inventory function as a whole, the results interpreted in the light of the various factors that can lead to differential item function and the differences of the scientific basis for the item response theory models.
