الملخص EN

This study aims at estimating the properties of ability distribution and item parameters of test to, according to parametric and nonparametric models of item response theory.

It also aims at comparing between : the three-parametric, the four-parametic and Mokken non-parametric models.

To achieve the objective of the study, the data of the educational quality control test of fourth grade in general science, that consisted of 25-multiple -choice items were analyzed.

The sample of the study consisted of (1010) fourth grade students chosen from public, private, schools in Jordan in the school year 2012 / 2013.

The results of the study showed significant differences in the means of the discrimination parameter of the items between the three parametric and the three non-parametric one the results also, showed differences in the distinctive parametric item for the use of the four parametric model compared to the three non-parametric model, in favor of the three parametric model, and between the four parametric and the three non-parametric models, in favor of the three non-parametric model, the three parametric also surpassed the four parametric model.

The results also showed significant differences in the means of the item difficult parameter, between the three non- parametric and the four parametric models, in favor of three non-parametric model, and between the three non-parametric and the three parametric models, In favor of three non-parametric model.

The results, however showed no significant differences in the means of the guessing due to the used model.

The results also showed significant differences in the standard error of ability parameter estimation between the four parametric and the three parametric models, in favor of the four parametric model ; and between the three non-parametric and three parametric models, in favor of the three non-parametric models.
