The researcher carried out the translation of the test instructions from English into Arabic because the paragraphs are forms, so he does not need to verify the validity of the translation because it crosses culture.

And discrimination according to the two measurement theories and it was found that the value of the correlation coefficient for the parameter of difficulty according to the two measurement theories (0.907) and the value of the correlation for the teacher of discrimination according to the two measurement theories (0.813), and all the correlation coefficients are positive and statistically significant at the level of significance (0.05).

Some conclusions, recommendations and suggestions.
