The Equation Of Intelligence Tests Developed Using The Real Degree In The Classical Theory

The research aims to current equation intelligence tests developed the Two Philip Carter (2008) to The test was applied to a sample of (560) students, and Fadel current research between the three methods of the equation in the classical theory, namely, (averages, linear, Almienja ) and five of the methods of the equation in the theory of features inherent in such form binary parameter (2PL) and three-parameter (3PL), the researcher used the statistical programs of the following, respectively, in data processing and analysis of the (Excel), (SPSS17), (Winsteps ), (Bilog-MG3), (Xcalibre, 4.1.6.0), (ST), (CPIE), (PIE); and the calculation methods of the equation and compared.  and reached was the following conclusions:
1. Fit tests with the four-level students to mental Baghdad five-governmental organizations, and the homogeneity of its vocabulary, and mild degrees of frequency distribution of the respondents.

2. The four tests be equally significantly, it has been possible from being the preparation of conversion tables on the first test grades to the grades equation on the three other tests, according to each method of the equation
