Abstract EN

This study aimed to reveal the effect of the gravimetric methods and the degree of cut-off on the psychometric properties, and to achieve the objectives of the study, an achievement test was built in the mathematics course for the sixth grade of primary school.

) students, and the sample consisted of (521) students, chosen by simple random sampling method, and grades were estimated through four weighted methods, namely : the normal method (raw score), the delta-score method, the alpha-score method, and the binary model (post-expectation method).

arithmetic averages, difficulty and discrimination coefficients, and exploratory factor analysis were used to verify the factorial validity and the one-dimensional assumption, reliability coefficients, and Feldt's equation to find out the differences between the reliability coefficients, the validity coefficient associated with a test, chi-square test, correlation coefficients, and the use of analysis of variance for measurements the data were analyzed using the statistical programs (SPSS), (Itemman), (Xcalibre), and (BilogMG3).

the results of the study showed the following : the dimensional prediction method is superior to the other weighted methods, as the standard error value of the lord's method is (1.63), which is the lowest value, followed by the delta method (1.78).
