The aim of this study is to derive the criteria for the final image of the Wexler scale, the Jordanian image of children's intelligence for pre-school and primary school for the age group 4 - 6.5 years. The study population consists of all children in the Hashemite Kingdom of Jordan for the age group 4 - 6.5 years. The sample of the study consisted of (1491) tests distributed by gender, age group, special education groups and the area of residence for the years 2016-2019, who were chosen in a stratified randomized manner, as the study tool was used, which is the Wexler scale of children's intelligence for pre-school, the Jordanian image. The indications of the validity of the scale were reached through the validity of the content and the correlative validity, as the correlation coefficient between the Wexler-Binet scale of intelligence reached the Jordanian image (0.71) and the illustrated IQ scale (0.72). Factor analysis found that there are two factors (verbal, performance) explain (50.98) of the total variance. As for the results of the discriminatory honesty, it showed statistically significant differences between ordinary children and special education groups in favor of ordinary children. The results also showed the existence of statistically significant differences according to the age group and in favor of older age. There were also indications of the stability of the scale by the half-segmentation method and the stability by the internal consistency method, where the reliability coefficients ranged between (0.86 - 0.89) for the sub-measures and (0.92) for the total degree. The criteria for the final image of the scale were also derived by converting the raw score to a weighted score for the sub-tests and then to a mean deviation intelligence ratio of 100 and its deviation 15. The study recommended the use of the Wexler scale in evaluating children for pre-school and primary school and taking appropriate decisions.
