Standardization of Reynolds Intellectual Assessment Scale in PreSchool Children

This Research aimed to "standardize the second version of the Reynolds Intelligence Measurement Scale in Students of Preschools" and the main question is thus elaborated whether the second version of the Reynolds Intelligence Measurement Scales in Preschools Students has favorable psychometric properties? The present research community consists of all preschool students people. In the present study, 400 individuals were selected. Finally, the findings showed that the second version of the Reynolds Intelligence Measurement Scale using the alpha-Cronbach method was higher than 0.89 and the twohalf Spearman-Brown correction test was 0.86, indicating a favorable internal consistency, and also , The stability coefficient in the present Research is higher than 0.87, which indicates the repeatability of the Instrument. Also, by analyzing the orthogonal hierarchy, it was discovered that "fluid intelligence" and "crystalline intelligence" were identified as "intelligence profile" in Preschools students, "intelligent intelligence"
