Introduction: Working memory (WM) plays a central role in cognitive functions and learning and its capacity predicts and determines other cognitive and academic functions. But, there is no specific scale that includes all 4 components of the multicomponent theory of Baddeley in children. Therefore, this study aimed to create a 4 components scale of working memory in children (WM-4CSC).
Method: This study was experimental and developmental research. First of all, based on the theoretical background, all assessment tools of WM  gathered. Then, based on experts’ opinions and their agreement (CVR and CVI scale), the tasks were selected and translated and coincided with the Persian language and age of the samples. 80 typical children (50 female, 30 male) and 10 children with WM deficits in 4-6 grades (8-12 years) participated in this study. For all participants, the examiner explained each task and when they got the instruction, the test was conducted. Data were analyzed with the One-Way ANOVA and Pearson Correlation Test.
Results: Results showed significant differences in all tasks of scale between 3 school grades and between typical and atypical children. But there were no differences between the two genders. There was a high correlation with test-retest scores and in convergent and diagnostic validities. Cronbach’s alpha was acceptable in all tasks. And a medium correlation was found in simultaneous criterion validity.
Conclusion: with respect to results, it was indicated that the 4 – components Scale of WM has reasonable developmental, retest, diagnostic, and convergent validities and good reliability and it can be used by other researchers. ​​​​ It is suggested to use this scale in more studies with greater samples to normalize it.
