Executive functions are psychological processes of great importance for proper functioning in various areas of human development, including academic performance. For this reason, from both clinical and educational perspectives, there is great interest in how they are assessed. This article describes the development and standardization process of Yellow-Red, an instrument for directly assessing executive functions in children between 6 and 11 years of age in a playful format using digital support. The test was based on a three-factor model of executive functioning: inhibition, working memory, and cognitive flexibility. Yellow-Red comprises six subtests: cognitive inhibition, behavioral inhibition, auditory working memory, visual working memory, cognitive flexibility, and a global assessment test of executive functions. The test was administered to 245 boys and girls between 6 and 11 years of age. Along with the Yellow-Red subtests, gold standard tests were applied for each of the executive functions assessed. The test's psychometric properties are powerful in both reliability and validity evidence. The reliability indices are all greater than 0.8. As evidence of convergent validity, correlations were established between the tests, and the tests considered gold standards. All correlations were significant, with values ranging between 0.42 and 0.73. On the other hand, the factor structure of the test was analyzed using confirmatory factor analysis. Although it is possible to demonstrate the progressive differentiation of the factor structure with age, it was only possible to find two factors at older ages, one for inhibition/flexibility and one for working memory.
