This article clears and specifies the method of cultural congruence determination of a junior schoolchild in the form of the quantitative and qualitative characteristic description concerning the levels and the content of cultural congruence factors. The cultural context is analyzed with the typical rules contained in it, which are faced daily by junior schoolchildren, exist in it, interact with each other in the conditions of general education schools in our country. The cultural congruence of a primary school child is characterized by three levels of development: interactive (133-144 points), reflective (98-132 points) and perceptual (0-97 points), and also includes six factors grouped from typical rules for this age, which are included in normative situations: Social interaction, Academic competence, Self-control, Obedience, Self-service and Regulation. These factors reveal the features of a child's compliance with a normative situation and determine the level of cultural congruence among junior schoolchildren. They develop in the process of leading activity (educational one) and are associated with the new formations of junior schoolchildren: arbitrariness and self-control, reflection and the ability to plan (an internal action plan).
