The development of social intelligence is a delicate issue among teenagers. Insufficient social intelligence leads to social disorientation which may impede students' capacity to grow positively and to understand the reasons for their actions and the logic of the development of complex situations of interpersonal interaction. This study aims to evaluate the technology of pedagogical support in increasing the social intelligence of adolescents in a primary school's educational process. The Mann-Whitney test was used to find differences between subject groups and the Wilcoxon T-test was used to evaluate the social intelligence development programme. The study involved 40 students from Almaty's secondary school no. 76. The social intelligence of adolescents in the school environment was improved through the effective application of technological and pedagogical support in the teaching process. Education policymakers assess the social intelligence of adolescents in their own countries and institutions and make international comparisons.
