This article analyzes various concepts regarding the efficiency of communicative competences for the purpose of socio-cultural integration. In addition, this article contains some of the results of our research, justifying the need to implement a Program for improving the communication skills from the perspective of the socio-cultural integration of adolescents. The experimental group consisted of 104 adolescents from pre-university educational institutions. Our understanding is that in order to cope with the rapid changes that are taking place in the world, it is necessary to approach the concept of education for sociocultural integration from a modern, broader perspective, with the role of making available to each student activities for optimizing the process of socio-cultural integration, focused on capitalizing on modern communication strategies, so that the student can discover the true values of diversity. From our perspective, advantageously placed as an observer, the teacher can greatly help the student by improving the communicative skills for the socio-cultural integration. In addition, due to the specificity of the educational environment, the difficulties of socio-cultural integration are rarely analyzed, and the multiculturalism analyzed only by the aspect of belonging to different ethnic groups, without having a methodology for assessing the level of socio-cultural integration or a Program for improving the communicative competences from the perspective of socio-cultural integration of students. In our vision, the supposed results of the research reside in the efficiency of the communicative competences for the sociocultural integration of the students who attend high school. The implementation of the Program of efficiency of the communicative and organizational competences from the perspective of the sociocultural integration of the adolescents ensures the prevention, the diminution and the overcoming of the difficulties of socio-cultural integration in the school environment; the application of the research results can be useful in the modernization of the school curricula in the intercultural context.
