The article reveals the substantive aspects of the Foresight methodology of social forecasting of the development of the education system as a complex, dynamic, open system from the point of view of a systematic approach. It is assumed that the education system is a central social institution, which, being associated with the transmission of knowledge, has to, in order to form a holistic personality of human beings, also support its own systemic complexity, as well as correspond to the complexity of the entire structure of society. The paper emphasizes some substantive difficulties in the work of experts in the framework of Foresight studies, as well as the need to take into account the value aspect when predicting the education of the future.
