Approaches to the application of intelligent information systems in the implementation of additional professional education programs are considered. The authors propose a generalized classification of these programs, including the following areas: content, structure, learning objectives, knowledge control model and form of organization, and describing a typed architecture of information systems consisting of several key modules (content, analytics and reporting, user management, communication). The lack of a unified classification and a systematic approach to the formation of continuing professional education programs makes it difficult to create effective intelligent information systems capable of flexibly adapting the educational process to the requirements of the labor market, current professional standards and the individual needs of students. The purpose of the work is to demonstrate the impact of intelligent information systems modules on each of the categories of the proposed classification of continuing professional education programs in order to increase the effectiveness of the educational process, personalize it and meet the current needs of the economy and the professional environment. Special attention is paid to the methodology for quantifying the contribution of each module to certain aspects of the classification of additional professional education. The results obtained make it possible to develop an effective strategy for designing systems in additional professional education, improving the quality and personalization of training, as well as strengthening the theoretical and practical foundations for their further development.
