The results of the activities of higher education institutions in the field of additional professional education do not always reach high rates, which affects the process of implementing the state policy of labor market modernization. The hypothesis of this study was based on the assumption of a complex of conditions, in which the offers in the additional professional education market are formed, and which can be considered as a group of related but not homogeneous factors. To form the empirical base of the study, the authors selectively collected open data posted on the official websites of educational organizations on the Internet, which were then statistically and meaningfully processed using the systemic method. As a result, it was found that offers in the market of additional professional education services are formed under the influence of a number of objective factors, which are designated in the study as “standard, progress, market and fashion” factors. The application of this model to the analysis of the actual state of the additional professional education market made it possible to formulate three principles of effective organization, abiding by which some educational organizations obtain benchmark results: fields-of-study differentiation, functions delegation, and price diversification. Thus, the study made it possible to identify the most effective directions of the organizational activities of universities in the field of additional professional education and to formulate a number of provisions of practical significance. The prospect of the study is a factor analysis of further changes in that part of the additional professional education market, which is made up of state higher education institutions.
