The development of IT has led to the emergence of digital educational platforms that offer a variety of training courses. Among such courses are information hygiene courses relevant for Ukrainian citizens (the hybrid war causes demand to counteract information influences). The problem becomes the choice of such a course that would best meet the needs of the consumers of the course. The task of choosing a course is unstructured and multicritorial. Therefore, to solve it, it seems reasonable to use the Saaty (hierarchy analysis) method to solve problems of choosing the best alternative among the proposed ones. The authors substantiate the feasibility of using the Saaty method to select an online course and build a model of the educational task for choosing an online course according to the selected criteria. The model is based on five criteria and three alternatives (three various courses, A1–A3). Expert assessment from three experts is presented. The results of the pedagogical experiment are given (data from three student groups). The Saaty method has proven effective in solving choice tasks in the educational process. Therefore, mastering the method is recommended for the teacher, the mentor, or the facilitator.
