The article proposes an approach to the application of case-based method for the creating of digital accessibility competencies in the e-learning. The following method tools have been developed: a scheme for the creating of digital accessibility competencies using the case method, a procedure for solving a case, a template for describing a case and a collection of 11 cases. The original data sets posted in the public domain were used as empirical material for situational tasks. These data sets contained the results of: expert assessment of the e-learning digital accessibility; analysis of the students’ needs in e-learning digital accessibility; assessment of the teachers’ motivation and readiness for providing e-learning digital accessibility; analysis of the content of digital accessibility web services; analysis of the regulatory bases in e-learning digital accessibility. During the solving of each case, students should perform their own study of the data set according to the task, compare the results with those published earlier, and, if possible, identify additional patterns. In teaching the basics of digital accessibility, it is advisable to combine the case-based method with traditional forms of learning (lectures, traditional practical work and testing). The developed tools can be used by teachers to design their own situational tasks using open data.
