 This paper discusses the use of computerized adaptive testing, CAT, in an educational electronic environment at maritime higher education institutions. It compares CAT with traditional testing methods, evaluates the presence of problems in the educational process, and assesses the level of control and learning outcomes. Examples of activities to form communicative competencies of future maritime professionals are also discussed. The paper concludes that CAT has a positive effect on the development of communicative competencies of future ship engineers. Further investigation into the use of CAT in maritime education establishments could involve the use of simulation technologies such as virtual, augmented, and mixed reality.
