The purpose of the work is to determine the role of web technologies to ensure the formation of multilingual competence within the CLIL approach. For this purpose, a survey was conducted among students of various specialties, however, with a special emphasis on students of technical universities. The survey was conducted among 58 students. Questionnaires were used, including questions about the use of web applications in various forms of education. The results of the survey showed the high efficiency of using web applications in CLIL courses for the formation of both language competence and subject knowledge. The CLIL method combined with modern web applications proved to be an effective tool in the students' learning process. The implementation of the program of this approach allows not only the problem of educational overload, but also the strengthening of the general development of students, including their language skills. In the conclusions, it is noted that for the successful implementation of the CLIL program, it is necessary to provide students with essential terms and to acquire a foreign language and the availability of trained teaching staff.
