Content and Language Integrated Learning of a foreign language is one of the topical areas of teaching in higher education. This model simultaneously realizes two goals: on the one hand, the study of a foreign language and on the other hand, the specialized content of students. In the scientific literature, many authors reveal problem areas and debatable aspects of the implementation of integrated learning, the consideration of which affects the teaching methods. In this work, the author can substantiate a number of hypothetical conditions used for normal learning. To such conditions: a) the competence of the teacher of an integrated course in a foreign language, profile specialty and teaching methods of language and profile disciplines; b) selectively thematic content of training within the framework of the discipline “Foreign language for professional communication” is carried out on the principle of supplementing and expanding the subject-matter content of training in specialized disciplines; c) the subject content of the integrated course to reflect the specifics of the specific profile of students' training; d) the level of proficiency in a foreign language by students should be in the range B1-B2; e) professional cases act as a methodological dominant. In the work, the conditions are described in more detail.
