Background. Undergraduate and graduate students of technical universities are aware that knowledge of at least one foreign language increases their competitiveness in the labour market. At the same time they do not show much interest in studying this academic subject. Development of effective ways to increase motivation to learn a foreign language is an urgent and unresolved task. Objective. Aim of the work is to trace the correlation between the level of foreignlanguage professional communicative competence of students and their motivation to study a professional foreign language in the traditional and triplex form of education. Methods. The research included three stages: the first – diagnostics of the educational motivation of undergraduates; the second – identification of the main motives for learning a professional foreign language in master’s groups; the third – determination of the level of foreign-language professional communicative competence. Results. A significant increase in motivation to study a professional foreign language in a group with a triplex form of education was revealed. The level of foreign-language professional communicative competence in this group also turned out to be higher compared to the group with the traditional form of education. Practical significance. The results of this study can be used to optimise the educational process based on the awareness of the dependency of the level of academic performance in a foreign language to the level of motivation to study it
