The objective of this study was to find out how effective the use of cloud technologies is in the formation and development of critical thinking in future lawyers. An experimental model using cloud technologies was tested in training courses in the special (Civil Law, Fundamentals of Administrative Law) and general (English for Specific Purposes, Business English) subjects of the educational professional programme for training specialists of Specialty 081 "Law". The method of test control and the method of component analysis were used to diagnose the level of academic performance of students selected for the pedagogical experiment in the training courses. To accomplish the research objectives, the results of the author's tests (seven control points) performed by students of both groups. IBM SPSS Statistics 25.0.0.1 software was used to analyse the quantitative data. Two-tailed P-value and Student's t test were calculated for statistical processing of experimental data. The study showed the effectiveness of the use of cloud technologies for the formation and development of critical thinking in future lawyers. The authors conclude that the use of cloud technologies in the professional and linguistic training of lawyers also facilitates feedback, which increases students' educational motivation and allows for monitoring changes in students' personality development.
