The formation of future engineers' integrative readiness is a relevant problem: a) an engineer works in the open world and performs professional tasks that have significance for different countries or even for the whole planet; b) import substitution tasks lead to the need to study and apply world experience in the field of technical solutions. Thus, we have developed a system to form future engineers' integrative readiness for professional activities. The system needs to be verified to become part of scientific knowledge. The article aims at characterizing the verification procedure of the results gained through the scientific research of the problem of forming future engineers' integrative readiness to solve professional problems in a foreign language. The article describes the steps and means of the experiment (criteria, levels, indicators, measurement techniques, experimental methods) and the technology of forming future engineers' integrative readiness to solve professional problems in a foreign language. The results of verification are presented. This study has shown that the results of theoretical research (on the system of forming future engineers' integrative readiness to solve professional problems) can be recognized as true knowledge.
