The theoretical analysis of the essence and structure of the information competency of an interpreter in continuing education as subjects is proposed. The research techniques were document analysis, interviews, participant observation, work process analysis, and focus groups. This paper presents a brief overview of the information competency of an interpreter. The importance of the information competency in the structure of professional competency of an interpreter is acknowledged by the majority of modern experts. But there still exists the problem of determining the set of skills which present the information competency of an interpreter. This paper introduces the author＇s view on the problem of defining the essence and structure of the information competency of an interpreter.展开更多
