This study is a design and delivery of a comprehensive re-entry training program which has been implemented to meet the needs of returning French engineering grande ecole undergraduate sojourners. With particular attention to the historical and specific character of a grande ecole's interdependent relationship with industry and professional training as an integral part of the educational design, this program has been specifically conceived as a semiautonomous, in-house institute for advanced intercultural training and studies with the combined aims of a) meeting the immediate and longer-term needs of returning sojourners and b) enhancing intercultural awareness at the school generally. This study focuses specifically on the re-entry program delivered by the newly created Winter Institute of Intercultural Communication (WIIC) as the capstone innovation in the broader developmental curriculum redesign scheme for grande ecole students. The Institute now provides the necessary re-entry follow up after an extensive pre-departure training program and six months experience abroad as well as providing a workshop for moving on to more advanced levels of intercultural communication issues.
