National Institute of Technology, Sendai College (Sendai KOSEN) has been engaged in global education for students by offering them internship programs at overseas universities since the early 2000s. Currently, several programs are being implemented, e.g. short- and long-term internship, internship at foreign companies and so on. By dispatching students to overseas internship programs (OSI), we are focusing on the development of the global mindset of the students. A continuous survey on the Generic Skills (GSs) of students using an objective method, meanwhile, started in 2014. Since five years have passed since the survey started, it has become possible to measure the growth of Generic Skills objectively before and after their overseas internship. It is reported the results revealed that their GSs trend before dispatch of students who want to participate in OSI and growth characteristics of their GSs between before and after dispatch. By utilizing this PROG continuous survey, it is thought that effective and individual pre- and post-support can be realized for students who will participate in OSI.
