At the National Institute of Technology, Sendai College, we are continuously examining the generic skills (GSs) of students using PROG, an objective assessment test. We report the results of the GS growth characteristics of college students from their admission to graduation. We will introduce how we use the results of the survey for the students and faculty members, both those that are currently being implemented and those that will be implemented in the future. The feedback of the results of the surveys makes it possible to quantitatively evaluate the growth of the students' GSs, which is difficult for students to recognize and to foster efficiently by themselves. Besides, the feedback of these survey results can quantitatively evaluate the students' GS training, which is difficult for teachers to evaluate accurately and train efficiently. Therefore, the efficiency and quality of our college education can be improved.
