The aim of accrediting ‘the education program for engineers’ by JABEE is to improve the quality of education and to guarantee its quality based on international standards. While the JABEE accreditation system works in Japan, it is necessary to verify the effect of accreditation and its social evaluation. More concretely it is to see if the abilities of students were raised in an improvement of education or not. In this paper, it is shown how the Colleges worked with the program for accreditation and what results were obtained, particularly focusing on the case of Tokuyama College of Technology. Also, some factors for acquiring accreditation are considered.
