Education directly affected students' futures. However, the roles of students in the educational process, decision making, and development were generally less than other stakeholders. The paper proposed an optional standard in order to formally and systematically include the student engagement into CDIO framework in four spheres of engagement – (1) the management, (2) provision of education, (3) research, and (4) industry and society at the degree of partnership at least. With this platform, the optional standard would directly support most of the main standards in planning, operation, and development of activities and evaluation.
