Mechanical engineering curriculum has been studied through curriculum tree model and requirement of prerequisite courses. We analyze curriculum, curriculum system, course outcomes, design education of mechanical engineering programs in korean and foreign universities and present results to improve current curricular system. Current study would analyze, develop, and help mechanical engineering programs to prepare better curriculum for engineering education accreditation, to maintain accreditation. Through this analysis we try to provide reasonable model curriculum structure, prerequisite courses and necessary information about establishing various sub-major curriculum in mechanical engineering.
