At Worcester Polytechnic Institute (WPI) a Global Perspective Program (GPP) has evolved that provides an international experience for most graduates. Currently more than half of WPI students travel internationally to do academic work. WPI sends more engineering students abroad than any other U.S. university, and it is ranked second in the nation for doctoral universities for the percent of its total student body that studies abroad. A unique program aspect is that students simultaneously satisfy WPI's general education and engineering academic requirements while abroad. The GPP grew from the basic project-based educational structure implemented over 30 years ago. In this paper, the authors describe the structure and operation, but will emphasize the multilevel assessment process used to understand student learning and improve the program. They outline the assessment process that continuously challenges their institution to demonstrate that its curriculum, in its design and delivery, is in fact meeting the Accreditation Board for Engineering and Technology (ABET) standards, and in doing so, preparing WPI graduates for a career in engineering that is now global.
