The term "entrepreneurial mindset" is often included in the program objectives of engineering entrepreneurship programs. However, the definition of the term has been argued and debated by many in the community and in the literature, leading to challenges with how to best design assessment of engineering entrepreneurship programs. The purpose of this paper is to present a researchbased approach to conducting assessment, discuss the various definitions of entrepreneurial mindset including how the term is fraught with construct confusion, and to propose an approach to assessing entrepreneurial mindset that focuses on specific attributes rather than the omnibus construct.
