Entrepreneurial thinking has become a mantra for many programs and initiatives that aim to prepare young people for the future. This is because entrepreneurial skills—like the ability to take initiative and think on your feet, critically solve problems, and communicate effectively—are increasingly viewed as essential for career success. But how do we know whether young people are acquiring these skills? Until now, there has been little research to guide efforts to assess entrepreneurial thinking in youth. In recent years, the Network for Teaching Entrepreneurship (NFTE) has been working to fill this gap by developing and testing the Entrepreneurial Mindset Index (EMI)—a tool to measure attitudes, behaviors and beliefs associated with being an entrepreneur. The EMI is currently in use with students in NFTE programs in schools across the United States and abroad. Our new paper, Measuring Entrepreneurial Mindset, presents findings on the utility, reliability and validity of the EMI, highlighting its potential as an innovative and effective assessmenttool in the entrepreneurship education landscape.
