Personal characteristics of an entrepreneur are always considered as the most important parameters on creating jobs and opportunities, successfully. This paper presents an empirical study on personal characteristics of students who are supposed to act as entrepreneur to create jobs in two major fields of engineering and social sciences at Islamic Azad University located in city of Zanjan, Iran. There are eight aspects of accepting reasonable risk, locus of control, the need for success, mental health conditions, being pragmatic, tolerating ambiguity, dreaming and the sense of challenging in our study to measure the level of entrepreneurship. We uniformly distribute 366 questionnaires among undergraduate students in two groups and analyze the results based on t-student test. The results confirmed that the students who were enrolled in social sciences accept a reasonable amount of risk, maintain sufficient locus of control, wish to reach prosperity and success in their carrier and lives and maintain a good level of dreaming. On the other hand, the students who were enrolled in engineering field have sufficient level of mental health care, they are pragmatic and are able to handle ambiguity and they can handle possible challenges in their jobs, properly.
