Purpose: The purpose of this paper is to analyse the creativity level of business administration undergraduates who have attended an entrepreneurship seminar in contrast to those that have not. Design/methodology/approach: Using two samples of Spanish students, the factors that condition the creation of new start-ups are analysed. A survey following the creativity items from the Kirton Adaption-Innovation (KAI) inventory was employed for a start-up seminar students and a control sample. Non-parametric tests were carried out on the responses. Findings: The results show that Spanish business students' entrepreneurial intentions are not conditioned by entrepreneurial courses, parental self-employment or by their creativity level. However, there are differences in creativity level by genders for their future ability to start-up a company. Practical implications: There are no external constraints on not being an entrepreneur, who plays a fundamental role in the future of a country and it is a way to reduce current youth unemployment rates. Social and educational implications are also presented. Originality/value: The use of the KAI inventory as a proxy of creativity index is original in the research. Moreover, this study contributes to a better understanding of the factors in becoming an entrepreneur, through exposure to creativity, growing up around businesses and awareness of individual creativity index. Integration of university courses with entrepreneurship actions will be of interest to the society development.
