The purpose of this study is to examine the impact of personality traits on perceived behavioral control after entrepreneurship education in sustainability. Recent studies underlined that perceived knowledge and abilities are important outcomes of education, particularly in the context of sustainability. This study employs a pretest/posttest questionnaire (before and after the course), distributed in a convenience sample of 271 students of a business administration department. The results indicate that the students who benefit more from the course have higher levels of openness, contentiousness, extraversion, agreeableness, and lower levels of neuroticism and risk aversion. Our results highlight the importance of tailoring entrepreneurship education to individual personality profiles to maximize its effectiveness. The importance of perceived behavioral control is critical to the outcomes of education and crucial (as a psychological factor) to the formation of positive entrepreneurial intentions.
