Entrepreneurship education (EE) is widely regarded as a critical tool for fostering entrepreneurship. However, the stability of its effects on entrepreneurial intention (EI) remains underexamined. Drawing on a longitudinal approach, this study investigated whether participants’ EI persisted or changed six months post-program. Guided by theoretical perspectives highlighting intention as a key driver of entrepreneurial behavior, we propose that action-based EE fosters both EI and a sustained commitment to entrepreneurial pursuits. We employed a quasi-experimental design with a control group, collecting pre-, post-, and six-month follow-up data. The treatment program will be offered to university and college students across Japan three times between 2021 and 2023. Delivered online in 2021 and offline thereafter by the same instructor, it aims to foster entrepreneurial behavior (EB) by teaching and practicing the know-how of entrepreneurial actions, emphasizing experiential learning and reflection. The findings showed that EI increased significantly after the program but declined six months later unless participants continued their EB. In contrast, control group members who lacked structured action-based practices exhibited decreased intentions. These results underscore the importance of ongoing experiential activities for maintaining elevated EI over time.
