Purpose: The purpose of this study is to investigate the factors influencing the entrepreneurial intention (EI) of Higher Diploma (HD) students in Hanoi, Vietnam, addressing a notable gap in the literature regarding this specific demographic. Design/methodology/approach: Surveys were conducted using both web-based platforms, such as Google Forms, and distributed questionnaires. In total, 411 valid responses from HD students in Hanoi were collected. A convenient sampling method is utilized, considering the distribution of students across various demographic variables to ensure the reliability and representativeness of the study. The Theory of Planned Behavior (TPB) was employed. Multiple regression in SPSS is used to analyze the collected data. Results and discussions: The analysis results unveiled that all scrutinized factors, including Attitude Toward Behavior, Perceived Behavioral Control, Subjective Norm, Entrepreneurial Self-Efficacy, Closer Valuation, and Social Valuation, exerted a positive and substantial influence on HD students' Entrepreneurial Intention (EI). Notably, the six factors collectively accounted for 40.6% of the variance in entrepreneurial intention observed among the respondents. Research Implications: The findings hold valuable implications for policymakers, educators, and stakeholders, guiding the development of targeted interventions aimed at fostering entrepreneurship among HD students. By leveraging these insights, they can design tailored initiatives to promote entrepreneurship, potentially leading to enhanced economic development in Vietnam. Originality/Value: The findings provide valuable insights for educators, policymakers, and stakeholders involved in entrepreneurship education and support programs, helping them tailor interventions to effectively cultivate an entrepreneurial mindset among HD students. Furthermore, the study adds to the broader understanding of the psychological and social factors that shape entrepreneurial intentions, contributing to the advancement of knowledge in the field of entrepreneurship research.
