By employing and adopting the measures from the studies of Han, Park et al. (2013) and Valentine and Fleischman (2008), the present study aims to examine students’ awareness of professional ethics. Students with different majors are the studied subject. Reviewing literature and conducting the empirical survey show some noteworthy points. Firstly, not much can be found on professional ethics in Vietnam, in terms of academic studies and instructions (i.e. codes of conduct) for occupations. Secondly, from students’ perspectives, individual ethical standards do not play any role in their awareness of professional ethics. As a consequence, a systematic educational program professional ethics requires a priority significantly.
