Students are considered the most essential internal stakeholders in the higher education sector. They play a significant role in quality assurance processes. This study aims to investigate students' engagement with and perceptions of Vietnamese higher education quality assurance. The study conducted an online survey questionnaire for undergraduate students in five major cities across Vietnam. The researchers utilised convenience sampling method to draw a representative sample from the target population. The 1,323 valid responses were collected and analysed using IBM's SPSS Statistical Tool. The results show that most of the Vietnamese students were aware of quality policy and quality assurance models implemented at their institutions. The purposes of quality assurance and the focus level of quality assurance were also reported on by the majority of respondents. However, the positive change as to the results of quality assurance implementation was not clearly observed by the students. The paper concludes that Vietnamese students were involved in several major quality assurance processes, and they were aware of only important quality assurance tools implemented at their university.
