The aim of this paper is to carry out an empirical study on students' satisfaction with online assessment and testing at some foreign language faculties at the University of Social Sciences and Humanities-Vietnam National University-HCM (USSH-VNU-HCM). Data were obtained by giving questionnaires to students at three faculties: Faculty of English Linguistics, Faculty of Russian Linguistics and Faculty of Chinese Linguistics. The questionnaire received 201 valid responses. Quantitative techniques were applied to find out some highlights from the results. (1) Students rated their perceived satisfaction from online testing as 4.08 on the 5-point Likert scale.(2) T-test showed that in comparison between faculties, students of the Faculty of English Linguistics and the Faculty of Russian Linguistics had similar views on the application of online assessment and testing. In contrast, the degree to which students of the Faculty of Chinese Linguistics supported online testing significantly differed from those of the other faculties. (3) Findings proved that most students in the experiment approved the continuation of the online assessment and testing after the pandemic, yet ANOVA results showed a considerable difference according to the faculty where students reside. (4) Correlation of contributing factors and students' willingness towards online testing continuation showed that there were strong associations between students' willingness and the three groups of factors: test organization factors, test content factors and grading factors. The study has obtained profound feedback from students, which helps to identify the challenges that online assessment and testing may encounter in the future.
