Background. The study highlights a gap in research on politeness in EFL academic interaction, noting that previous studies focused on classroom discourse analyses. It emphasizes the need to examine real interaction during thesis defenses, particularly the influence of institutional power on sequential politeness practices in high-stakes assessment. Purpose. This study examines the distribution and negotiation of politeness strategies between examiners and candidates during EFL thesis defenses, highlighting the interactional construction of institutional authority and face management in academic assessment. Method. The study combines quantitative and qualitative analysis. It is based on eight undergraduate thesis defense sessions involving eleven examiners and eight candidates. The analysis covers 772 utterances coded according to Brown and Levinson’s politeness framework. The quantitative results show how politeness strategies were distributed across participant roles, while the sequential discourse analysis shows how these strategies were used and negotiated during the defense interaction. Since the utterances come from the same speakers and sessions, the statistical findings are interpreted cautiously and used mainly to identify patterns in the data. Results. The findings revealed patterned variation in politeness strategy use between examiners and candidates, χ2(3) = 23.94, p < .001, with a moderate association (Cramér’s V = .346). Data showed that negative politeness was the most dominant strategy (58.5%). Candidates relied heavily on negative politeness (73%) to minimize imposition and display deference, whereas examiners employed a more varied distribution of strategies, including positive politeness (34%) and bald-on-record forms (20%), to manage evaluation, procedural control, and institutional authority. Sequential analysis further showed that examiner authority was most visible during questioning and challenge phases through turn management, epistemic stance-taking, interruptions, and repair sequences. Conclusion. In summary, these results demonstrate that politeness strategies function as interactional resources for negotiating institutional power and evaluative relationships in EFL thesis defenses. Thus, the findings contribute empirically to research on institutional discourse and pedagogically support the inclusion of pragmatic preparation in EFL thesis defense training. © 2026 National Research University Higher School of Economics (HSE University).
