The doctorate forms the basis for academic careers and the regeneration of academia, and has increasingly become important for other sectors of society. The latter is reflected in efforts on institutional, national as well as supranational levels to change and adapt the doctoral degree to new expectations. As doctoral education is embedded in research, changes in governance and funding of research further affect the doctorate. The evaluation of the doctoral thesis appears, however, to have remained true to the academic tradition: an examination committee exercising their gatekeeping in a ceremonial setting. This study sets out to explore doctoral examination committees' evaluation practices. Insights were gained through six focus group interviews with experienced examination committee members at three large research-intensive universities in Sweden. Of particular interest is how the object of evaluation is formed, the nature of the boundary-work conducted, and variations in examination practices related to different and changing conditions for research and doctoral education. Our results show how the object of evaluation emerges through a gradual interpretation of the thesis and defence, becoming more complex and nuanced as the process of evaluation progresses from its initial stages to the final closed discussions of the committee. The finalised object of evaluation, only fully present at the conclusion of the closed meeting and hence transient in nature, encompasses the research contribution, educational achievement, and academic competence of the candidate. Furthermore, the boundary-work conducted in this process often transcends the object of evaluation to include also supervision and the local context for doctoral education and research, and hence contributes to upholding, and potential changing, norms in research fields, educational contexts, and academia at large. This extended boundary-work intensified as problems and inconsistencies were discovered during the evaluation process. The ceremonial staging underscored the gravity of the decision and the extended boundary-work. Despite changing conditions for the doctorate, our findings highlight the importance of the practice of evaluation committees, and the disciplinary communities to which they belong, for upholding and negotiating norms in academia.
