Particular concern about academic ethics in higher education and research institutions (HERIs) in Lithuania was addressed in 2009 by the national decision to establish an Office of Ombudsman for Academic Ethics and Procedures (Office). The decision was taken during the approval of the revised Law on Higher Education and Research by the Parliament of Lithuania. Following two failed attempts to appoint an ombudsman, the Office began to function in 2014. Since then, the ombudsman, alongside other state institutions, has been empowered to implement national higher education and research policy. At the outset of the Office activity it is important to consider how public HERIs institutionalise academic integrity, i.e. how they create an ethical environment within the academic community and what means are used to support it further. Collecting data from codes of ethics, regulations of academic integrity committees and interviews, data analysis shows that academic values manifest unevenly in teaching/learning and research. Most efforts concern the behaviour of students rather than the behaviour of academic staff (teachers and researchers). Moreover, ethics infrastructure gives a misleading image, as it lacks harmony and compatibility, despite the fact that there is a myriad of means to foster ethical behaviour. Universities should make greater effort to connect academic values with operations in teaching/learning and research.
