This study focuses on exploring the issue of ensuring quality higher education in the conditions of Russia's invasion of Ukraine. It synthesizes and analyzes literature sources, legal documents, secondary data, original (survey) data, and the author's experiences with enhancing the quality of higher education. Using analysis of the legal documents, such as the National Doctrine of the Development of Education, the Law of Ukraine 'On education', and the Law of Ukraine 'On higher education', I study the legal framework for Ukrainian higher education. Using secondary data obtained from online sources, I find irrefutable evidence of mass destruction from Russian military aggression on educational institutions of Ukraine and the educational process in general, and specific initiatives from the Ukrainian state, Ukrainian universities, and international institutions to support the Ukrainian higher education system in wartime conditions. Using original data collected through surveys, I present first-hand information on the processes of changes in higher education in Ukraine under the conditions of Russia's ongoing military aggression and the issue of ensuring quality higher education through the prism of the experience of students at the Ivan Franko National University of Lviv. Using the author's personal teaching experience in the implementation of joint global classrooms, I analyze the possibilities of developed partnerships for motivating students and ensuring quality higher education in the conditions of war. Based on the analysis and synthesis of secondary data, I identify the main responses of the higher education system of Ukraine which enable it to maintain the quality of higher education as the realization of the Sustainable Development Goals during the war, namely (i) improvement and wider implementation of an online education system; (ii) organization of work of higher education institutions relocated from the occupied territories to territories controlled by Ukraine; (iii) support of international institutions; and (iv) partnership programmes with partner universities. The analysis of the results of the survey of students highlighted that the top priority of a Ukrainian university during wartime should be the safety of all participants in the educational and research process and high-quality education, and the most serious problems that create obstacles to ensuring the quality of education are the distressed psychological states of the participants in the educational process and organizational issues in the conditions of military aggression. By analyzing the experience of the implementation of joint global classrooms format, I also highlight that this format can be an effective additional measure in motivating students and ensuring the quality of higher education in the difficult conditions of war, and a developed partnership plays a crucial role in its implementation.
