In the European Higher Education Area, ensuring a comparable quality of education is one of the conditions for the rapprochement of European countries in the formation of the Single European Educational and Scientific Space. The purpose of the study is scientometric assessment of the scientific orientation of the acts of domestic legislation on the assessment of the internationalization of doctoral education. Recent experience in reforming doctoral education systems in developed countries has shown that while maintaining national sovereignty and national diversity of their organizational systems, international integration opens up prospects for improving and enhancing the quality of training of highly qualified scientists, increasing access to scientific degrees, development of international scientific and technical cooperation. In the last twenty decades, internationalization in developed European countries has become a key priority for doctoral education and an important component of improving its quality. The level of internationalization of doctoral education varies in different countries and develops in different forms. This is the individual mobility of graduate students, doctors and faculty for educational purposes (organized - in various national and international programs, as well as spontaneous - as a result of activating market mechanisms in the market of educational and research services); mobility of educational programs and institutional mobility; formation of new international standards of educational programs; integration into international dimension curricula; institutional partnership - creation of strategic educational alliances.
