European and Euro-Atlantic integration is the geopolitical choice of the Ukrainian people and of Ukraine as the sovereign state, their desire for good governance, peace, and security; moreover, since 2016 this course, as well as the European identity, have become part of the Ukrainian Constitution as the provisions of its Preamble. This course’s implementation requires the appropriate comprehensive activities on its enforcement, including legal harmonization and huge changes in different spheres of civil and public life. This activity should be focused on the understanding and spreading in Ukraine of the common European values, principles of unity and diversity, and common cultural, historical, and legal heritage. The key role in these processes is played by HEIs, which, based on cooperation, can have a great impact on the civil environment and public system. The exchange of experience is the shortest way to reaching the aim, especially when it comes to the countries that have already passed the path of EU/EA integration like Poland and Lithuania. Their HEIs have huge scientific and educational expertise in the support of the EU/EA integrational process, which will be very useful for the Ukrainian HEIs. This project is aimed at increasing the capacity of Ukrainian law schools in providing students with the knowledge and competencies necessary for the legal support of the European and Euro-Atlantic integration of Ukraine by highly professional teachers and according to modernized syllabi of core legal disciplines, as well as dissemination of impact onto the wider civil and political environment (secondary school teachers and public servants).
