The Université Catholique de Lille belongs to the network UDESCA, Union des Établissements Supérieur Catholique (Catholic Higher Education Establishments Union), which has united, since 1973, the five not-for-profit higher education institutions that the Holy See calls Catholic Universities and which are commonly called the “Cathos.” These private institutions are located in Angers (UCO), Lille (UCL), Lyon (UCLY), Paris (ICP), and Toulouse (ICT).
The Université Catholique de Lille is also affiliated with the European Federation of Catholic Universities (FUCE). The FUCE was established in 1991 with the aim of contributing to the Catholic Universities network by supporting the progress of European integration, which was then nearing completion in the European Union.
At the end of the 1990s, the FUCE undertook a comparative study highlighting the diverse richness and similarities between Catholic universities across Europe. This analysis stressed the need to strengthen existing links even after the establishment of the Bologna Process in June 1999 to make the academic certifications of European universities comparable and encourage the mobility of students, teachers, and researchers.
The FUCE unites the Catholic universities of Europe and Lebanon.
The Université Catholique de Lille is part of the International Federation of Catholic Universities (IFCU). The IFCU is a global organization regrouping Catholic universities worldwide. It supports collaboration and exchange between these academic institutions and defends the principles of Catholic education in higher education. The IFCU facilitates the coordination of academic activities, encourages research, strengthens the links between its universities, and thus contributes to the advancement of education and society at a global level. Several hundred institutions around the world are part of it.
The Université Catholique de Lille belongs to the network Campus France.
Campus France aims to promote the French educational and vocational system on the international stage: to welcome foreign students and researchers, including through the facilitation of visa issuance and accommodation; to administrate the scholarships, internships, and other international mobility programs of students and researchers; to conduct studies and analyses of the international mobility of students and researchers; and to animate France Alumni, the network of former international students in French higher education.
