The Pontifical University of John Paul II in Krakow develops international cooperation thanks to the Erasmus program, realizing a total of 56 mobilities. The university also accepted over 20 mobilities from partner institutions. The program’s objectives included student mobility (SMS, SMP), teaching (STA), and training (STT) for staff. Scholarships were awarded to 20 students, 7 for internships, and 15 academic and 14 administrative staff. The university has achieved numerous benefits, including increased mobility, establishing new partnerships, and improving language skills. The COVID-19 pandemic prompted the use of online tools, leading to greater involvement in international projects, such as organizing the first English-language School by the Faculty of Philosophy and the International Center for Research on the Phenomenon of Solidarity.
