Expand your knowledge, gain international experience, and explore global challenges. From summer schools and online courses to virtual exchanges, Leiden University students at all levels (bachelor’s and master’s students, and PhD candidates) can participate in a range of learning opportunities.

Summer schools

Learn from experts while connecting with peers from across Europe. Take part in hands-on workshops and get inspired by new perspectives — all while discovering a new city and university. Many summer schools offer funding or subsidies, making it easier for you to participate.

Calls to join summer schools often open in early spring.

In 2026, three summer schools will take place at University College Dublin from 15-19 June, on the topics of One Health, Sustainability and Data Science & AI. There will also be a Future Materials summer school in Bologna (date TBC).
