Welcome to the International Summer Science School Heidelberg!

The International Summer Science School (ISH) is a project for young people from Heidelberg's sister cities and partner organizations who are interested in natural sciences and would like to get a practical insight into the laboratories of renowned research institutes. The participants should be at least 16 years of age and need to live/ be in school in one of our sister cities.

On this website, you will find background information about the ISH, Heidelberg and its research institutes and you can get in contact with the organizers and former participants.
