Since being established in 1995, the ISD Lions teams have been competing in tournaments between schools in Düsseldorf and wider Europe. Joining the Lions allows a student-athlete to improve physically, learn team-building skills and develop socially. The Lions participate in NECIS and ISST, two large inter-school international tournaments, while the NRW City Championships and the ISD Sportverein allow athletes to compete with others their age from across Düsseldorf and Nord-Rhein Westphalia.


This website is also home to ISD After-School Activities (ASA), groups centered around a shared interest that meet outside of school time to develop in an environment free of formal competition.
