(ISD) is a nonprofit, independent, coeducational day school located in Kaiserswerth, Germany, a historic suburb of Düsseldorf.

The founders, including Evelyn and Hank Zivetz, Ruby and David Prior, Polly and John Briwa, Alex McNaughton, and Dotty and Aaron Smith, were parents of the 32 original students, all in grades 9-12.

AISD's first location was in several unused rooms on the top floor of the offices of the occupying British forces and the NAAFI (Navy, Army and Air Force Institutes) in Düsseldorf's Nordpark, in a building that no longer stands today[4] In 1971, construction was completed on the new AISD campus, and the students and teachers relocated to its present location in Kaiserswerth, on the site where the school's North Building now exists.

One of its largest contributions was the production of the annual musical, led by Dotty Smith, and performed by students from all of the grades.

The musicals were performed to sold-out audiences over three nights each spring, and rehearsals were part of the after-school activities for most of the year.

In 2003, the process was completed, and the IBO authorized ISD as one of only 39 schools worldwide able to offer the entire IB program.

[7] Alternatively, students may choose to enroll in separate IB courses, resulting in receipt of individual subject certificates.

Students and teachers provide educational and financial support, and engage in a cultural exchange programme with the local school community in Monduli.

[11] In late 2018, ISD was featured in an article by the tabloid Express regarding the school tuition as it relates to state subsidies.

[15][16] Further criticism was attracted in 2019 when it was revealed that the then director of the school, Simon Head, earned 410 thousand euros annually, with additional extras for housing and travel.

ISD offers After School Activities (ASA) for students from Reception (age 4) through Grade 12, as well as for parents and staff.

Activities include art, ballet, badminton, chess, drama, fencing, golf, hip hop, languages, robotics, table tennis, and the Duke of Edinburgh Award[29][30] The ISD Model United Nations Team participates in The Hague Model United Nations (THIMUN) Conferences.
