 In 1986, the school’s name was changed to the International School of Düsseldorf, and the stated mission was to prepare and encourage individuals to explore and use their potential and contribute to international understanding.In the 1990s ISD attained German Ersatzschule status, allowing the school to cooperate more closely with German educational experts on curricula, and paving the way for German students to transfer more easily between international and local educational systems.In 2001, ISD applied to the International Baccalaureate Organization (IBO) for authorization to introduce the Primary Years Program (PYP) and Middle Years Program (MYP), to allow for one continuous strand of instruction from early childhood to graduation.
