A gift from the U.S. government in the form of a USAID grant in 2005 provided the necessary fiscal support to successfully expand the school, which was then re-chartered under the name ISK.

Former First Lady Laura Bush and former Secretary of State Condoleezza Rice had both taken a special interest in ISK during past visits to Kabul and met with administrative representatives of the school.

In addition to academics, ISK offered athletics and a full performing arts program to include music, drama, and dance.

ISK has also represented Afghanistan with the Model United Nations (MUN) program for the past four years at Georgetown University in Qatar.

As a result of this project twenty-nine ISK students were published in a book titled, "1000 Pencils: From Kinglake to Kabul."
