Established in 1948, ISP is both the oldest and largest international school in the Czech Republic, with over 844 students representing more than 60 nationalities.

ISP offers its 11th and 12th grade students the opportunity to take the International Baccalaureate Diploma Program.

According to Czech tax law, ISP has only one shareholder, The International School of Prague Foundation, a US 501(c) organization.

Finally, in 1996, all classes were brought together on the current, custom-built campus in the village of Nebušice, in the Šárka valley, part of the Prague 6 district.

Ten years later, in celebration of its 60th anniversary, ISP underwent a 6.5 million euro renovation of the current campus.
