SIS was founded in 1971 with the assistance of the United States Consulate in Surabaya, and the first group of students numbered only 14. Several campus sites have been occupied in its fairly brief history, but the current campus was opened in August of 1995. The campus has two computer labs, three science labs, gym, 50-meter swimming pool, soccer field, music and art rooms, and over 40 classrooms. The campus was designed to hold approximately 700 students. SIS students come from all over the world, and have a variety of educational backgrounds and interests.
