At its peak, TAS was the largest American school outside the United States with about 2,000 students. The school closed due to disruptions that developed into the Revolution. The last superintendent, i.e., principal of the entire school, Dr. William Keough, was seized the hostage crisis in 1979 in the course of shipping out the students’ transcripts; the transcripts were never sent. The TAS campus is now part of university.
