Singapore American School

The Singapore American School (abbreviation: SAS) is a private school in Singapore. Established in 1956, the school offers an American-based curriculum from preschool through to Grade 12 for approximately 3,800 expatriate students, making it the largest international school in the world. Approximately two-thirds of the students at SAS are United States citizens, with the rest of the student body comprising more than 50 nationalities. Few Singaporean students attend the school as Singapore government regulations prevent most local students from attending international schools within the country.

Academically, SAS has the largest number of high school students enrolled in Advanced Placement Program (AP) courses of any international school in the world, delivering 29 AP courses as an integral part of high school course options.

SAS has a strong athletic tradition. It is part of the Interscholastic Association of Southeast Asian Schools (IASAS), providing SAS students with the opportunity to compete regularly with other international schools in the region in both academic and sports events. Such competitions and conventions include Model United Nations, the arts, and a host of sports such as swimming, cross country, and basketball. The school has a student newspaper, The Eye, which has won the Columbia Gold Crown award multiple times, as well as other rewards from the National Scholastic Press Association.

SAS is accredited by the Western Association of Schools and Colleges (WASC) in the United States.

The Good Schools Guide International reviewed the school as "an extremely spacious school for Singapore with wonderful, modern facilities, strong academics, and a plethora of options within the curriculum and extracurricular program".
