Singapore American School (SAS) is a non-profit, independent, co-educational day school located in the Woodlands area of Singapore. SAS offers an American-based curriculum for students in preschool through high school. One of Singapore’s first international schools, SAS was founded in 1956, and started with a hundred students in a colonial house. It has since developed into a school of nearly 4,000 students on a 36-acre campus, the largest American-curriculum school outside the United States. It is also the largest single-campus international school in the world. SAS is accredited by the US-based Western Association of Schools and Colleges (WASC). Students at SAS hold passports from around fifty different countries, with approximately two-thirds of them being United States citizens. Few Singaporean students attend the school as Singapore government regulations prevent most local students from attending international schools within the country. The majority of the teachers come from the US, and staff members from over twenty other countries also work at SAS. Most are hired overseas, and three-quarters hold master’s or doctorate degrees. The maximum number of students per class in the Early Learning Center (ELC) is 16, while for grades K through 12 it is 22. Beyond the standard academic subjects, SAS also offers classes in foreign languages, music, art, physical education, dance, sports, and technology. SAS was one of the first international schools to offer the AP Capstone program in 2014-15, and annually offers around 30 AP courses. Frequent field trips and community service opportunities link students to their host country, as do social studies and history units focussing on Singapore and Southeast Asia. The campus has both air-conditioned and open-air spaces, and has received received awards for its environmental efforts and huge solar panel array. In addition to classrooms, students have access to gyms, cafeterias, libraries and theaters, as well as courtyards, playgrounds, playing fields, a rainforest, and an eco-garden.
