[5] SAS offers classes in the standard academic subjects as well as foreign languages, music, art, physical education, dance, sports, and technology.

Facilities include gyms, cafeterias, libraries, and theatres, as well as courtyards, playgrounds, playing fields, swimming pools, tennis courts, a rainforest, and an eco-garden.

In the beginning, around a hundred elementary and junior-high students attended classes in a colonial house on Rochalie Drive, on the edge of downtown Singapore.

[9] Over the next half-century, the school moved several times: By the late 1980s, SAS again faced space constraints, as enrolment continued to outstrip capacity at both the King's Road and Ulu Pandan campuses.

In addition, the Ulu Pandan lease would soon expire, and the Singapore government wanted the school to accommodate more students, as part of its push to attract foreign talent to help develop new industries.

To the surprise of many in the American community, enrolment quickly rose to capacity, and the western end of the campus had to be redeveloped into a new high school and early learning centre, which opened in 2004.

All members are invited to the annual general meeting (AGM) in October, at which the superintendent reviews the school's progress and finances.

[16] Besides spending time in their individual classrooms, students have two recesses every day, which take place on the two ELC playgrounds and in the large central hall.

Art, music, and PE classes occur in a three-day rotational schedule, with library, science laboratory, technology, and counselling lessons at longer intervals.

Destinations include the Singapore Zoo, Little India, the Asian Civilisations Museum, Sungei Buloh Wetlands Reserve, and various plays and theatre offerings.

The elementary school occupies the eastern end of the SAS campus, and includes its own language, art, music, and science classrooms, as well as a library, an auditorium/theatre, two pools, two gyms (one with a climbing wall), two cafeterias, and several playgrounds.

[19] The SAS middle school offers a foundation of academic classes complemented by elective courses and after-school activities.

These smaller groups within the large middle school are intended to help meet students’ social, emotional, and academic needs.

"Classroom Without Walls" takes each grade level to a regional destination for several days in the first month of school, and students develop relationships with peers and staff.

The “international perspective” central to the school's mission statement is reflected in academic offerings, service opportunities, and extracurricular activities.

SAS has identified seven critical skills it believes students need to be prepared for academic, professional, and interpersonal success in the twenty-first century.

These seven "desired student learning outcomes," or DSLOs, include content knowledge, cultural competence, character, collaboration, communication, critical thinking, and creativity.

Of the class of 2017, 89% went directly on to college or university, with 8% completing Singapore's National Service requirement (applicable to male Singaporean citizens or permanent residents) and 3% taking a gap year.

Younger students may participate in after-school sports through the Elementary Activities and Athletics (EAA) program, which offers weekday, pay-as-you-go classes such as soccer, baseball, and karate.

[32] Clubs and intramural teams offer climbing, ultimate frisbee, soccer, lacrosse, table-tennis, dodgeball, basketball, volleyball, and cricket.

[43] SAS high school students participate in Model United Nations and compete in a variety of math competitions as well as Knowledge Bowl and Academic Quiz Club.

Students compete in debate and forensics in the annual IASAS Cultural Conventions, which also include dance, drama, art and music.

Middle school students support causes they learn about in social studies and science classes, and also design independent service projects.

Sustainability measures include a large photovoltaic array, the conversion of a formerly air-conditioned cafeteria to an open-air space, enhancements to the school's rain forest and eco-garden, and the installation of low-flow faucets, more efficient chillers, and "green walls.

Food provider Hoe Brothers Catering has been working with all the school's sections since the 1960s,[53] and alumni remember signature dishes with fondness.

Healthy changes include increasing amounts of fruits, vegetables, and whole grains in meals, using healthier oils and less sugar and salt, and eliminating sodas and sugary drinks from campus.

The PTA organises classroom holiday parties, field trip chaperones, and special community events such as the Open House Ice Cream Social, the International Fair, and informative parent coffees.

It started in 1985 to support student athletic teams, and quickly expanded its mission to include boosting school spirit and promoting teamwork and sportsmanship.

Funds raised by the Boosters are used to support student clubs, productions, and teams, recognise academic achievements, and provide scholarships.

School facilities include air-conditioned classrooms and purpose-designed spaces for science, language, music, drama, dance, art and cooking classes.
