How many American schools in Singapore
Singapore's American curriculum cluster sits at 6 schools running a US-style high school curriculum, with several other schools offering the US high school diploma as a parallel option alongside IB or the British system. The category is smaller than Hong Kong's or Tokyo's American sectors but the two anchor campuses, Singapore American School in Woodlands and Stamford American International School in Woodleigh, are among the largest international schools in Asia by enrolment.
Singapore American School is the historical anchor of the US expat community in Singapore, founded in 1956 and now enrolling around 4,000 students from preschool through grade 12. Stamford American opened in 2009 and has grown to roughly 3,000 students. Both schools run AP and IB Diploma in parallel, allowing students to pick the qualification that best fits their university plan. Singapore American also offers a regular US high school diploma without external examinations for students who do not need AP or IB. For the curriculum primer see our American curriculum page.
The smaller providers, including Overseas Family School in Pasir Ris, ISS International School in Preston Road and Hillside World Academy in Bukit Timah, offer the US high school diploma alongside IB. These schools serve families who want US-style high school structure with smaller class sizes than Singapore American or Stamford American can offer.
Fees and the AP or IB choice
American school fees in Singapore are among the highest in the world. Annual high school tuition ranges from S$32,000 at the smaller providers to S$48,500 at Singapore American School and Stamford American. The median is around S$42,000 in 2026. Sixth form tuition typically carries a 5 to 10 percent uplift on Year 11 equivalent. Capital fees of S$3,500 to S$5,500 are billed annually. AP exam fees run S$200 to S$280 each, with most students taking 4 to 6 AP exams over grades 11 and 12.
The AP or IB choice matters for the university application. AP is a subject-by-subject qualification; IB is a structured six-subject diploma. Students applying primarily to US universities often prefer AP because they can choose breadth of subjects. Students applying to UK or European universities lean towards IB because the points score maps cleanly to UCAS conversions. Singapore American and Stamford American offer both, which removes the need to choose at age 14. See our Singapore fees guide for the loading mathematics.

Illustrative example schools
The five schools below are illustrative, not a ranking. Each holds WASC accreditation and reports verified university outcomes.
Singapore American School in Woodlands is the largest international school in Singapore. AP, IB Diploma and the US high school diploma run in parallel. WASC accredited. Deep university advisory service for US, UK and Canadian applications. Strong athletics programme and large alumni network.
Stamford American International School in Woodleigh runs the full continuum from preschool to grade 12, offering AP and IB Diploma alongside the US high school diploma. The largest IB World School in Singapore by single-campus enrolment.
Overseas Family School in Pasir Ris is a smaller, more affordable American-pathway provider running the US high school diploma and IB. Strong reputation among families on shorter Singapore postings looking for predictable structure.
Hillside World Academy in Bukit Timah delivers the IB Diploma alongside a US high school diploma, with bilingual English and Mandarin streams. A useful option for American families who want their child to come out of Singapore with strong Mandarin.
Where American families live
American families in Singapore concentrate in three zones, each shaped by school proximity. Woodlands, Sembawang and parts of Yishun for Singapore American School families who want short school runs. The Woodlands neighbourhood is lower density, more suburban, and has the largest US expat enclave in Singapore. Bishan, Ang Mo Kio and Bukit Timah for Stamford American Woodleigh and Hillside World Academy. East Coast and Pasir Ris for Overseas Family School. A smaller cluster of US executives live in Orchard Road apartments or on Sentosa, using school transport.
The American expat community in Singapore is anchored on Woodlands more than on any other neighbourhood, because Singapore American School has dominated the US-track market for seven decades. American Chamber of Commerce social life and family events sit around the school. See our Singapore relocation guide for the wider context, and use the cost calculator to model total relocation cost.
Admissions calendar
The Singapore international school year runs August to June. Applications for the August 2026 academic year opened at most American schools in August to October 2025. Singapore American School closed its main intake lists for the elementary grades and grade 6 in December 2025, with offers in February. Stamford American ran a similar cycle. Mid-tier schools accept applications on a rolling basis through to May, subject to grade level availability.
Grade 11 transfers after September are rare and usually involve restarting the AP or IB Diploma year. Grade 10 and 11 transfers during the IGCSE or pre-AP year are possible but require careful subject matching. WASC accreditation makes transcript transfer to US-based high schools smooth, which matters when families repatriate mid-year.
