[Education] Top 3 American International Schools in Singapore

Choosing the right school is often the biggest concern for parents moving to Singapore. For those aiming for U.S. universities or a more liberal learning environment, American international schools are usually at the top of the list. However, with varying fees and curricula, making a choice can be challenging. Here is a detailed comparison of the three most prominent American-style international schools in Singapore.

At a Glance

SAS: The gold standard for U.S. college prep with a massive campus and extensive AP courses.

SAIS: Flexibility to choose between IB and AP, featuring state-of-the-art facilities.

ISS: A warm, small-scale community focused on IB expertise.

1. Singapore American School (SAS): The Pride of American Education

When people think of an "American school" in Singapore, SAS is usually the first name mentioned. Established in 1956, this historic institution offers an environment that feels like a top-tier school in the United States. With over 45 Advanced Placement (AP) courses, it is the premier choice for students targeting elite U.S. universities.

Curriculum: American Curriculum and AP-focused
Fees (2025-2026): Approx. SGD 40,870 per year for High School (approx. 46.51 million KRW)
Facilities & Environment: The campus is currently undergoing a massive renewal project called "SAS Reimagined." Note that it is located in Woodlands (North), which is quite a distance from the city center.
Admissions Tip: Priority is given to U.S. citizens and children of U.S. corporate employees, leading to long waitlists. It is recommended to apply at least 6 months to a year in advance.

2. Stamford American International School (SAIS): The Leader in Curricular Flexibility

While relatively newer, SAIS has become a favorite among international parents due to its cutting-edge facilities and flexible academic paths. Its biggest advantage is allowing high school students to choose between the IB Diploma and AP courses based on their strengths—a huge benefit for students still exploring their career paths.

Curriculum: Offers both IB (PYP, MYP, DP) and AP courses
Fees (2025-2026): Approx. SGD 52,250 per year for Grades 9–12 (approx. 59.46 million KRW)
Location & Facilities: Located at Woodleigh with excellent accessibility. It features specialized facilities like an Innovation Center and a Golf Academy.
Note: Their EAL (English as an Additional Language) program is highly structured, though it can cost an additional SGD 6,900 to 13,000 per year.

3. ISS International School (ISS): An IB Specialist with a Family Atmosphere

If you prefer a nurturing environment over a massive campus, ISS might be the right fit. Originally founded as an American school, it now operates as a pure IB school known for its tight-knit community, often referred to as the "Kampong Spirit."

Curriculum: Full IB Continuum (PYP, MYP, DP)
Fees (2025-2026): Approx. SGD 54,430 per year for Grade 12 (approx. 61.94 million KRW)
Features: Small class sizes allow teachers to understand each child's unique traits. Many students who find large schools overwhelming tend to regain their confidence here.
Location: Situated in the Alexandra area, making it very convenient for those living near the city center.

Essential Practical Tips

Check EAL Costs: If English is not the student's first language, EAL fees can be significant. Ensure you include this in your budget.
Vaccination Requirements: Children under 12 must obtain a vaccination certificate for Measles and Diphtheria via the Singapore Ministry of Health (HPB) to secure a Student Pass (STP). It is easier to prepare these documents before leaving your home country.
Commute vs. Housing: For SAS, unless you live in the Woodlands area, the school bus ride can take over 1.5 hours round-trip. It is standard practice to choose the school first, then find a home nearby.
Calculate Hidden Costs: Beyond tuition, expect to spend an additional SGD 5,000 to 8,000 annually on facility fees, registration fees, uniforms, and school bus services.
