For expat families, choosing the right international school in Singapore is a top priority. Singapore is consistently ranked among the world's best education systems and is home to one of Asia's richest concentrations of international schools. Whether you are relocating for work or making Singapore a long-term home, this 2026 guide covers the curricula available, the top client schools on International School Advisor, realistic fee expectations, and practical admissions advice to help your family settle smoothly.
Why Singapore Is a Top Destination for Expat Education
Singapore's education landscape is exceptional by any measure. The city-state consistently ranks at or near the top of international assessments like PISA, and its international school sector matches that quality with institutions representing virtually every major English-language curriculum. The country's political stability, low crime rate, and world-class infrastructure make it one of the most reassuring destinations for families relocating across borders. Singapore's multicultural society also means children quickly find peers from diverse backgrounds, easing the social transition that often concerns expat parents most.
Available Curricula in Singapore
International families in Singapore have an exceptional range of curricula to choose from. The International Baccalaureate (IB) is widely available, with many schools offering the full continuum from the Primary Years Programme through the Diploma Programme. The Canadian curriculum is strongly represented, notably at Canadian International School, which awards the Ontario Secondary School Diploma. British curriculum schools providing IGCSEs and A-Levels are numerous, as are American curriculum schools with AP programmes. For Indian expat families, CBSE and IGCSE pathways are available at several strong schools. This depth of options means families can typically continue the same curriculum their children were already following in their home country.
Top International Schools in Singapore for 2026
Below are four ISA client schools currently active on International School Advisor, each bringing a distinctive approach to international education in Singapore.
Canadian International School
One of Singapore's most established international schools, Canadian International School (CIS) operates across two campuses in Lakeside and Tanjong Katong. CIS follows the Ontario curriculum from Early Childhood through Grade 12, leading to the Ontario Secondary School Diploma recognised by universities worldwide. The school serves over 3,000 students and has a particularly strong sports and arts programme. For families from Canada or those seeking a curriculum that transitions seamlessly to North American universities, CIS is a natural first choice.
St. Joseph's Institution International
St. Joseph's Institution International is a Catholic co-educational school offering the IB Middle Years Programme and IB Diploma Programme for secondary students, plus the Cambridge Primary Programme for younger children. Located in Buona Vista, the school has a strong academic reputation and a values-driven ethos rooted in its Lasallian tradition. It draws students from across Asia and beyond and consistently achieves strong IB results. For families who value both academic rigour and character formation, SJI International is a compelling option.
One World International School
One World International School (OWIS) has grown rapidly in recent years and now operates across multiple Singapore campuses including Nanyang, Simpang Bedok, and Punggol. OWIS offers the IB Primary Years Programme alongside Cambridge IGCSE and A-Level pathways, giving families a clear academic track through secondary. The school is known for its inclusive environment, strong pastoral care, and competitive fees relative to other Singapore international schools — making it popular among families seeking quality education at a more accessible price point.
Global Indian International School Singapore
Global Indian International School (GIIS) Singapore is one of Asia's largest international school networks, with multiple Singapore campuses including a flagship Smart Campus in Punggol. GIIS offers CBSE, IGCSE, and IB curricula, making it particularly versatile for families who may relocate again within Asia. The school has a strong STEM focus and extensive extracurricular offerings. For Indian expat families in particular, the cultural familiarity and CBSE curriculum continuity make GIIS a popular and practical choice.
School Fees in Singapore
International school fees in Singapore are among the highest in Asia, reflecting both the quality of provision and the cost of operating in one of the world's most expensive cities. For 2026, annual tuition for primary school students runs from approximately SGD 20,000 to SGD 38,000, with secondary fees typically ranging from SGD 28,000 to SGD 48,000. Some premium schools charge considerably more. Many multinational employers in Singapore provide school fee allowances as part of expat packages, which can significantly offset these costs. Families should also budget for a one-time registration or capital levy, which at some schools can reach SGD 2,000–6,000 or more.
Practical Admissions Tips for Singapore
Singapore's most popular international schools regularly operate at or near capacity. Waiting lists for certain year groups at sought-after schools can stretch twelve to eighteen months. Starting your research and applications early — ideally as soon as you know your relocation date — is strongly advisable.
The Singapore academic year runs from January to December for most international schools, split into four terms. Some schools follow an August to June calendar, so confirm the calendar of any school you are considering to plan your family's arrival accordingly.
Location is an important factor. Schools are spread across the island, from Orchard Road and Buona Vista in central zones to newer campuses in Punggol, Tampines, and Jurong. Many families choose their home location based on proximity to their selected school, so narrowing down your shortlist before signing a lease is wise.
Singapore requires all children of school age to attend school, and the Ministry of Education has specific rules regarding school placement for dependent pass holders. International schools are the standard route for expat children, but confirm your child's pass type and eligibility during the admissions process.
