11 Best IGCSE Schools in Singapore (October 2026)

Read the results column with care. Schools report different things: Tanglin, Dulwich and OWIS give a share of all grades, GIIS words its figure as a share of students, and AIS has only published its 2024 numbers. A selective school with a strong intake will post bigger numbers than a non-selective one that does more with a wider range of students, which is why I weigh Dover Court's figure for grades above target.

If you're working out where to study IGCSE in Singapore on a tighter budget, the value tier here is OWIS, SMMIS and St Francis Methodist School, all under S$31,000 a year on their published IGCSE school fees, plus PSB Academy for its short two-subject course.

Two exam boards set the IGCSE in Singapore. Cambridge IGCSE is the one most schools on this list use. Cambridge calls it the world's most popular international qualification for 14 to 16 year olds, offers more than 70 subjects, and aligns its standards with the GCSE taken in England. Most Cambridge IGCSEs are graded A* to G.

Pearson Edexcel International GCSEs are graded 9 to 1, the same scale as England's GCSEs, and come in 37 subjects. Pearson says they're equivalent grade for grade to UK GCSEs. Outside the UK, a school can take a linear route with exams at the end of two years, or a modular one with an exam after each unit.

Schools treat 9 to 7 as A* to A and 9 to 4 as A* to C, which is why the results in this guide mix the two scales. Both boards say universities around the world accept their IGCSEs. What matters more is the subject list a school offers and how it picks a board for each subject: Dulwich and Nexus mix boards, Insworld is all Edexcel, and most of the rest are Cambridge.

The local alternative is changing. According to SEAB, the GCE N(T), N(A) and O-Level certificates are combined and renamed as the Singapore-Cambridge Secondary Education Certificate (SEC) in 2027. Students sit each subject at G1, G2 or G3, which follow the grading of the N(T), N(A) and O-Level papers. It's the exam at the end of MOE's Full Subject-Based Banding, which replaced the Express and Normal streams from the 2024 Secondary 1 cohort.

The SEC, like the O-Level before it, is examined and awarded jointly by SEAB, MOE and Cambridge International Education, on Singapore's national syllabus. The IGCSE is Cambridge's or Pearson's international qualification, on an international syllabus. Both are sat at about 16. St Francis Methodist School is the one school here that teaches the O-Level and the IGCSE side by side, so it's a good place to ask how they compare.

If your child is new to Singapore and you'd rather move into a government school, the entry test is AEIS, and my AEIS preparation guide covers the centres that prepare for it.

If you're looking for an IGCSE school in Singapore, these are the things I'd check, roughly in this order.

• Results the school publishes itself. Ask for the share of grades at A* to A (9 to 7) and at A* to C (9 to 4), the year, and the cohort size. A school that only shows off its star students is telling you less. Dover Court's share of grades above each student's target is the kind of number I'd ask every school for.
• Which board, subject by subject. Cambridge or Pearson Edexcel, and for Edexcel, linear or modular.
• What comes after Year 11. A Levels, the IB Diploma, the HSC, WACE or a diploma. Changing school at 16 is disruptive, so pick a school whose Sixth Form you'd also choose. For the IB route, see my guide to the best IB schools in Singapore.
• The full fee, not the tuition line. Application, enrolment and building fees, exam fees, uniforms and devices. Dulwich adds S$10,000 in one-off fees for a new student, while OWIS includes uniforms and textbooks in its fee.
• Registration, for a private school. MOE's guidance on registering a school says a school offering full-time primary or secondary education on a foreign or international curriculum, or full-time preparatory courses for external exams, registers with SkillsFuture Singapore. SkillsFuture Singapore has since merged with Workforce Singapore into the Skills and Workforce Development Agency (SWDA).

Before you pay a deposit to a private school, look it up in the PEI Listing on TPGateway, the official register of private education institutions, which older guides call the CPE register. You can search by school or by course and filter by EduTrust status. Under the Private Education Act, a registered school can't run a course longer than one month full-time and 50 hours without SWDA's permission, so check that the IGCSE course itself is listed, not only the school.

I started from the schools that come up most when you search for IGCSE schools in Singapore, and from the longest lists that rank for the term, including directories that name more than 30 schools. Then, on 28 October 2026, I read each school's own 2026 results announcement and its 2026 or 2026-27 fee schedule. Where a school words its results differently, or hasn't published recent ones, I say so in the entry rather than guess.

I left out UWC South East Asia, where students sit IGCSE exams in Grade 10 but which doesn't publish an IGCSE grade breakdown I could find (it's in my international schools guide for its IB results). I also left out Brighton College (Singapore), whose results page shows Brighton College UK's GCSE results rather than Singapore's, and NPS International School, whose own results page only carried older figures. Several smaller schools on the directory lists had no published results or fees at all. I'll update this guide when the 2027 results are out.

An IGCSE school in Singapore costs from S$27,320 a year at St Francis Methodist School and S$27,774 at OWIS Nanyang up to S$57,540 for Year 11 at Dulwich College, on the 2026 and 2026-27 fee schedules each school publishes. Tanglin, Dulwich and Dover Court charge S$45,294 to S$57,540 a year.

Budget for one-off fees too: Dulwich charges a new student S$10,000 in application, enrolment and capital fees, and Nexus S$6,213. A short course is far cheaper. PSB Academy's two-subject IGCSE comes to S$5,241 with its mandatory fees.

No. Both are sat at about 16 and Cambridge is involved in both, but the GCE O-Level is Singapore's national exam, set with SEAB and MOE on the local syllabus, while the IGCSE is an international qualification from Cambridge or Pearson Edexcel. From 2027 the O-Level is folded into the new Singapore-Cambridge Secondary Education Certificate (SEC).

In the SEC, students take each subject at G1, G2 or G3, and G3 follows the O-Level grading. If you want to compare the two routes in one place, St Francis Methodist School teaches both.

Yes. The British Council in Singapore registers private candidates for both IGCSE boards, Cambridge International and Pearson Edexcel, through its online School Exams Registration System, and a registration isn't processed until the exam fees are paid. You prepare on your own or with a tutor, then sit the exams with the British Council.

Late entries carry a penalty fee, and any change to an entry has to be made in person at its Napier Road centre. If your teen wants help preparing, my guide to IB tuition in Singapore also covers IGCSE tutors. PSB Academy, for the record, doesn't take exam-only private candidates.

Three schools on this list let a student choose either after the IGCSE. Tanglin Trust School has about 130 Sixth Formers on A Levels and 70 on the IB Diploma, Dulwich College (Singapore) offers the IB Diploma or Pearson Edexcel International A Levels in STEM, and GIIS offers the IB Diploma or Cambridge AS and A Levels.

A Levels suit a student ready to narrow down to three or four subjects at 16. The IB keeps six subjects going, three at Higher Level and three at Standard Level, plus the Extended Essay and Theory of Knowledge. My guide to the best IB schools in Singapore compares the IB Diploma results.

Yes. MOE says private education institutions, international schools included, must get its approval before they admit a Singapore Citizen. You apply to the school, the school sends the documents to MOE if it's willing to offer a place, and MOE takes up to 4 weeks, or up to 8 for complex medical cases.

The privately funded schools don't need MOE approval. Dover Court's fee page says MOE processing typically takes six to eight weeks and that approval isn't guaranteed, so start early.
