IB Results in Singapore
Singapore IB Diploma schools ranked by published average. International tier clears 33 to 39; MOE-stream tops 41. Global average is 30.32.
The brief
- Singapore is the world's strongest IB market. The 2024 global Diploma average was 30.32. Every Singapore school with a published recent figure clears it; top international schools clear it by six to ten points.
- The highest international-stream averages sit at Tanglin Trust (39.6, 2025), Dulwich Singapore (37.1, 2025) and NLCS Singapore (36.7, 2025).
- MOE-stream schools sit higher still. ACS (Independent) posted 41.2 in 2024 and 41.6 in 2023. Hwa Chong International posted 38.3 in 2025. Fee tier and admission quota differ from the international stream.
- The reference school is UWCSEA. Both Dover and East campuses posted 36.4 in 2025 with a 98.7% pass rate. UWCSEA is one of the longest-running IB Diploma schools in Asia.
- The MOE caveat matters. Local-stream IB schools cap foreign-passport intake and tier fees by nationality. The CPE-registered international wings (Hwa Chong International, SJI International, ACS International) carry a single fee tier and no quota.
Singapore runs more IB Diploma schools at high averages than any other city in the world. More than twenty schools deliver the Diploma to age eighteen with published recent results. The published averages divide into three bands. MOE-stream local schools sit at 41 to 42. International-stream flagships cluster between 36 and 40, with Tanglin's 39.6 the strongest published international-school result. A wide mid-tier posts 33 to 36, still three to six points above the global benchmark.

| 17 | One World International | 33 | 2025 | 100% pass; top score 40; 25% scored 35+. |
ISS International publishes a result distribution rather than a headline average. Its 2025 cohort posted a 94% Diploma award rate, 88% bilingual diploma and a top score of 43. The school is the oldest IB continuum school in Singapore and one of the smallest, around 450 students across ages 4 to 19.
St Francis Methodist posted 37.8 from its first IB DP cohort in 2021, with 100% scoring 30+ and 80% scoring 35+. No more recent published average; treat the 2021 figure as historic until the school publishes a fresh year.
Ranked by published DP average, MOE-stream and local hybrid
Three Singapore local schools run the IB Diploma alongside or in place of the GCE A-Level, governed by the Ministry of Education rather than the Committee for Private Education. They post some of the strongest IB averages in the world.
| Rank | School | Latest avg | Year | Notes |
|---|---|---|---|---|
| 1 | ACS (Independent) | 41.2 | 2024 | 41.6 in 2023. Boys-only to Year 4, co-ed for the Diploma years. MOE-governed. |
| 2 | Hwa Chong International | 38.3 | 2025 | CPE-registered international wing of Hwa Chong Institution. 46% scored 40+. |
| 3 | ACS International | 36.1 | 2023 | CPE-registered international school using the ACS name; operates separately from ACS (Independent). 96.5% pass; top score 45. |
| 4 | SFA Eduhearts International | 34.2 | 2024 | Full continuum with MYP authorisation since 2019 and DP since 2020. Strong SEN integration. |
SJI International runs IGCSE in Years 9 and 10 followed by the IB Diploma in Years 11 and 12. The school does not consistently publish a headline cohort average; verify the current figure with admissions.

How to read these numbers
An IB Diploma score compares like with like. Every IB candidate sits the same exams, marked by the same examiners, against the same criteria. A 36 in Tampines means what a 36 in London means.
The headline average still hides three things.
Cohort size. A 44 from a graduating cohort of fewer than twenty is not the same data point as a 39.6 from a cohort of two hundred. Variance shrinks as cohort size grows. Westbourne's 44 is the city's headline number, but it sits on a school of around thirty students total; Tanglin's 39.6 sits on one of the larger international IB cohorts in Asia.
Selection. Schools that filter into the Diploma via IGCSE thresholds or internal predictions post higher averages than schools that take all comers. Dulwich, Tanglin and ACS (Independent) all run selective sixth forms. Dover Court is non-selective and still posted 36 with a 100% pass rate, which is a different and arguably harder achievement than a 37 from a tightly filtered cohort.
The bilingual diploma rate. NLCS Singapore awards it to 65% of its cohort, Australian International to 41%, Overseas Family School and Canadian International to around 29%. The bilingual diploma requires Diploma-level work in two languages and one of TOK or the Extended Essay in a second language. The rate is harder to game than the headline number.
The MOE-stream caveat
Three local schools, ACS (Independent), Hwa Chong Institution and SJI, run the IB Diploma at the top of the global range under Ministry of Education governance rather than CPE registration. Two constraints apply for an arriving expat family.
Fee gating. Singapore citizens pay subsidised local fees; permanent residents pay higher fees, still well below international rates; international students pay full international rates, typically higher than the citizen rate but often still lower than the equivalent international school.
Quota gating. Singapore caps the proportion of foreign students at MOE-funded schools. Entry is competitive and sometimes restricted to specific year groups.
The CPE-registered international wings sit alongside the MOE-funded schools and carry the same brand without the quota or fee gating. Hwa Chong International, SJI International and ACS International are the three. The Diploma average sits a few points below the MOE-stream parent in each case.
Schools with no public DP results
Several Singapore IB schools either run too new a programme to publish a meaningful average, or do not publish one at all.
- SJI International runs IGCSE then IB DP at sixth form, with no consistently published cohort average. Recent cohorts have been strong; the school shares results with prospective families on request.
- Brighton College Singapore, founded 2020, has not yet published a complete cohort of IB or A-Level results.
- The PYP-only primary schools at Etonhouse and similar early-years operators are out of scope for this list.
- A few smaller IB schools share results in narrative form during admissions interviews but do not publish a headline figure on their website.
A school that runs the Diploma but does not publish results will usually share them when asked directly during admissions. Published data on a website is a commitment. A figure shared in a meeting is not.

FAQs
Which Singapore school has the highest published IB Diploma average?
Among MOE-stream schools, ACS (Independent) at 41.2 in 2024 and 41.6 in 2023 is the strongest. Among CPE-registered international schools, Tanglin Trust at 39.6 in 2025 leads, with Hwa Chong International (38.3, 2025), Dulwich Singapore (37.1, 2025) and NLCS Singapore (36.7, 2025) close behind. Westbourne College published a 44 in 2024 on a very small cohort; treat as indicative, not comparable.
How does Singapore compare to the global IB Diploma average?
The 2024 global Diploma average was 30.32. Every Singapore school with a recent published average comes in above it. International-stream schools cluster between 33 and 40; MOE-stream schools cluster between 38 and 42. Singapore sits structurally above the global mean at every tier.
Can my child do the IB at a local Singapore school?
Yes in principle, at ACS (Independent), Hwa Chong and SJI. Two constraints apply. Fee gating: international students pay full international rates, higher than the citizen and permanent-resident tiers but often still lower than the equivalent international school. Quota gating: foreign-passport admission is capped at MOE-funded schools and is competitive. The CPE-registered international wings (Hwa Chong International, SJI International, ACS International) avoid both constraints and post averages a few points below the MOE-stream parent.
Does a full PYP and MYP continuum produce better IB Diploma results?
Not directly. The structural argument is that PYP and MYP build the inquiry, research and writing habits the Diploma demands. The counter-argument is that British-style preparation through IGCSE produces equally well-prepared Diploma candidates. The Singapore data supports both readings. Tanglin's 39.6 sits on British-style middle years and IGCSE. UWCSEA's 36.4 sits on a full continuum. Dulwich's 37.1 sits on IGCSE. The continuum is a coherent IB experience, not a guaranteed scoring advantage.
What is a bilingual IB Diploma?
Diploma-level work in two languages, including completion of one of TOK or the Extended Essay in a second language. NLCS Singapore awards it to 65% of its cohort; Australian International to 41%; Overseas Family School and Canadian International to around 29%; Chatsworth and Hwa Chong International carry strong rates too. Universities treat it as a marker of academic bilingualism rather than a language certificate.
Why does Tanglin's 39.6 sit higher than UWCSEA's 36.4 if UWCSEA is the longer-running IB school?
The averages reflect different cohorts under different sixth-form structures. Tanglin runs IB and A-Level in parallel; families choose at the end of Year 11, which produces a self-selecting Diploma cohort. UWCSEA is IB-only across the school; every student in the graduating year sits the Diploma, so the average covers the full cohort. Reading the two figures together gives more than either alone.
