Singapore's Best Schools 2026

In the 2022 admissions cycle, one Singaporean secondary school sent 48 students to the University of Cambridge, more than any other school anywhere in the world. That school, Raffles Institution, is the same institution founded by Stamford Raffles in 1823, making it, at 202 years old, the oldest school in the entire country. This guide ranks Singapore's genuinely top-performing schools using real PSLE cut-off data and results, and covers a genuinely significant, time-sensitive detail: 2026 marks the final year Singapore will ever run the O-Level exam in its current form, before a new Singapore-Cambridge SEC replaces it entirely.

How Singapore's School Rankings Actually Work

Singapore's Ministry of Education doesn't publish an official "best schools" ranking; what functions as the country's de facto ranking system is the PSLE Achievement Level cut-off point, the score of the last student admitted to a given school under the standard, non-affiliated admissions route. Lower is better: each of the four PSLE subjects is graded AL 1 to AL 8, and a student's total score across all four falls somewhere between AL 4 (a perfect score) and AL 32. Schools with a Cut-Off Point between AL 4 and AL 6 represent the most competitive tier in the entire country. It's worth understanding one further wrinkle before comparing schools directly: affiliated schools, those with a formal, decades-long relationship to a specific "feeder" primary school, admit affiliated students at PSLE scores 4 to 8 AL points looser than the open, non-affiliated bar, so the fairest comparison of a school's genuine competitiveness uses its non-affiliated cut-off, not the affiliated one.

1. Raffles Institution

Raffles Institution, founded in 1823, is Singapore's oldest school and its single most academically dominant, currently enrolling around 4,000 students under the Raffles Programme, a six-year Integrated Programme it has run jointly with sister school Raffles Girls' School since 2007, letting students bypass O-Levels entirely and proceed straight to A-Levels at the end of Year 6. RI's international outcomes are genuinely extraordinary: it has produced 96 Ivy League and Oxbridge admits in recent cycles and, in 2022, achieved the highest number of University of Cambridge admissions of any school anywhere in the world, 48 offers in a single cycle, alongside 52 Oxford acceptances the same year. Its PSLE cut-off consistently sits at the very top of the national range, AL 4 to 6.

2. Hwa Chong Institution

Hwa Chong, formed through a 2005 merger of The Chinese High School and Hwa Chong Junior College, operates under Singapore's Special Assistance Plan, cultivating a genuinely bilingual, bicultural Chinese-English academic environment alongside its Integrated Programme and Gifted Education Programme. HCI was among the very first schools in Singapore to offer the six-year IP pathway leading directly to A-Levels, and it consistently posts PSLE cut-offs of AL 4 to 7, placing it in the same elite tier as Raffles Institution nationally.

3. Raffles Girls' School

RGS, established in 1879, is one of Singapore's oldest schools and, alongside its brother institution Raffles Institution, jointly runs the six-year Raffles Programme. It was awarded the Ministry of Education's School Excellence Award in 2006 for exemplary school processes and practices, and its notable alumnae span an unusually broad range of fields. RGS remains part of the Gifted Education Programme's exclusive four-school secondary continuation, alongside Raffles Institution, Hwa Chong Institution, and Nanyang Girls' High School, meaning students identified as gifted at primary level gain automatic entry to these four schools specifically, regardless of PSLE score.

4. Nanyang Girls' High School

Nanyang Girls', an Integrated Programme school operating under the Special Assistance Plan, is one of only four secondary schools nationally continuing Singapore's Gifted Education Programme, and it consistently posts PSLE cut-offs in the AL 5 to 8 range, placing it firmly among the country's top handful of schools alongside Raffles and Hwa Chong.

5. Dunman High School

Dunman High, a strong Integrated Programme school with cut-offs typically in the AL 6 to 10 range, is consistently named among Singapore's leading secondary institutions, and it's one of the original schools selected to pilot the six-year IP pathway when it was first introduced nationally.

6. Anglo-Chinese School (Independent)

ACS(I), a co-educational Integrated Programme school with PSLE cut-offs typically between AL 7 and 12, is one of the more geographically and demographically prominent independent schools in the country, offering a genuinely broad co-curricular and academic profile within Singapore's competitive IP tier.

7. Victoria School

Victoria School, a popular boys' IP school with historical cut-offs around AL 8 to 12, was among the original founding schools selected for Singapore's Integrated Programme when it launched in 2004, alongside Raffles Institution, Hwa Chong, Nanyang Girls', Dunman High, and River Valley High.

8. Methodist Girls' School

Methodist Girls' School runs a genuinely popular Integrated Programme specifically for girls, sitting consistently within Singapore's competitive tier and frequently named alongside Raffles Girls' and Nanyang Girls' as one of the country's leading options for families of daughters seeking a strong, single-sex IP pathway.

9. Singapore Chinese Girls' School

SCGS sits within the competitive Express-stream tier, appealing specifically to families whose daughters are strong PSLE performers but for whom the very tightest IP cut-offs at Raffles or Hwa Chong-level schools aren't the deciding priority, offering a genuinely strong academic alternative within Singapore's broader Express pathway leading to the current O-Level exam.

10. Cedar Girls' Secondary School

Cedar Girls', a consistently popular autonomous school with cut-offs in the AL 10 to 14 range, represents the strong tier just below Singapore's most elite IP schools, and it's regularly cited as one of the country's most consistently in-demand autonomous secondary options for girls.

The Genuinely Big Story: 2026 Is the Last-Ever O-Level Cohort

This is a detail worth understanding directly if you're researching Singapore's school system right now, since it changes what "results" will even mean going forward: 2026 marks Singapore's final cohort to sit the Singapore-Cambridge GCE O-Level examination in its current, long-standing form. From the following intake, O-Levels are being replaced entirely by a new qualification, the Singapore-Cambridge Secondary Education Certificate (SEC), developed jointly by Singapore's Ministry of Education and Cambridge Assessment International Education. This is a genuinely significant structural shift for any family with a child currently in, or about to enter, Singapore's Express stream, the majority pathway most secondary schools in the country use, since Integrated Programme students at schools like Raffles Institution and Hwa Chong, who bypass O-Levels entirely for a direct route to A-Levels, are unaffected by this specific change. Families should confirm directly with their child's school exactly how the SEC transition affects their specific cohort's timeline and assessment structure, since implementation details are still being finalized at time of writing.

Integrated Programme vs. the Traditional O-Level Route

All ten schools on this list at the very top of the ranking offer the Integrated Programme, letting students skip O-Levels (or soon, the SEC) entirely for a six-year through-train straight to A-Levels, IB, or an equivalent school diploma. The majority of Singapore's roughly 147 secondary schools, however, remain Express-stream, leading to O-Levels at the end of Secondary 4, the pathway now transitioning to the new SEC. For families specifically weighing the Cambridge-affiliated qualifications Singapore's system produces, whether O-Level, the incoming SEC, or A-Level at the end of an IP track, our complete guide to Cambridge IGCSE is useful comparative context, since Singapore's O-Level and Cambridge's international IGCSE are related but distinct qualifications, both developed in partnership with Cambridge Assessment but calibrated slightly differently for their respective markets.

What Raffles Institution's Cambridge Numbers Actually Reveal

It's worth dwelling on Raffles Institution's genuinely remarkable Cambridge and Oxbridge placement record, since it reveals something structurally important about how Singapore's top IP schools actually operate: these institutions aren't simply strong by local PSLE and A-Level standards, they compete directly, and often win, against the world's most elite international schools for places at the world's most selective universities. A school producing more University of Cambridge admissions in a single cycle than any other school on the planet is a genuinely extraordinary outcome, and it reflects Singapore's broader national investment in academic rigor across its top institutions, not a fluke specific to one particularly strong cohort.

Supporting Students at Any of These Schools

Whether your child is navigating PSLE preparation to secure a place at one of Singapore's most competitive IP schools, working through the current O-Level system in its final cohort, or preparing for the incoming Singapore-Cambridge SEC, consistent, subject-specific academic support genuinely matters at every stage of this highly competitive system. If you're trying to work out whether your child needs that kind of targeted support right now, our article on spotting the early signs a child needs extra academic support is a useful starting point regardless of which stage of Singapore's system your child is currently navigating.
