The 5 best IB schools in Singapore are challenging yet rewarding!
Graduating from an international school in Singapore taught me two things: sleep is optional, and critical thinking is forever. Those Theory of Knowledge essays and endless CAS hours built grit I didn’t even realise I had until life threw me another group project!
If you’re thinking of sending your kid down the same caffeine-fueled yet deeply rewarding path, rest assured, there are top IB schools in Singapore worth considering. Here are some of the best ones that meet our criteria.
How much do IB schools cost in Singapore?
International Baccalaureate schools in Singapore typically cost S$25,000 to S$55,000 per year, depending on the school and grade level. Fees usually include tuition only, while application, building, and activity fees are charged separately.
1. Anglo-Chinese School Independent
Address: 121 Dover Road
Contact: +6567731633
Hours: Monday to Friday, 7.30 AM–6 PM
My niece goes to Anglo-Chinese School (Independent), and honestly, it’s one of the toughest yet most well-rounded IB schools in Singapore.
The school’s IB Diploma Programme is legendary; it consistently ranks among the top globally, with average scores around 41 points and multiple perfect scorers each year.
Their focus isn’t just on grades, though. ACSI runs strong service and leadership programs rooted in its Methodist values. Students are heavily involved in CAS projects, sports, and co-curricular activities that build discipline and empathy.
The facilities match the rigour, too: think modern labs, sports complexes, and music halls designed to push both the mind and body. And for a local school, ACSI’s international exposure through exchange programs and Model UN is impressive.
That said, it’s high-pressure and highly selective, which might not be ideal for students who struggle with stress or competition. Admissions are tight, as well, with sky-high expectations, so success here comes with intensity, not ease.
Has a strong common family identity
This school is great. It has a strong sense of family identity, a holistic education, air-conditioned classrooms, and a canteen.

2. Chatsworth International School
Address: 72 Bukit Tinggi Road
Contact: +6564633201
Hours: Monday to Friday, 8.30 AM–5 PM
Chatsworth International School showed up a lot when I was comparing IB schools, primarily because it’s one of the few in Singapore that offers the full IB pathway from Primary Years through Middle Years to the Diploma, all in one campus.
It’s not just all marketing, either. The school won “Best IB School in Singapore” from WhichSchoolAdvisor in 2022, and again in 2024, and was recognised with Gold for IB curriculum at the Singapore Education Awards in 2023 and 2024.
Academically, the numbers are steady and transparent, not inflated. The class of 2025 posted a 100% IB Diploma pass rate with an average score of 34.3 points (above the global 30.6 average). Their Year 11s in the MYP eAssessment hit a 100% pass rate with scores well above world averages, as well.
These figures matter because Chatsworth is one of the few schools here that actually makes MYP students sit the full external assessment, instead of coasting into IB.
Moreover, the Bukit Timah campus sits next to nature, with arts, sports, and maker spaces built into it, plus theatre festivals and competitive sports.
From a parent-research angle, the scale and access are also impressive. Class size averages around 18 students, with fees sitting in the S$33K to S$44K/year range (noticeably lower than the ultra-premium campuses).
Now for the trade-off: the IB average (mid-30s) is solid and above world average, but it’s not the extreme over-40 point profile seen at other academically selective IB schools.
My son is very happy and enthusiastic to go to school
Very nice school.. all teachers and staff are very friendly.. a lot of outdoor activities, my son is very happy and enthusiastic to go to school every morning.

3. North London Collegiate School
Address: 130 Depot Road
Contact: +6569893000
Hours: Monday to Friday, 7.30 AM–5 PM
North London Collegiate School in Singapore stands out as one of the most academically ambitious IB schools I’ve researched. It’s the Singapore branch of the prestigious NLCS in the UK, a school with over 170 years of history and a track record of top IB results worldwide.
Here, students follow the full IB continuum from Primary Years through to the Diploma Programme, guided by the teachers trained in the NLCS London model of “deep scholarship.” The curriculum focuses on stretching students beyond exams, with enrichment programs in philosophy, debate, and research.
Its IB Diploma results are among the strongest in the region, with an average of 39.2 points in 2024, and multiple perfect scorers. NLCS Singapore was also named “Best Emerging School in Asia” in 2023 by the Singapore Education Awards.
I also noted how its facilities match the academics. It has a state-of-the-art campus on Depot Road, with science labs, black box theatres, and sports halls that rival university setups. There’s also a strong pastoral program and leadership focus through house systems that mirror British independent school traditions.
However, fees are among the highest in Singapore (up to S$55K yearly), and the academic intensity isn’t for everyone. Some parents I interviewed also noted that the school is still relatively new (established in 2020), so networks and alumni roots aren’t as deep yet.
Diversity is celebrated, and students from various backgrounds feel valued
My son has been studying in this school for the past 4.5 years, and he loves the school. Kids are given a lot of exposure in terms of art, music, and dance according to their likes and interests. All the teachers in the school are very responsive. What truly stands out is the school’s welcoming, inclusive atmosphere, where diversity is celebrated, and students from various backgrounds feel valued and respected.

4. Dulwich College
Address: 71 Bukit Batok West Ave. 8
Contact: +6568901000
Hours: Monday to Friday, 8 AM–5 PM
Dulwich College in Singapore is one of the most established British-founded IB schools in the city, and it shows in both pedigree and performance.
It opened in 2014 as part of the Dulwich College International network, which includes campuses in London, Shanghai, and Beijing (all known for strong IB results and university placements).
The school offers the full IB continuum (PYP-MYP-DP) under the “One College” philosophy, ensuring academic consistency from early years to graduation.
Its IB Diploma students consistently post average scores of around 37–39 points, with several achieving perfect 45s each year. It’s also known for a balanced education model that values arts, sports, and service as much as grades.
The campus in Bukit Batok is massive, with a performing arts centre, Olympic-sized pool, and dedicated STEAM labs, making it one of the country’s most well-equipped schools.
However, Dulwich College fees are on the higher side (S$45K to S$50K annually) and admissions are competitive, especially for the upper years. For quieter students and those who thrive in more intimate environments, the school’s large size can be intimidating.
Dulwich is setting my girls up for the future!
I love Dulwich. My two daughters are thriving here. From academics to sports, music, performances, trips and more, Dulwich is setting my girls up for the future! Highly recommended.

5. One World International School
Address: 21 Jurong West Street 81
Contact: +6569146700
Hours:
Monday to Friday, 8 AM–4.30 PM
Saturday, 9 AM–1 PM
One World International School (OWIS) has become a strong contender among Singapore’s IB schools for families seeking quality education without sky-high fees.
It offers the IB Primary Years Programme (PYP) and IB Diploma Programme (DP) alongside Cambridge IGCSEs, so students have both global flexibility and academic breadth.
The school is known for its diverse student body, with over 70 nationalities and a policy that caps any single nationality at 30%. This ensures genuine multicultural exposure not just in brochures, but in daily classroom life.
The Nanyang campus features open learning spaces, STEAM facilities, and strong pastoral care systems. OWIS has earned praise from parents for its community-driven atmosphere, teacher engagement, and accessible leadership team.
With average class sizes under 24 and transparent fees (roughly S$20K to S$27K yearly), it delivers value that many larger schools can’t match.
That said, the IB Diploma track is relatively new, so long-term academic data is still building.
Excellent STEM and robotics programs
Excellent STEM and robotics programs have sparked my child’s interest in technology and innovation.
