Tanglin Trust Retains Outstanding BSO Rating and Enters Spears Global Top 100
Singapore's oldest British school has been rated outstanding in every category for a consecutive BSO inspection cycle, while also securing a place among the world's top 100 private schools.
Tanglin Trust School has once again been awarded the highest possible grade across every category in its British Schools Overseas inspection, according to the school's published BSO report, which followed an inspection conducted in November 2025 by five Education Development Trust inspectors. The outcome makes Tanglin the only school in Singapore to hold a consecutive outstanding rating under the UK government-recognised framework.
Inspectors visited 122 lessons and held 51 meetings with leaders, teachers, pupils and parents. Their report praised the school's "exceptional curriculum" and "consistently outstanding teaching, learning and assessment," as well as the warm relationships that promote confidence and curiosity across year groups. Safeguarding procedures were described as very robust, with attendance across the school holding at a 95 per cent average.
A centenary year and a global ranking
The inspection result lands in what has been a milestone period for Tanglin. The school, founded in 1925 and the oldest British international school in Southeast Asia, celebrated its centenary in 2025. Its IB cohort that year achieved a 100 per cent pass rate with a provisional average diploma score of 39.3 points, well above the global average. In the 2026 Spears Schools Index, Tanglin was named one of the top 100 private schools in the world and among the top 15 in the Asia-Pacific region, marking the fifth consecutive year it has appeared in the ranking.
The BSO framework is voluntary for schools outside the United Kingdom, and Tanglin remains the only institution in Singapore to participate in it. That distinction matters commercially as well as reputationally: for British passport-holding families relocating to Singapore, an Ofsted-recognised outstanding grade is a credible signal of curriculum continuity, particularly for children who may return to the independent school sector in the UK.
Admissions context
The school is currently oversubscribed and operates a Waitpool system rather than a chronological waitlist, allowing a holistic review of applicants to maintain a balanced cohort. With 2,850 students across over 50 nationalities, Tanglin is also the only school in Singapore offering both A Levels and the IB Diploma as distinct sixth-form pathways, a structural feature that continues to differentiate it from newer British entrants to the city's competitive international school market.
