Chatsworth International School Singapore

Located on Bukit Tinggi Road near the Bukit Timah Nature Reserve, Chatsworth became one of Singapore's first schools authorized for the IB Diploma Programme in 2004. The school delivers all three IB programmes - Primary Years Programme, Middle Years Programme, and Diploma Programme - creating a continuous pathway for students from K1 through Year 13.

The school supports multilingual development through its Mother Tongue Programme across MYP and DP levels, with 23% of 2025 graduates earning the prestigious IB Bilingual Diploma. With students representing approximately 55 nationalities, Chatsworth maintains a diverse international community while fostering close connections within its single-campus environment surrounded by Singapore's natural greenery.

What parents praise

Community is the word that keeps surfacing. Small classes, family atmosphere, around 50 nationalities. Parents on <a href="https://www.edarabia.com/chatsworth-international-school-bukit-timah-singapore/">Edarabia</a> describe it as inclusive and engaging. Teachers are well-regarded.named it Best IB School in Singapore for 2024. The Mother Tongue programme covers roughly 19 languages - a genuine differentiator.

Where it falls short

Facilities. The Bukit Timah campus is leafy but old, and parents notice. One on <a href="https://www.expatexchange.com/advice/62/25856/6/Singapore/Review-of-Chatsworth-International-School-in-Singapore">Expat Exchange</a> described the pool as "the size of the bath tub." On the <a href="https://forum.singaporeexpats.com/viewtopic.php?t=137171">Singapore Expats Forum</a>, several posters flag the for-profit ownership model. Teacher commentary on <a href="https://www.reddit.com/r/Internationalteachers/comments/1buc3kb/chatsworth_international_school_reviews/">Reddit</a> points to below-market pay and high workload.

The holding-school question

A persistent theme: families landing at Chatsworth while waiting for Tanglin, UWC or SAS. One parent on <a href="https://www.expatexchange.com/advice/62/25856/6/Singapore/Review-of-Chatsworth-International-School-in-Singapore">Expat Exchange</a> said directly that many students change school once accepted to their first choice. Whether that is fair or just Singapore's admissions market is debatable. IB DP average of 34.3 in 2025, 100% pass rate, per.

Bottom line

Solid IB school without the price tag or waitlists of Singapore's top tier. Community spirit is real, results are above the global average. Trade-off: older campus, limited space, second-choice reputation.
