Established in 1995, Chatsworth International School is a three-programme IB school and is accredited by the Western Association of Schools and colleges (WASC)

Chatsworth International School is an IB World School, a member of East Asian Regional Council of Overseas Schools (EARCOS), is Edutrust certified (Singapore’s quality certification scheme), and Western Association of Schools and Colleges (WASC) accredited. A non-selective school, Chatsworth focuses on the holistic development of each individual student and prepares students to either enter universities around the world or to transfer to international and national system schools as their families move on from Singapore.


Chatsworth International School has been an IB World School since 2004. Chatsworth is authorised to offer all three programmes of the International Baccalaureate, which include:

  • Primary Years Programme (for students from Kindergarten to Year 6)
  • Middle Years Programme (for students from Years 7 to 11)
  • Diploma Programme (for students in Years 12 and 13)

Chatsworth was first awarded the four-year Edutrust certification in 2012. The school was one of the first international schools in Singapore to be awarded the four-year certification in our first Edutrust application. The certification was subsequently renewed in 2016. The current renewal is until February 2025.

The EduTrust Certification Scheme (EduTrust) is a voluntary quality assurance scheme administered by the Committee for Private Education (CPE) for private educational institutions in Singapore. It aims to distinguish private schools that are able to consistently maintain a high standard of quality in the overall provision of education services and make continual improvements that lead to positive student outcomes.
