As part of our promise to deliver the highest quality education to our students, Crescent has partnered with the Education Development Trust, and worked through an international school improvement process resulting in the International School Quality Mark (ISQM).The final report can result in Unsuccessful, Bronze, Silver, or Gold outcome.
Crescent is proud to have achieved a SILVER Award from the EDT on it’s first-ever accreditation with the global agency, putting it on par with hundreds of top-tier schools around the world. We were particularly pleased to have our standards of “Care & Support for Students” and “Partnership with Parents & Community” evaluated at the Outstanding or Gold level, and feel this speaks volumes about the priorities of our school community.

Previously known as the Centre for British Teachers (CfBT), the newly renamed Education Development Trust (2017) is a world authority on school inspection and evaluation having inspected schools around the world for more than 20 years. Utilising a transparent framework, they are passionate about working to raise standards in schools. They are one of only four agencies recognised in Thailand for accreditation services, including CIS, NEASC, and WASC.
