Accreditation & Affiliations


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.

Crescent International School is accredited by Accreditation Service for International Schools, Colleges and Universities (ASIC). The Centre has earned Premier status with ASIC for its commendable areas of operation. ASIC accreditation helps students and parents make a more informed choice and will also help a school, college, university, training provider or distance education provider, demonstrate to the international student body that they are a high quality institution.

ASIC is recognised by UKVI in UK, is a member of the CHEA International Quality Group (CIQG) in USA and is listed in their International Directory, is a member of the BQF (British Quality Foundation), are affiliates of ENQA (European Network for Quality Assurance) and are institutional members of EDEN (European Distance and E-Learning Network).

The International Schools Association of Thailand was established in 1994.

Its principal purpose is to act as a link between international schools which are members of ISAT on the one hand and the Ministry of Education, in particular the Office of the Private Education Commission, on the other.


ISAA is a small schools multi sports league, which has been running and increasing for several years.

This consists of league events consisting of at least 8 international participating schools in and around Bangkok. In addition to promoting competition, and sportsmanship, ISAA school heads are now collaborating to make greater interdisciplinary school links and activities amongst an extensive range of students.
