Educational accreditation is a type of quality assurance process under which services and operations of educational institutions or programs are evaluated by an external body to determine if applicable standards are met. If standards are met, accredited status is granted by the agency. In Thailand all International School are required by the Thailand’s Ministry of Education to obtain a local quality assurance as well as an overseas accreditation.

Overseas and Local Accreditation

From the inception of the school, TRIS has worked with the Western Association of Schools and Colleges (WASC) to provide us with an external overseas accreditation. WASC is one of six regional accrediting associations in the United States. This is the same accreditation institution that gives accreditation to the universities in western part of the United States including Standford university, University of California – Berkeley, University of California – Los Angeles and etc. The Commission provides assistance to schools located in California, Hawaii, Guam, the Commonwealth of the Northern Marianas, American Samoa, the Federated States of Micronesia, the Republic of the Marshall Islands, and East Asia including Thailand.

Since 2008 TRIS has been accredited by WASC and as a result of that TRIS students are well accepted in all universities in Thailand and around the world. Transferring from TRIS to another school, college or university in Thailand or anywhere in the world is possible.

In the same year, TRIS has also been accredited by Thailand’s Office for National Education Standards and Quality Assessment (ONESQA). The Office for National Education Standards and Quality Assessment (Public Organization) is an academic body specializing in educational quality evaluation. It has the objective of enhancing the quality of the education provision system in Thailand, enabling the educational institutions to provide quality education to learners, who will be endowed with virtue, competence and happiness.


In order to establish an international school in Thailand, international school license has to be granted from the Office of the Private Education Commission of the Thailand’s Ministry of Education. TRIS was awarded the international school license since 2003 permitting TRIS to operate kindergarten, elementary, middle and high school using American (California) curriculum. On the other hand, TRIS has obtained a license to use the California State curriculum from the California Department of Education, U.S.A. For more information about the curriculum, please see topic under Academics.

TRIS has also been given permission to use the California Department of Education (CDE) curriculum. TRIS was the first school in Thailand to be granted this permission.
