International Schools Association of Thailand (ISAT) is an association of private international schools in Thailand, headquartered in Pak Kret, Nonthaburi Province in Greater Bangkok.

During the past year, ISAT has been extensively involved with the Department of Export Promotion in the joint marketing of international education both in Thailand and overseas.

ISAT has lent its support to this process through assistance in in-service training by arranging placement for Thai teachers and administrators in international schools where they are able to observe modern approaches to teaching and learning first hand.

The organization of in-service training courses, particularly in the fields of cross-cultural management and Thai language teaching, also features highly on the list of ISAT's priorities.

ISAT has over 75 member schools[3] offering a range of curricula from American, British and International Systems.
