Established in 1957 by the Redemptorist Fathers, RIS was one of the first schools in Asia to be accredited by the Western Association of Schools and Colleges (WASC) and the Thai Ministry of Education. RIS is also a member of the East Asia Regional Council of Overseas Schools (EARCOS) and the Council of International Schools (CIS). 

Ruamrudee is Thai for “union of hearts,” which perfectly captures the school’s philosophy of welcoming all children into an environment of care and compassion. RIS embraces a progressive, innovative approach to education, emphasizing global citizenship and character development in a multicultural community.
