Ruamrudee International School (RIS) has spent 64 years honing its ethos, learning from its collective experience, and refining its rich academic tradition. Today, RIS is one of Thailand’s leading international schools and is a model of excellence and innovation in global education. Launched in August 2019, the RIS Ratchapruek campus is located on Bang Kruai - Sai Noi Road and approximately three kilometers from The Walk Ratchapruek. RIS Ratchapruek follows a modified American curriculum and is open for students from Pre-K 2 to Grade 8, with plans to expand up to Grade 12 in future years.

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.

Over 60 Years of Excellence in Education

RIS Ratchapruek is committed to providing students with real-world, experiential activities and challenges, which lead them to also excel beyond the classroom. 

Reflecting the school’s mission and vision, RIS Ratchapruek students participate in a comprehensive range of service learning opportunities with charities and communities throughout Thailand. These experiences change the lives of not only the people in these communities but of the students as well. RIS does more than just educate students; RIS nurtures their heads, hands, and hearts.
