Founded in 1957, Ruamrudee International School (RIS) was one of the first international schools in Asia to be accredited by the Western Association of Schools and Colleges. Today, RIS continues to deliver an outstanding academic program and is a model of excellence and innovation in global education. The school's core values embed service learning, character development, and global citizenship into our enriched American curriculum. Our teachers are creative, compassionate experts in their fields; 72% of our faculty hold master’s degrees or higher.

An IB World School since 1998, RIS offers students a rigorous and extremely successful International Baccalaureate Diploma Program. Our IB Diploma students scored an average of 35 for the past three years, far above world averages. After graduation, our students go on to attend the most prestigious universities in the world and can then be found working in all branches of medicine; as government leaders, diplomats, and researchers; in the entertainment and film industries, as professional athletes, and in the emerging fields of AI and design technologies.

Located just outside of Bangkok, the school’s 29-acre clean-air campus is less than half an hour from Suvarnabhumi International Airport and is supported by a thriving local community. State-of-the-art facilities include 21st-century learning spaces, a culinary arts center, recording studio, Makerspaces, and a robotics lab. Our middle and high school students who live on campus enjoy a contemporary boarding facility with a warm, familial feel.

At Ruamrudee International School, we nurture the minds, hearts, and hands of our students. From PreK 2 through grade 12, students benefit from small class sizes, relevant and innovative electives, modern languages, a vibrant performing and visual arts program, and one of the largest athletic programs of any international school in Southeast Asia. RIS offers a comprehensive extended day program with creative enrichment opportunities. Our Student Services department, led by school psychologists, ensures that our English Language Development and Learning Support programs meet the diverse needs of all our students. All RIS students are able to excel, both in and out of the classroom.

As it has been for the last 60 years, our deeply ingrained culture of self-reflection and self-improvement has resulted in students who are creative, compassionate, critical thinkers. Their commitment to leading happy, healthy lives while helping others do the same is why RIS students continue to forge positive, lasting legacies for the world.
