Founded in 1957, Ruamrudee International School (RIS), Bangkok, Thailand, continues to deliver an outstanding academic program and is a model of excellence and innovation in global education. The school’s core values of service-learning, character development, and global citizenship are embedded in our enriched American curriculum. Our teachers are experts in their fields; 72% of our faculty hold master’s degrees or higher.

RIS offers a rigorous and successful curriculum with multiple opportunities for students to pursue their individual interests and passions through our Focus and Flex Blocks embedded in their daily schedules. RIS is also one of few international schools to offer both the International Baccalaureate Diploma Program (IBDP) and the AP track. Regardless of their course choices, our students consistently score far above world averages and go on to attend the most prestigious universities in the world. RIS alumni can then be found working in every imaginable field—as government leaders, diplomats, and researchers; in all branches of medicine; in the entertainment and film industries, as professional athletes, and in AI and design technologies.

Facilities on our 29-acre Minburi campus (Ramkhamhaeng 184) include newly renovated learning spaces, including the main library, a culinary arts center, a recording studio, an industrial arts lab, a robotics lab, and a FINA-approved Olympic-sized pool. Our middle and high school students who live on campus enjoy comfortable, safe boarding facilities.

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 also offers a comprehensive extended day program with unique learning experiences. Our Student Services department, led by school psychologists, ensures that our English Language Development and Learning Support programs meet the diverse needs of our students so they are able to excel, both in and out of the classroom.

As it has been for the last 63 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 legacies throughout the world.
