RIS Ruamrudee International School, founded in 1957 by the Catholic Redemptorist Fathers, is one of Thailand's longest-established international schools and among the first in Southeast Asia to be accredited by WASC. Guided by a mission of interfaith, inclusive, and academically rigorous education, RIS fosters intellectual growth, moral character, and global citizenship.
The 29-acre Minburi campus serves over a thousand students and is supported by four affiliate campuses across Bangkok and Phuket. Facilities include performing and visual arts studios, design and robotics labs, a culinary center, and a contemporary boarding residence for students aged 12 to 18.
RIS follows a modified American curriculum, with a Reggio-inspired Early Childhood program and AERO- and NGSS-aligned instruction through middle school. High school students may pursue the IB Diploma or Advanced Placement courses.
IB students at RIS continue to exceed global averages. Results for the Class of 2025 include a 97% pass rate, a 34-point RIS average (worldwide average: 30), 54% earning the Bilingual Diploma, and a top score of 45. The school currently offers 22 IB courses, with CAS (Creativity, Activity, Service) and TOK (Theory of Knowledge) integrated into the Values curriculum to ensure meaningful, community-focused learning experiences.
RIS graduates attend leading universities worldwide, and its alumni network includes distinguished professionals in diplomacy, medicine, research, entrepreneurship, entertainment, athletics, and emerging fields such as AI and design technologies.
