Ruamrudee International School

Ruamrudee International School (RIS) is a prestigious American international school founded in 1957 by the Brothers of St. Gabriel, a Catholic religious order. Set on a beautiful 22-acre campus, RIS offers an American-style college preparatory curriculum from Pre-Kindergarten through Grade 12, alongside the IB Diploma Programme.

RIS is one of Bangkok's most respected international schools, known for its strong academics, values-based education, and outstanding university placement results. The school's diverse community of approximately 1,800 students from over 50 nationalities reflects Bangkok's cosmopolitan character, and its Catholic mission provides a strong ethical foundation.

The campus features exceptional facilities including a sports complex, 400-metre track, swimming pool, chapel, performing arts centre, and modern science and computer laboratories. RIS's combination of American educational rigour, Catholic values, and Thai cultural context makes it a unique and highly sought-after school.
