Ruamrudee International School

Ruamrudee International School (RIS) is a Catholic international school founded in 1957 in Lat Krabang district, east Bangkok. It is one of Bangkok’s older international schools and follows an American curriculum from Pre-Kindergarten through Grade 12.

Fees are generally lower than the most expensive central Bangkok international schools, which makes RIS a popular choice for families looking for an American curriculum school at a more manageable cost.

The Lat Krabang location is further from the main Sukhumvit expat corridor, but is close to Suvarnabhumi Airport and accessible via the Airport Rail Link (Lat Krabang station). Families living in the eastern parts of Bangkok or near the airport tend to find the commute practical.

The school has large grounds, sports facilities, a chapel, and a cafeteria. A strong alumni network within the Bangkok international community supports the school’s reputation.

Review the current fee schedule and confirm grade availability directly with the admissions office before applying.
