USA International School is founded by a group of local educators in 2001 at Battambang province and 2011 at Phnom Penh. The school provides students with a holistic and broad-based education. Under the bilingual concept, every student mainly learns English which is the common working language at school. We have adopted a prestigious curriculum, the Cambridge Curriculum to ensure that the skills and knowledge taught in school meet the challenges of the 21st century and the millennium goals set by of the Royal Government of Cambodia.
