Eco International School

A fast-growing Phnom Penh group running early years, kindergarten and primary across four campuses, pairing the UK primary curriculum with the Cambodian national programme and a STEAM and environmental focus.

ECOIS now operates four sites: Samdach Pan Avenue in Daun Penh, two Chaktomuk addresses on Street 242, a Chbar Ampov campus on National Road 1, and a Veng Sreng campus due to open in August 2026. Class sizes are stated at 15 to 20, with bus services and a five-day trial for under-fives. The branding leans hard on character building and environmental education alongside academics.

The reach stops at Grade 6, so this is an early years and primary choice rather than a full pathway. Parent voice in English-language sources is sparse, which makes it harder to read independent of the school's own marketing. Best treated as a mid-market local option that suits Cambodian families wanting a UK-inflected primary close to home, with a clear plan needed for secondary at age 12.
