International School of Phnom Penh
Cambodia's oldest international school (1989), non-profit and parent-governed, running the full IB continuum from Early Years through Diploma. 2025-26 tuition runs from US$8,356 (EY1) to US$26,871 (Grades 11-12) plus an annual capital levy of US$1,202-US$2,662.
In brief
Cambodia's first international school, founded in 1989 by a small group of NGO families and now the established IB-continuum option for serious expat and senior Cambodian families.
ISPP runs the full IB continuum across PYP, MYP and Diploma on a purpose-built six-hectare campus on Hun Neang Boulevard in Mean Chey, where the school moved fully in 2015. Around 900 students from roughly 50 nationalities sit alongside Olympic-size pool, performing arts theatre, sports fields and library facilities that comfortably outclass anything else in the city. The school stays parent-governed and not-for-profit, with surpluses reinvested into the campus.
The pull is academic rigour, a genuinely diverse cohort and a strong IB Diploma track record into competitive universities. Mother-tongue support runs to around fourteen languages, which helps families holding French, Korean, Japanese or Khmer alongside English. The trade-off is price. Fees range from roughly USD 9,500 at the youngest end to close to USD 30,000 in the senior years, plus a USD 3,500 entrance fee, which puts ISPP firmly in the top tier of Phnom Penh costs.

Reviews
- ISPP is consistently positioned as Cambodia's leading international school; teachers describe it as the obvious choice in Phnom Penh and a clear step above the alternatives.
- Parents praise the academic rigour, the IB continuum from PYP through Diploma, the Olympic-size pool and the wider campus, and call teachers dedicated and passionate.
- Fees are around 9,500 to 29,000 US dollars a year before one-off entry costs; r/cambodia threads note the cost puts it out of reach for most local families.
- Compensation is a recurring positive in teacher discussions, with ISPP reportedly paying among the top two or three schools in the city; one reference cited a base around 50,000 US dollars plus saving potential.
- Accreditations: WASC, CIS, and full IB World School authorisation across all three IB programmes.
