International Schools in Phnom Penh

Ages 2-15 · British · Other Phnom Penh · ~50 students

Shrewsbury Phnom Penh is the most premium choice in the city - backed by one of Britain's oldest schools and about to open the largest international school campus in Cambodia. At ~50 students it's very small right now, which is either an advantage or a concern depending on your priorities; families who value pastoral care and small classes will appreciate it, but those wanting a large peer group should wait until the new campus opens in September 2026.

Ages 3-18 · IB · Chamkarmon · ~875 students

ISPP is the default first call for most international families arriving in Phnom Penh - non-profit, parent-governed, strong IB results, and 35+ years in the city. If you're on a corporate package, it's a safe, well-regarded choice; if self-funding, the Grades 11-12 total of around US$29,500 warrants a close look at what's included.

Ages 3-18 · IB · Sen Sok · ~800 students

NISC gives you a full Nord Anglia IB school with an 8-hectare campus and genuine resources - a solid choice if the Sen Sok location works for you. Families closer to the city centre should factor in a 20-30 minute drive each way.

Ages 2-18 · IB, Australian · Sen Sok · ~441 students

AISPP is the right pick if you specifically need the IB Career-related Programme or the Australian Curriculum alongside IB, or if a large purpose-built campus matters to you. If you just want solid IB results, ISPP remains stronger on track record and governance - but AISPP's 100% 2025 pass rate is worth noting.

Ages 18 months-18 · Canadian, IB · Diamond Island / Koh Pich · ~1,000 students

CIS is the pick for families who want Canadian curriculum continuity, a French bilingual stream, or IB without the ISPP or NISC price tag. The Diamond Island location is central but ask about which campus your child would be on.

Ages 2-18 · British, Cambridge · Toul Kork · ~1,200 students

Paragon is the most affordable route to a CIS-accredited Cambridge education in Phnom Penh - a strong option for families who want recognised British qualifications without ISPP or NISC fees. Confirm which campus your child would be on before enrolling, as the school operates across three sites.

Ages 2-18 · Australian · Other Phnom Penh · ~300 students

AFIS is the pick for families specifically wanting the Western Australian Curriculum - it's the only school in Cambodia that delivers it, and graduates leave with both a recognised Australian diploma and a Cambodian one. The Chroy Changvar location is a significant commute from most international family housing, so factor that into your daily logistics before deciding.

Ages 18 months-14 · British, IPC · Chamkarmon · ~350 students

iCAN is the go-to option for families living in central Phnom Penh with primary-age children who want a British-style education without the ISPP or NISC price tag. It stops at Year 9, so plan the secondary school move in advance.

Ages 3-18 · British, Cambridge · Chamkarmon · ~300 students

Invictus is worth a serious look if budget is a real constraint and you want a full Cambridge IGCSE and A-Level pathway. At US$5K-US$11K per year, it's the most affordable full secondary school in the city. Just ask about staff stability and class sizes - the school has had turnover in the past.

Ages 3-18 · French · BKK / Daun Penh · ~1,290 students

If you're a French family or your children speak French, LFRD is the obvious choice - it's been in Phnom Penh since 1951 and runs a real French Baccalaureate pathway. For non-French families, the fees and language barrier make it a specialist option rather than a general one.

Ages 2-18 · Cambridge, International · BKK / Daun Penh · ~400 students

East-West is the most affordable route to Cambridge IGCSE and A Levels in central Phnom Penh. WASC-accredited, genuinely bilingual in English and Khmer, and well placed in BKK3 - it's worth a serious look if you want recognised Cambridge qualifications at fees below ISPP and NISC.

Ages 2-18 · American · Sen Sok · ~5,500 students

CIA FIRST is the school for families who want WASC-accredited American curriculum at a price point well below ISPP or NISC. At 5,500 students across four campuses it's by far the largest international school in Cambodia - if you want a big, diverse school environment, this is it; if you want a small community, look elsewhere.
