Phnom Penh is one of Southeast Asia's quietest postings for international families — and one of the more interesting in terms of value. Cambodia's capital has built a credible international school sector over the last decade, driven by NGO families, regional headquarters and a fast-growing Cambodian middle class. Fees sit well below Bangkok, Ho Chi Minh City and Kuala Lumpur for comparable programmes, and most major curricula are now available.
This guide explains how to choose an international school in Phnom Penh in 2026: which curricula are offered, the leading schools, what fees actually look like, and the practical decisions families face on arrival.
Why Phnom Penh for an international education
Phnom Penh's international school market has matured significantly since 2015. The city now hosts well-regarded American, British, Australian and Singaporean-style international schools, alongside several Christian and bilingual options. Class sizes are typically smaller than in larger Southeast Asian capitals, which helps newly arrived non-English-speaking children settle in faster. Cost of living is materially lower than Bangkok or Singapore, which translates into both lower fees and easier-to-find family housing.
Curricula available in Phnom Penh

- Australian curriculum (HSC and IB Diploma): Australian International School Phnom Penh delivers the New South Wales curriculum.
- International Baccalaureate (IB): A small number of IB World Schools, mostly in the Diploma Programme.

2026 fees in Phnom Penh
Cambodia's currency is the riel but fees at international schools are universally quoted in US dollars, which simplifies budgeting. Indicative 2026 annual tuition:
- Early Years and Primary: USD 5,800 – 14,500
- Lower Secondary: USD 7,500 – 17,500
- Upper Secondary / IB Diploma / A-Level / AP: USD 9,800 – 22,000
Enrolment fees range from USD 500 to USD 2,500 and are typically non-refundable. Capital levies or building funds (USD 200–800 per year) are common. Lunch, transport, books and uniforms are extras and usually add USD 1,200–3,000 per child per year.
Neighbourhoods and the school commute
- Toul Kork: Popular with expat families for residential streets, family compounds, and reasonable proximity to several international schools.
- BKK1 and BKK3: Central, more apartment-style. Convenient for parents working downtown.
- Chamkar Mon and Tonle Bassac: Riverfront living, several international schools within 15 minutes.
- Sen Sok (north): Newer suburbs with house compounds and several growing schools. Longer commute to the city centre.
Admissions tips for expat families
- Apply 3–6 months in advance for top schools. Most accept rolling applications and the bigger constraint is housing rather than school place availability.
- Cambodia's school year runs August to June for international schools, but several local-bilingual schools follow an October-July calendar — confirm with each school.
- Bring apostilled academic transcripts and the child's vaccination record; some schools also require a medical certificate from a Phnom Penh-registered doctor.
- Visit at least three schools in person. Marketing materials in Phnom Penh vary widely in accuracy.
- Ask explicitly about teacher qualifications and turnover — quality varies more between schools here than in larger international hubs.
What to ask about Khmer language and culture
Most expat families staying 3+ years value some Khmer exposure for their children, even if academic instruction is in English. Schools vary widely:
- True bilingual Khmer-English schools (Asian Hope, several local bilinguals) embed Khmer across the day.
- International schools with optional Khmer typically offer 2–3 hours per week, with limited curriculum depth.
- Strict international schools may offer no Khmer at all, expecting families to organise tutors privately.
For families on 1–2 year postings, no Khmer is usually fine. For longer stays, look for at least one daily Khmer period.
Frequently asked questions
Are Phnom Penh international school fees really lower than Bangkok or Singapore?
Yes. Comparable American and British curriculum schools in Phnom Penh run roughly 40 to 60 percent below Bangkok and 60 to 75 percent below Singapore. The lower fees reflect smaller school sizes, lower local costs, and a less mature premium market.
Will my child be ready for IGCSE or AP from a Phnom Penh school?
Yes, at the established schools (AISPP, Invictus, Logos). Confirm the exam centre's results history for the last three years — schools should be willing to share aggregate IGCSE, A-Level or AP data.
Do I need a visa before enrolling my child?
Cambodia's E-class business visa or related dependent visas are usually sufficient. Schools accept enrolment applications before visa is finalised but require visa or work permit documentation before the place is formally confirmed.
