International School of Phnom Penh

"The International School of Phnom Penh is a private English-medium school located in Cambodia's vibrant capital city, offering families a rigorous, internationally recognized education within a welcoming community setting."

Designed to serve the needs of expatriate families, relocating professionals, and internationally minded local families alike, the school provides a coherent academic pathway from the earliest years of childhood through to upper secondary education. Founded in 2000, the International School of Phnom Penh has built its academic identity around the International Baccalaureate framework, one of the most respected and portable curricula in the world. The school delivers all three core IB programmes in sequence: the Primary Years Programme, the Middle Years Programme, and the Diploma Programme. This full continuum means that families who arrive in Phnom Penh can enroll children from nursery age and, should circumstances allow, follow a single consistent educational philosophy all the way through to the IB Diploma — a qualification recognized by universities across the globe. For families who move frequently, this alignment with the international IB community also eases transitions between schools in different countries, since the framework and its values travel well. All instruction at the school is delivered in English, making it a natural choice for anglophone families as well as for those who wish their children to develop strong English proficiency alongside their broader academic studies. The IB's inquiry-based approach runs through every level of the school, encouraging students to think critically, ask meaningful questions, and engage with the world around them — qualities that are particularly well suited to life in a dynamic and culturally rich city like Phnom Penh. Phnom Penh itself offers a compelling backdrop for an international education. The city sits at the confluence of the Mekong and Tonle Sap rivers and has undergone remarkable transformation in recent decades, emerging as a growing hub for business, diplomacy, and development work across Southeast Asia. Families stationed here through embassies, NGOs, international corporations, or development organizations will find in the International School of Phnom Penh a community that understands the particular rhythms and challenges of expatriate life. What distinguishes the school is its commitment to offering a complete, uninterrupted IB education from nursery through the final years of secondary school within a single institution in a city where internationally accredited options are still relatively limited. Parents evaluating schools for their children can take confidence in the school's two-decade presence in the city, its structured and globally recognized curriculum, and its position as part of an international educational community that extends well beyond Cambodia's borders. For families arriving in Phnom Penh and seeking an academically serious, English-language environment grounded in international best practice, the International School of Phnom Penh merits careful consideration.
