International Schools in Phnom Penh: How to Choose the Right One

Prepared by the NovAsia Editorial Team

Choosing an international school is one of the most consequential parts of moving to Phnom Penh with children. The city offers British, American, Canadian, Australian and International Baccalaureate pathways, but the label on a school's website tells parents surprisingly little about what daily life will be like for their child.

The most useful question is not, “Which is the best international school in Phnom Penh?” It is, “Which school is the best fit for this child, at this stage, in this family's real life?” A highly regarded school may be wrong for a child who needs a smaller setting, stronger English-language support or a shorter school day. A less prominent school may be a better choice if it offers a stable teaching team, a suitable academic route and a sustainable journey from home.

This guide is designed as a decision framework, not a ranking. Fees, admissions policies, accreditations, transport routes and support services can change, so every important point should be confirmed directly with the school before a family pays a deposit or signs a long lease nearby.

Start with the child, not the school list

Before booking campus tours, write down the child's actual needs. This reduces the risk of being swayed by branding, impressive buildings or other families' preferences.

Key questions include:

1. How old is the child, and which year group would they enter?
2. What language are they currently educated in?
3. Is their English conversational, academic or still at beginner level?
4. How do they respond to change, large groups and competitive environments?
5. Does the family expect to stay in Cambodia for one year, several years or indefinitely?
6. Is a particular upper-school pathway important, such as IB, IGCSE, A Levels or a North American diploma?
7. Does the child need EAL, learning support, counselling or other specialist provision?
8. What is the complete annual budget, including fees outside tuition?
9. How much daily travel can the child realistically tolerate?
10. What would make the move feel safe and manageable during the first term?

These questions matter more than general prestige. A six-year-old entering English-medium education for the first time has different priorities from a 16-year-old who needs specific subjects for university entry.

What families commonly compare in Phnom Penh

Families often look at schools such as International School of Phnom Penh, Northbridge International School Cambodia, Australian International School Phnom Penh, Canadian International School of Phnom Penh, iCAN British International School and other established or newer providers. This is not a ranking, and a name appearing in a relocation guide should never be treated as an endorsement.

For each school, verify the current campus, year groups, curriculum authorisation, accreditation, admissions capacity, fee schedule, language support and safeguarding arrangements directly. Status can differ by programme or campus, and published information may change between academic years.

Understand the main curriculum pathways

International schools in Phnom Penh use several educational models. The right one depends on the child's current school history, likely next destination and preferred style of learning.

International Baccalaureate

The International Baccalaureate is built around inquiry, conceptual understanding, research, reflection and international-mindedness. It can suit mobile families because the programme is recognised across many countries and is offered in a structured sequence from primary through to the Diploma Programme at authorised schools.

It is not automatically the best fit for every learner. The later years can involve substantial independent work, extended writing, project management and reflection. Parents should ask how the school supports students who are new to the programme rather than assuming that the IB name guarantees an easy transition.

British pathway

A British-style school commonly works towards IGCSEs and, in the final years, A Levels or another post-16 qualification. The pathway can offer a clear subject structure and, at A Level, relatively early specialisation.

Families should confirm exactly which qualifications the school offers, which examination boards it uses and whether all advertised subjects run every year. A broad subject list on a website does not guarantee that every option will be available to a small cohort.

American pathway

American-style programmes usually maintain a broader subject mix through high school and may lead to a US high-school diploma, sometimes with Advanced Placement or other externally recognised courses.

This can suit children who value flexibility or are likely to apply to North American universities. Parents still need to ask how credits transfer, how the diploma is accredited and what counselling is available for university applications outside the United States.

Canadian and Australian pathways

Canadian and Australian schools may follow a provincial or state-linked curriculum or a school-designed international version of one. The important questions are practical: what qualification the student receives, how progress is assessed, how easily the child can transfer and where graduates typically continue their education.

Do not choose a curriculum because its national label sounds familiar. Ask how it operates in the specific school, with the specific year group and current staffing.

Age changes the decision

Early Years and primary school

For younger children, the everyday environment matters as much as the formal curriculum. Look at:

• adult-to-child ratios;
• warmth and consistency of classroom relationships;
• supervised play and movement;
• shade, drinking water and heat management;
• safe handover at arrival and collection;
• language support through play and routine;
• communication with parents;
• rest, meals and toileting arrangements where relevant.

A beautiful campus is useful only if the child feels secure, understood and able to participate.

Middle school

At this stage, children often need both academic structure and social support. Ask about subject breadth, homework expectations, English-language support, pastoral care, sport, arts and the way the school handles friendship difficulties or bullying.

A move that looks straightforward on paper can be emotionally demanding. A child may understand spoken English but struggle with subject vocabulary, written assignments and the social codes of a new school.

Upper secondary school

For teenagers, timing becomes critical. Changing curriculum during IGCSE, A Level, IB Diploma or another senior programme may affect subject continuity, assessment and university applications.

Parents should confirm:

• which subjects are actually available;
• minimum numbers required for a course to run;
• entry requirements for senior programmes;
• how previous credits or grades are recognised;
• language requirements;
• university and careers counselling;
• examination fees;
• what happens if the student transfers again.

A school can be excellent in primary education and still offer a senior pathway that does not suit a particular student.

Conversational English is not academic English

A child may chat confidently with classmates and still find science reports, history essays, maths instructions or extended reading extremely difficult. This distinction is frequently underestimated by families moving from a Russian-medium or other non-English school.

Ask the school:

• how English proficiency is assessed;
• whether support is called EAL, ESL or something else;
• whether it is available in the relevant year group;
• how many hours of support the child may receive;
• whether the student leaves mainstream lessons for support;
• how progress is reviewed;
• whether there is an additional charge;
• how long support can continue;
• how teachers adapt subject lessons while English develops.

Strong support is coordinated. It should not consist only of an admissions test followed by the expectation that the child will “pick it up”. For older students, the school should explain honestly whether the academic timetable leaves enough time to build the required language level.

Accreditation: what to verify

Accreditation can provide evidence that a school has undergone external review and meets a recognised set of standards. It can also make records, credits and qualifications easier to understand when a student transfers internationally.

However, parents should verify the exact claim. Schools may refer to:

• authorisation to deliver an IB programme;
• membership of an educational association;
• candidacy for accreditation;
• accreditation of the whole school;
• approval of a particular examination centre;
• recognition of a specific diploma.

These are not interchangeable.

Check the accrediting organisation's own directory rather than relying only on the school website. Confirm the current status, the campuses and age ranges covered, and the date of the latest review. A logo alone does not show whether a school is fully accredited, a member or an applicant.

Accreditation is an important filter, not a guarantee that a particular child will thrive there.

School culture can matter more than facilities

Two schools with similar curricula may feel completely different. Culture appears in small, observable details:

• how teachers speak to children;
• whether staff know students by name;
• how leadership responds to difficult questions;
• whether parents are treated as partners;
• how mistakes and behaviour are handled;
• whether achievement is defined only by examination results;
• whether quieter or less confident children receive attention;
• how new students are introduced to the community.

During a visit, look beyond the admissions presentation. Are children engaged or visibly tense? Are displays dominated by polished marketing material, or do they show real student work? Do teachers appear approachable? Are common areas calm and supervised?

A school that talks only about buildings, awards and university destinations may not be giving enough attention to wellbeing. A school that emphasises warmth but cannot explain academic progression may have the opposite weakness.

Safeguarding must be more than a policy document

For parents, safeguarding means much more than guards at the gate. A serious school should be able to explain how it protects children in classrooms, online, on buses, during activities and when concerns are raised.

Ask about:

• background checks and safer recruitment;
• staff safeguarding training;
• the designated safeguarding lead;
• how children and parents report concerns;
• supervision outside lessons;
• collection and authorised pickup procedures;
• school-bus supervision;
• anti-bullying procedures;
• online safety;
• photography and data consent;
• counselling and mental-health support;
• escalation when there are concerns about abuse, self-harm or serious distress.

The existence of a written policy is only the first step. Ask for a practical example of what happens when a concern is reported. Staff should know the process without improvising.

For any urgent concern about a child's safety or mental health, parents should seek qualified professional help rather than relying on a general school guide or informal community advice.

Learning support and additional needs

International schools differ significantly in their ability to support dyslexia, ADHD, autism, anxiety, speech and language needs, physical disability and other learning differences.

Do not assume that the phrase “inclusive school” means the school can meet every need. Ask directly:

• which needs the school can currently support;
• which specialists are employed in-house;
• whether external therapists can work on campus;
• whether a formal assessment is required;
• how individual plans are created and reviewed;
• whether classroom assistants are available;
• what additional fees apply;
• what would happen if needs become apparent after admission;
• under what circumstances the school may say it cannot continue the placement.

It is better to receive a clear limitation before enrolment than to discover after the move that the child cannot access appropriate support.

Staff stability and teacher quality

International schools often employ teachers on fixed-term contracts, so some turnover is normal. What matters is whether changes are manageable and whether the school retains experienced staff in key roles.

Useful questions include:

• average teacher tenure;
• turnover in the child's division;
• qualifications required for teachers;
• induction for new staff;
• availability of EAL, learning-support and counselling specialists;
• class size and teacher workload;
• who parents contact when a problem arises.

A school should not be judged on one departing teacher. Repeated turnover in leadership, pastoral care or core subjects is more significant because it can weaken continuity.

The journey can undermine an otherwise good choice

Phnom Penh traffic makes school location a major quality-of-life issue. A route that looks short on a map can become exhausting during the morning school run, evening congestion or heavy rain.

Test the journey on a normal weekday at the actual departure and collection times. Measure the entire routine:

leaving home + waiting + travel + drop-off + return journey

For younger children, a long bus journey affects sleep, breakfast, concentration and after-school energy. For working parents, an unreliable route can dominate the household schedule.

School buses

Confirm:

• whether the route serves the intended address;
• whether there is space;
• estimated time on the bus;
• adult supervision for younger children;
• seat-belt policy;
• vehicle tracking or communication;
• pickup and drop-off procedures;
• late buses after activities;
• what happens during rain or traffic disruption;
• the annual or termly fee.

A school-bus service should not be assumed simply because the school advertises transport. Routes and capacity can change.

Calculate the full annual cost

Tuition is often only one part of the school budget. Families should request a written fee schedule covering the full academic year.

Potential costs include:

• application and assessment fees;
• registration or enrolment fees;
• refundable or non-refundable deposits;
• capital or development levies;
• tuition;
• uniforms;
• devices and software;
• books and materials;
• meals;
• transport;
• examinations;
• field trips;
• residential trips;
• music tuition;
• sports travel;
• after-school activities;
• EAL or learning support.

Ask what is refundable, what is due before a place is confirmed and what happens if the family leaves mid-year. A lower headline tuition fee can become similar to a higher-priced school once extras are included.

After-school activities: useful, but not the deciding factor

Activities can help a child make friends and settle into a new school. Sport, music, theatre, robotics and clubs may be a genuine strength, especially for teenagers.

Check what is actually available to the child's year group in the current term. Ask:

• whether places are limited;
• whether selection or auditions apply;
• who teaches the activity;
• whether it is included in fees;
• how often it runs;
• whether competitions or weekend commitments are compulsory;
• whether a late bus is available;
• whether activities change each term.

A long list on a website may include programmes that do not run every year. One or two sustainable activities are often more valuable than an impressive catalogue that the child cannot access.

Food, nursing and everyday care

These operational details strongly affect family confidence.

Ask how the school handles:

• meals and snacks;
• allergies and dietary restrictions;
• drinking water;
• school nursing;
• prescribed medication;
• fever, vomiting or injury;
• contact with parents;
• emergency transfer to hospital;
• medical records and consent;
• heat and air-quality precautions during sport.

A school should be able to explain who assesses a sick child, where the child waits and when parents are called. Families with severe allergies, diabetes, epilepsy or other medical needs should create an individual plan with the school and the child's clinician.

How to use a campus visit

A useful visit has three parts:

1. Listen to the admissions presentation.
2. Observe the school in operation.
3. Ask specific questions that relate to the child.

Look at the real learning environment rather than only the newest facilities. Notice classroom noise, student work, supervision, shade, drinking-water access, transitions between lessons and the way adults respond to children.

Questions for admissions or academic staff might include:

• How do you support a student joining mid-year?
• How is academic English assessed and supported?
• What happens if a child struggles emotionally after the move?
• How many students are in the class?
• How stable is the teaching team?
• How is progress reported?
• What is the safeguarding reporting route?
• Is there a counsellor?
• Is there a waiting list for this year group?
• What costs are not included in tuition?
• What qualifications do graduates receive?

General answers such as “we are very international” or “every child is supported” should be followed by a request for a concrete example.

Speak to current parents carefully

Current families can reveal issues that are not visible on a tour. Ask about specific experiences rather than whether they simply “like the school”.

Useful questions include:

• How did the child settle in?
• How does the school communicate when something goes wrong?
• Is the journey sustainable?
• How stable are the teachers?
• Are activities genuinely available?
• Were there unexpected costs?
• Does the bus work as promised?
• How effective is English-language support?
• What do you wish you had known before enrolment?

One enthusiastic or unhappy parent should not decide the choice. Repeated themes across several independent conversations are more informative.

Common mistakes

Choosing by brand alone

Recognition can be useful, but it does not prove that the school suits the child's personality, language level or academic needs.

Overestimating English

Social fluency is not the same as academic readiness. Ask for evidence and a support plan.

Underestimating travel

A strong school can become the wrong choice if the child spends hours each day in traffic.

Comparing tuition only

Use the full annual cost, including transport, support, exams and activities.

Arriving without time

Starting the search only days before term begins can leave the family choosing from the places still available rather than the schools that fit best.

Ignoring the child's temperament

A large, highly competitive school may be energising for one child and overwhelming for another.

Focusing on the campus

Buildings do not replace teaching quality, safeguarding, pastoral care or stable leadership.

Ignoring the next transition

For older students, confirm how the chosen programme connects to university or to the family's likely next country.

Build a shortlist using the same criteria

Once the family has visited several schools, reduce the list to three or four realistic options and compare them consistently.

Separate facts from impressions. “The school has current IB authorisation” is a fact. “It felt friendly” is an observation. “The bus route should improve” is an assumption until confirmed.

Final perspective

The best international school in Phnom Penh is not necessarily the most expensive, the largest or the most widely known. It is the school where a particular child can learn, feel safe, build relationships and move through an academically coherent programme without the family's daily routine becoming unsustainable.

Begin early. Verify accreditation and qualifications directly. Test the journey. Ask detailed questions about English support, safeguarding, learning needs, staff stability and the full fee structure. Most importantly, include the child in the process at an age-appropriate level.

A school decision cannot remove every difficulty from an international move. It can, however, give the child a stable base from which the rest of the family's life in Phnom Penh becomes much easier to build.

Frequently asked

When should families start looking for an international school in Phnom Penh?

Ideally, begin several months before the move or the start of the school year. This allows time to compare curricula, verify places in the relevant year group, complete assessments and test the school journey in real traffic.

Is a school ranking more important than its curriculum?

Usually not. A school should be judged by how well it fits the individual child: age, current language of instruction, academic pathway, learning support, wellbeing, journey time and the family's sustainable budget.

Can parents choose a school on the strength of its campus alone?

No. Facilities matter, but they do not prove teaching quality, safeguarding, accreditation, staff stability or effective support for a child who is new to English or to international education.
