1. Identify the curriculum first
The curriculum determines assessment, subject choices and the qualifications a student earns. Ask whether the school offers the full pathway through graduation or only certain year groups.
2. Check accreditation and authorization
Verify claims with the relevant accrediting or curriculum body. Authorization to offer an IB program, for example, is different from simply using international teaching materials.
3. Understand admissions selectivity
Some schools accept students throughout the year, while others have tests, interviews, language thresholds or long waiting lists. Sibling priority and corporate-seat arrangements can affect availability.
4. Calculate all fees
Tuition may sit alongside registration, capital, technology, transport, meal, examination and activity fees. Ask which charges are refundable if the family relocates early.
5. Evaluate language support
A school can teach in English while still expecting a level that a newly arrived child does not yet have. Ask about English-language learning and support for the home language.
6. Look at teacher stability and class size
International schools can experience high staff turnover. Ask about teacher qualifications, retention and how the school maintains consistency across frequent student arrivals and departures.
7. Plan for university recognition
For older students, confirm that the final qualification is recognized by the universities and countries they are likely to apply to.
8. Compare the school community with your family’s timeline
A highly transient expatriate community may make arrivals easier but friendships more temporary. A more locally integrated school can provide continuity if you expect to stay long term.
9. Compare schools with evidence rather than the international label
Ask for the most recent accreditation or authorization status and verify it with the relevant body. The word “international” is not itself a quality standard; schools can differ enormously in governance, teacher qualifications, curriculum depth and the recognition of their final diploma.
Look at the full fee schedule over several years. Registration, capital levies, transport, meals, technology, examinations and trips can materially increase the published tuition. Families with more than one child should also check sibling discounts and whether deposits are refundable after a corporate relocation.
For secondary students, request university-destination data by curriculum and graduation year. This shows whether the school has experience guiding applications to the countries your child may target and whether subject choices support those pathways.
Finally, visit during a normal school day if possible. Observe class size, student movement, language use and the condition of facilities. A polished admissions tour is useful, but ordinary classroom atmosphere often says more about daily experience.
Check ownership and governance too. International schools may be nonprofit foundations, corporate groups, family-owned schools or branches of larger networks. Governance does not determine quality by itself, but it can affect fee increases, investment in facilities, leadership turnover and how complaints or safeguarding concerns are escalated.
Teacher turnover deserves a direct question. International education naturally involves mobility, but unusually high turnover can disrupt curriculum continuity and pastoral relationships. Ask how long senior leaders and subject teachers typically stay and how the school manages handovers when staff change between academic years.
