Start with the family, not the school

The most common mistake we see in the international school search is families starting with the school. They tour campuses, read rankings, gather brochures, and only then ask the harder questions about what they actually want for their child. The result is a shortlist optimised for prestige rather than fit, and a decision that often unwinds within two years.

Before anything else, write down three things on a single sheet of paper. First, the kind of person you want your child to become by the time they leave school: confident, curious, kind, academically strong, athletically capable, multilingual, internationally minded. Second, your real constraints: budget, location, length of stay in the country, languages spoken at home, any special learning needs. Third, the decision criteria you would defend at a dinner party: not "best school" but "best fit for our specific situation".

That sheet of paper is your filter. Every school you tour, every ranking you read, every parent review you weigh, gets evaluated against it. The schools that float to the top will not always be the most prestigious or the most expensive. They will be the ones that match your family.

The 12 factors that actually matter

Across the 50 cities and 1,000+ schools we cover, the same 12 factors emerge as the ones that genuinely separate good fit from poor fit. We list them in the order parents typically encounter them, not in order of importance. The right weighting depends on your family.

  1. Curriculum. Defines pedagogy, exam structure, and university pipeline. See our curriculum guide for the trade-offs.
  2. Accreditation. Is the school properly recognised by the body whose curriculum it teaches?
  3. Fees and total cost. Tuition is roughly 75% of what you actually pay. See the hidden fees that double the sticker price.
  4. University outcomes. Where does the school send its graduates, and to what kind of programmes?
  5. Class size and student-teacher ratio. Especially material in primary years.
  6. Faculty stability. Annual teacher turnover under 12% is healthy. Above 25% is a warning.
  7. Language of instruction. English, bilingual, or destination language? This shapes integration.
  8. Cohort composition. What percentage are local versus expat, single-nationality versus diverse?
  9. Pastoral and learning support. SEN provision, ESL, counselling, anti-bullying culture.
  10. Co-curricular depth. Sport, arts, service, extracurriculars. Are they real or marketing?
  11. Commute and location. A 60-minute morning commute will define your child's energy more than the school will.
  12. Stability and exit options. Will the curriculum and credentials transfer if you move again?

Curriculum: the choice that frames everything

Curriculum is the single decision with the longest reach. It determines what your child studies, how they are assessed, which universities recognise their qualifications, and how easily they can transfer if you move again. The good news is that there are really only 10 mainstream international curricula, and they cluster into a handful of decision points.

If your child is likely to go to university in the United Kingdom, Europe, Asia, Australia, or Canada, the International Baccalaureate (IB) and the British curriculum (IGCSE / A-Level) are the two strongest defaults. The IB is broader, more interdisciplinary, and includes a research and creativity component built in; the British curriculum is more specialised in the final two years and lets students go deep in three or four subjects. Both are recognised globally; the choice often comes down to your child's learning style and the universities you are aiming at.

If your child is likely to go to university in the United States, the American curriculum (AP and High School Diploma) is the most direct path. It builds a GPA across four years of high school and uses Advanced Placement courses to demonstrate university-level work. American universities understand the IB and British qualifications too, but they read the American transcript more fluently.

If you want bilingualism baked in, look at the French and German systems, or the growing category of dedicated bilingual schools. If you are drawn to a particular pedagogy, look at Montessori for early years and primary, or the Finnish system if you can find a credible licensed provider abroad.

Fees, and the line items most schools hide

The published tuition figure on a school's website is rarely what families end up paying. We routinely see total annual cost run 30 to 50% above the headline number once all charges are accounted for. The major hidden categories are:

  • Application and registration fees: $100 to $1,000, usually non-refundable.
  • Capital levy or building fund: annual contribution towards facilities, often $1,500 to $5,000.
  • Refundable deposit / debenture: a deposit of one to two terms' fees, returned only on departure (and sometimes only after the seat is re-sold).
  • Educational support services (ESS): for children needing English support or learning support, typically $4,000 to $12,000 extra per year.
  • Bus, lunch, uniform, technology levies: typically $2,000 to $4,000 per child per year combined.
  • Trips, clubs, exam fees: $1,000 to $3,000 per year, more in upper school.

For an honest planning number, take the published tuition and add 30%. For premium schools in Geneva, Hong Kong, New York and London, add 40%. Then run the calculation across all your children, all the years you expect to be in the country. Use our fee calculator to model the total cost. The result is sobering, and it is the right number to budget against.

Accreditation: which marks count

Accreditation is the most-misunderstood part of school marketing. Schools love to list every body they belong to. Most of those listings are membership, not accreditation. The distinction matters: membership is a paid relationship; accreditation is an external evaluation against published standards.

The accreditations worth paying attention to are:

  • Curriculum-issuing bodies: IB World School authorisation (IBO), Cambridge Assessment International Education, Pearson Edexcel, AdvancED / Cognia for American programmes. If a school teaches a curriculum, it must be authorised by the issuing body. Verify on the issuing body's official school finder.
  • Regional / national accreditation: CIS (Council of International Schools), NEASC, MSA-CESS, BSO (UK Department for Education's overseas inspection scheme). These are independent evaluations, typically every 5 years, and rigorous.
  • Government regulation: in many countries (UAE, Singapore, Hong Kong, Saudi Arabia) the local education authority publishes inspection reports. KHDA in Dubai, MOE in Singapore, EDB in Hong Kong, ETEC in Saudi Arabia. These are public and unsparing. Read the latest report.

What is not accreditation: membership of CIS, COBIS, ECIS, or AAIE. These are professional networks. Useful, but not a quality signal in themselves. A school that lists "member of CIS" but not "accredited by CIS" is making a meaningful distinction by omission.

How to tour a school properly

Most parents tour 5 to 8 schools and find by the third tour that the marketing version blurs together. Approach it with structure and the differences become clear.

Before the tour

  • Read the school's most recent inspection or accreditation report. Bring questions about anything flagged.
  • Read the school's published university destinations list. Look for the long tail, not the prestigious headline.
  • Read 5 to 10 parent reviews on independent sites (we publish verified reviews at /reviews/). Note recurring themes, both positive and negative.

During the tour

  • Ask to see a regular classroom in session, not a showcase room set up for visitors.
  • Ask to talk to a teacher in your child's year group. Their tone tells you more than the head's pitch does.
  • Ask the head: "What is the single biggest area of improvement the school is working on?" The answer reveals candour.
  • Ask about teacher turnover, contract length, and the average tenure of senior leadership. Stable schools talk freely about this; unstable ones deflect.
  • Watch the children moving between lessons. Do they look engaged, calm, friendly to each other, comfortable with adults? You can learn more in 10 minutes of corridor watching than in an hour of presentation.

After the tour

  • Within 24 hours, write down five things the school did well and three things you wondered about. Compare across schools when the file is full.
  • Ask to meet a parent (the school will usually offer one). Ask the parent: "Knowing what you know now, would you choose this school again?" Listen to the silence as much as the answer.

The 12-month admissions timeline

Across most international school cities, families who move smoothly tend to follow this rhythm. Adjust earlier or later based on your destination's admissions cycle (Singapore is the strictest, Dubai is rolling, Geneva opens in January).

12 months out: Decide the destination. Shortlist 2 to 3 cities. Read our city guides for fees, schools, neighbourhoods.
9 months out: Tour 4 to 6 schools (in person where possible, video tours otherwise). Submit applications. Pay registration fees.
6 months out: Receive offers. Accept best fit. Pay first-term deposit. Begin visa, banking, insurance.
3 months out: Confirm housing within commute. Notify current school. Start telling children.
1 month out: Pack and ship. Final school records collected. First-month air-courier box prepared.
Move week: Land, register, settle. Visit the school to finalise enrolment, uniforms, bus arrangements.

Four traps to avoid

Trap 1: chasing the brand. The "best" school in a city is rarely the best for your specific child. The wait-list at the top-tier school is usually 18 months long; the second-tier school three streets away may have stronger pastoral care, smaller classes, and equivalent university outcomes for your child's profile. Tour both. Read our Singapore school shortage piece for a worked example.

Trap 2: optimising for university outcomes you cannot predict. Most parents we speak to are choosing a school for a 6-year-old child whose university interests will not crystallise for another 10 years. Picking a school because its current Year 13 cohort sent 40 students to Russell Group universities is choosing on a snapshot. Pick on the school's culture and approach to learning; the university outcomes follow.

Trap 3: ignoring the commute. The school 45 minutes away across rush-hour traffic will produce a tired, irritable child every evening for years. The school 10 minutes away with one fewer ribbon on its wall will produce a child with two extra hours of family time, sleep, and creative play every day. The right answer is almost always closer than your shortlist suggests.

Trap 4: locking in before visiting. If you can possibly afford the time and money, visit at least three of your shortlisted schools in person before paying a non-refundable deposit. The signals you receive in person, walking the corridors, watching the children, smelling the lunch, are not available in any brochure or video tour.

The final decision framework

Once you have toured, read the inspection reports, talked to parents, and modelled the fees, the decision usually clarifies itself. If it doesn't, this three-question framework helps:

  1. Which school best fits the child you actually have, today, in 2026, with their current strengths and challenges? Not the child you imagine they will be in five years.
  2. Which school has the strongest faculty stability and senior leadership? A school is mostly its teachers. Stable faculty matters more than facility upgrades.
  3. Which school would you choose if money were not a factor, and which would you choose if money were the only factor? The right answer is usually somewhere between, and that gap tells you what you are buying.

If you remain genuinely undecided after that, default to the school with the shorter commute, the more candid head, and the parent body you would want as friends. None of those are quantified on a brochure, and all of them matter more than the marketing.
