I started ExpatSchoolFinder because I was tired of seeing expat families pay €20,000 for private schools simply because they didn't know how to navigate the state bilingual portal. We do the digging so you don't have to.

ExpatSchoolFinder vs Generic Search

Most school information online is outdated, incomplete, or written for a local audience. Here's what makes our data different.

The 3 Pillars of Our Methodology

Every piece of data on this site passes through three verification layers before it reaches you.

Pillar 01

Legislative Monitoring

We track national policy changes in real-time.

Most school directories are updated once a year — if at all. We monitor government gazettes, ministry announcements, and parliamentary records across all 7 countries we cover. When a policy changes, our data changes within days, not months.

Real Example — England 2026

Our 2026 England data accounts for the 20% VAT addition to independent school fees — a change introduced in January 2025 that adds £3,000–£8,000 per year to the average private school bill. Many global directories still show pre-VAT figures.

What this means in practice
  • Ministry of Education announcements tracked weekly
  • Parliamentary legislation monitored across 7 countries
  • Fee changes reflected within 72 hours of official publication
  • VAT, tax relief and subsidy changes fully modelled
Pillar 02

Direct School Outreach

We don't just look at websites.

School websites are marketing materials. They're often out of date, incomplete, and written for a local audience that already understands the system. We contact school secretarias, admissions offices, and cluster directors directly — in the local language — to verify what's actually happening on the ground.

Real Example — Portugal PEBI 2026

For our Portugal guides, we verified the specific PEBI bilingual status for the 2026 cycle at the cluster level (Agrupamentos). Three schools that appeared on the official PEBI list had paused their English-language streams for 2026 due to teacher shortages. We removed them from our recommended list before any family applied.

What this means in practice
  • Direct contact with school secretarias in local language
  • Admissions status verified at cluster level, not just school level
  • English-spoken status confirmed by direct conversation
  • Waitlist and demand levels sourced from admissions staff
Pillar 03

Financial Modelling

Our calculator uses "Total Cost of Ownership" logic.

Schools quote tuition. We quote reality. The true cost of an international school includes registration fees (often non-refundable), mandatory uniforms, school trips, lunch programmes, after-school activities, and "voluntary" contributions that are anything but voluntary. Our calculator models all of these — so the number you see is the number you'll actually pay.

Real Example — Switzerland 2026

A Swiss international school quoting CHF 28,000 tuition typically costs CHF 36,000–42,000 in year one when registration (CHF 4,000), uniform (CHF 800), lunch (CHF 2,400) and mandatory activities (CHF 1,200) are included. Our calculator surfaces this automatically.

What this means in practice
  • Registration and enrolment fees included (often non-refundable)
  • Uniform, PE kit and mandatory equipment costs modelled
  • Lunch, transport and after-school care included
  • "Voluntary" contributions and building levies included

What we don't do

Methodology pages usually only tell you what a company does well. Here's what we deliberately don't do.

We don't accept paid school listings

Schools cannot pay to appear higher in our results or be featured in our guides. Our rankings are based solely on verified data.

We don't use AI to generate school data

All fee data, contact information and programme status is verified by humans through direct outreach — not scraped or AI-generated.

We don't leave data to go stale

We remove schools from our guides when we can't verify their current status. An outdated listing is worse than no listing.

We don't cover countries we haven't verified

We only publish guides for countries where we have direct verification capacity. We'd rather cover 7 countries well than 30 countries poorly.
