International schools are the premium tier of ESL teaching — offering the highest salaries, best benefits, and most professional environments. But they also have the strictest qualification requirements. Unlike language schools that hire TEFL-certified graduates, international schools typically require licensed teachers with formal qualifications. This guide explains exactly what you need to land a job at an international school.
International Schools vs Language Schools: What’s the Difference?
Before diving into requirements, it’s important to understand what international schools are:
- Language schools (hagwons, academies, buxibans) — After-school programs focused on English language acquisition. Hire TEFL-certified teachers. Lower pay, higher turnover.
- International schools — Full-curriculum schools (K-12) serving expatriate and wealthy local families. Teach all subjects in English (often IB, British, or American curriculum). Hire licensed teachers. Higher pay, professional environment.
International schools aren’t really “ESL teaching” in the traditional sense — they’re mainstream teaching in an international setting. But many ESL teachers transition to them as a career upgrade.
The Core Requirement: A Teaching License
The single most important qualification for international schools is a valid teaching license or qualification from your home country. This means:
For US Citizens
- A state-issued teaching license/certificate
- Typically requires a degree in education + student teaching experience
- Subject-specific endorsements (e.g., licensed to teach elementary, or secondary English)
For UK Citizens
- Qualified Teacher Status (QTS)
- Typically via PGCE (Postgraduate Certificate in Education) + induction year
For Other Countries
- Equivalent home-country teaching qualification
- Must be recognized as equivalent to a full teaching credential (not just a TEFL)
A TEFL certificate is not a substitute for a teaching license at international schools.
Full Qualification Profile
To be competitive for international school positions, you typically need:
Essential
- Bachelor’s degree — Preferably in education or your teaching subject
- Teaching license/qualification — From your home country (state license, QTS, etc.)
- 2+ years of post-qualification experience — Most schools require experience teaching in a formal school setting
Preferred
- Master’s degree — Particularly in education, your subject area, or educational leadership
- Experience with international curricula — IB (PYP, MYP, DP), Cambridge IGCSE/A-Levels, Advanced Placement
- ESL/EAL endorsement — If you’ll be teaching English language learners
- Special education qualification — In demand at many schools
For ESL/EAL Specialist Roles
If you’re applying specifically as an English as an Additional Language (EAL) specialist:
- Teaching license plus ESL endorsement or certification
- Master’s in TESOL or Applied Linguistics (highly preferred)
- Experience teaching ESL in a school setting
What International Schools Offer
The reason teachers aim for international schools is the compensation package:
- Salaries: $2,500–$5,000+/month (varies widely by region)
- Housing: Free or heavily subsidized
- Flights: Annual return flights home
- Insurance: Comprehensive health insurance
- Retirement: Some offer pension contributions or end-of-contract bonuses
- Education for dependents: Free or discounted schooling for your children
- Professional development: PD budgets for conferences and courses
- Shipping allowance: For relocation
Salary Ranges by Region
| Region | Monthly Salary (USD) | Savings Potential |

The Hiring Calendar
International schools follow a different hiring timeline than language schools:
- September–November: Schools begin advertising positions for the following academic year
- November–February: Peak hiring season (interviews and offers)
- March–June: Late vacancies and replacements
- August: Start of the academic year (most schools)
If you want a position starting in August, you should be applying by November of the previous year.
Where to Find International School Jobs
- School websites — Most international schools post vacancies on their own sites
- Search Associates — Prestigious recruitment service (application required)
- Schrole / ISS — Database-driven recruitment platforms
- TES (Times Educational Supplement) — Strong for British-curriculum schools
- CIS (Council of International Schools) — Recruitment fairs worldwide
- Recruitment fairs — Held in London, Dubai, Bangkok, and other hubs, typically Jan–Feb
How ESL Teachers Can Transition to International Schools
If you’re currently teaching at a language school and want to move up:
- Get licensed — This is non-negotiable. Most accessible routes: US alternative certification programs, UK PGCE via assessment, or iPGCE (international PGCE).
- Gain formal school experience — Volunteer, substitute, or take a role at a school back home.
- Get a master’s — An MA TESOL, MA Education, or subject-specific master’s makes you competitive.
- Learn IB or Cambridge curricula — Take introductory workshops.
- Start at lower-tier schools — Tier 2 and 3 international schools have more flexible requirements and can be a stepping stone.
Tiers of International Schools
Not all international schools are equal:
- Tier 1: Elite, highly selective, top salaries. Require master’s + extensive experience. Examples: Singapore American School, Tanglin Trust (Singapore).
- Tier 2: Solid, established schools. Require licensed teachers with 2+ years experience. Most realistic target for first-time international teachers.
- Tier 3: Newer or less resourced schools. May accept newly qualified teachers. Good entry point but verify quality.
- Bilingual schools: Local curriculum taught partly in English. Lower pay, different expectations.
Red Flags at International Schools
Even at the higher end, some schools have problems:
- High staff turnover (check forums like ISR — International Schools Review)
- Salary paid late or in devaluing local currency
- Curriculum changes that make teaching difficult
- Unsupportive or absent leadership
- “Bait and switch” on contract terms
Always research schools through ISR, teacher forums, and direct contact with current staff.
The Bottom Line
International schools are the premium career path for English-speaking educators abroad — but they require formal teaching qualifications, not just a TEFL. If you’re a licensed teacher with experience, they offer the best compensation and professional environment in the ESL world. If you’re an ESL teacher without a license, the path requires getting licensed first, but the long-term payoff is significant.
