How to Choose an International School in Portugal (2026 Guide)
A framework used by Raising Kids in Portugal with 200+ expat families
Choosing an international school in Portugal is one of the most consequential decisions expat families make — and one of the most stressful. With four major international schools within 45 minutes of Lisbon, each with different curricula, admission processes, and cultures, the choice is far from obvious.
1. Step 1: Align curriculum with your long-term plan
The most common mistake is choosing a school based on reputation alone without considering where your children will study next. If you plan to return to the UK, St. Julian's British curriculum (IGCSEs + IB Diploma) maintains the smoothest transition. If you are American or plan to apply to US universities, CAISL or TASIS Portugal's American curriculum is a natural fit. For maximum flexibility, the IB Diploma — offered by all four leading schools — is universally recognised.
2. Step 2: Calculate the real cost of fees
Annual tuition is only part of the picture. Registration fees (€1,000–3,000 one-time), transport, uniforms, and extra-curricular activities typically add 15–25% to the headline fee. At St. Julian's, for example, families frequently budget €20,000–22,000 all-in versus the advertised €16,000–26,000 range. Ask every school for a full-cost breakdown before comparing.
3. Step 3: Visit before you commit
Every school in our guide has been visited by a Raising Kids in Portugal consultant at least 3 times. The difference between a school's marketing materials and its actual atmosphere can be significant. Request a shadow day — where your child attends classes for a full morning — before signing any enrolment contract. Acceptance rates as low as 8% (St. Julian's) mean you should apply to 2–3 schools simultaneously.
