Schools in the Margem Sul — A Guide for Families
International, Portuguese, and alternative schools for families living south of Lisbon.
Choosing the right school is one of the biggest decisions for families relocating to Portugal. The Margem Sul offers more options than most people realise — from internationally recognised schools with Cambridge and IB curricula to excellent Portuguese private schools (colégios), forest schools, Waldorf education, and a strong public system that's free from age 6 to 18. Whether you're looking for an international school in Setúbal, a bilingual school in Seixal, or a Portuguese colégio in Almada, this guide covers what's available, what it costs, and how to decide which path is best for your children.
If your children need English-medium education through to university entrance, St. Peter's International School in Palmela is the most established option, offering both Cambridge IGCSE and the IB Diploma. For younger children, Almada International School and Seixal International School offer excellent bilingual Cambridge education in smaller, more intimate settings. Note that Almada International School is still expanding — check their current age offering when you enquire.

When families relocate to Portugal, the default assumption is usually "international school." And for some families — particularly those with older teenagers or those who may only stay a few years — that's the right call. But for families planning to make the Margem Sul their long-term home, Portuguese schools — both private colégios and the public system — deserve serious consideration.
Here's why:
Children learn Portuguese fast. Young children aged 3 to 10 typically become fluent in Portuguese within 6 to 12 months of immersion. They absorb the language naturally through play, friendships, and daily school life. By the end of their first year, most are indistinguishable from their Portuguese classmates in terms of language ability.
True bilingualism is a gift. If you speak English at home and your child attends a Portuguese school, they grow up genuinely bilingual — not just "school bilingual" with a second language studied in class, but deeply fluent in both languages and cultures. This is an extraordinary advantage that an international school, where English dominates, can't replicate to the same degree.
Cultural integration matters. Children who attend Portuguese schools make local friends, understand local culture from the inside, and develop a sense of belonging in their community. This makes an enormous difference to the whole family's experience of life in Portugal — your social network grows through your children's friendships and school events.
The quality is better than you think. Portugal's PISA scores now sit above the EU average. The public system is free and compulsory from 6 to 18, and the best Portuguese private schools consistently deliver excellent academic results. Colégio Campo de Flores in Caparica, for example, regularly ranks in the top 20 nationally.
The cost difference is significant. Portuguese private schools typically charge €400–500 per month. International schools start at €800+ per month and can exceed €1,000 for upper secondary. Public schools are free. Over 12 years of education, this adds up to tens of thousands of euros.
The caveat: Older children (aged 14+) who arrive with no Portuguese will struggle with immersion, particularly if they need to sit exams within a year or two. For teenagers, an international school with English-medium teaching may be the more practical option. For younger children, the immersion route is almost always worth it.
Why Portuguese Schools Deserve Serious Consideration
Most expat guides only list international schools. Here's why that's a mistake.
Portuguese private schools follow the national curriculum, which means all teaching is in Portuguese. For expat families, this is either the biggest advantage (full immersion and integration) or the biggest challenge (language barrier in the early months). Most schools are welcoming to foreign families and will support children through the transition — but it's worth visiting the school and discussing your child's specific situation before enrolling.
Best Portuguese Private Schools (Colégios) in the Margem Sul
These are the melhores colégios in the region — offering excellent education at a fraction of international school fees.
Alternative schools in the Margem Sul mostly serve younger children (up to age 12). For older children, families typically transition to a mainstream Portuguese or international school. These schools often work well as a complement — for example, Escola Lá Fora's afterschool and holiday programmes can be combined with a conventional school for children aged 3 to 12.
Forest Schools, Waldorf & Alternative Education
For families who want a different approach — nature-based, child-led, and creative.
The public system is taught entirely in Portuguese. For expat children, schools may offer additional Portuguese language support (Português Língua Não Materna — PLNM), though the availability and quality of this varies by school and area. In the Margem Sul, the best-performing public secondary schools include Escola Secundária Emídio Navarro and Escola Carlos Gargaté, both in Almada.
Registration for public schools is done through your local agrupamento de escolas (school cluster). You'll need your child's NIF, proof of address in the school's catchment area, and vaccination records. The academic year runs from September to mid-June.
