International Schools in Lisbon: A Guide for Globally Mobile Families

Lisbon has become one of Europe's most sought-after bases for internationally mobile families. Mild climate, safety, good connectivity and a relatively affordable cost of living have drawn professionals, entrepreneurs and remote workers from across the world — and the city's international-school sector has expanded quickly to meet the demand, with several new English-medium campuses opening since 2020.

This hub guide gives you the overall map: how Lisbon's international schools are organised by curriculum and location, what to expect on fees and admissions, and where to go next for detail. It is written for families relocating from anywhere, not only from Britain — Global Investments works with internationally mobile clients worldwide, and education is one of the first questions most families ask.

Why Lisbon for an international education?

Lisbon offers an unusually broad choice of curricula for a city its size. Families can keep continuity with a British, American, IB or bilingual pathway, which matters enormously when a child has already moved once or twice. Class sizes are generally modest, English is widely spoken among staff and students, and most schools are used to mid-year arrivals.

The schools cluster in a few areas. The coastal corridor west of the city — Oeiras, Carcavelos, Estoril and Cascais — holds many of the long-established names, drawn by greener space and proximity to the sea. Sintra, inland to the north-west, is home to the city's main American school. Within Lisbon itself, Restelo and Belém in the west and Parque das Nações in the east have become hubs for newer campuses. Our companion guide on the best areas in Lisbon near international schools covers the trade-offs in detail.

The main curricula

Several schools blend systems — for example offering a British primary programme that feeds into the IB Diploma, or a US diploma sat alongside the IB. Our guides on British schools in Lisbon, IB schools in Lisbon and GCSEs and A-Levels in Lisbon go deeper on each route.

A snapshot of established schools

• St. Julian's School (Carcavelos) — the oldest British school in Portugal, founded in 1932, offering the British curriculum, the IB and a Portuguese section for ages 3–18.
• Carlucci American International School of Lisbon (CAISL, Sintra) — a US-style programme from PreK to Grade 12, with both a high-school diploma and the IB Diploma.
• St. Dominic's International School (São Domingos de Rana, near Cascais) — a long-established full IB continuum school (PYP, MYP, DP).
• The British School of Lisbon — English National Curriculum with Cambridge IGCSE and A-Levels, across central and Restelo campuses.
• United Lisbon International School (Parque das Nações) — a modern campus opened in 2020 running the IB programmes in English.
• Redbridge School (Campo de Ourique / Tapada da Ajuda) and PaRK International School — bilingual and IB-influenced options within the city.

New entrants continue to appear — The Lisboan, for instance, opened in central Lisbon in September 2025 on the Cambridge curriculum. Because the landscape changes year to year, treat any list (including this one) as a starting point and verify current details with each school.

Choosing between the curricula in practice

The table above tells you what each route leads to. What it cannot tell you is which route suits your family, and that turns almost entirely on one question: how likely is another move, and when?

A family that expects to stay in Portugal until the end of schooling has the widest choice, because portability barely matters. A family on a defined posting that will end mid-secondary should think harder. Moving between systems is manageable at the middle-school stage, when British, IB and American programmes all have broadly equivalent provision. It becomes markedly harder once a child has started a two-year sixth-form or Diploma programme, and it is genuinely disruptive in the final year of either. Families who think a move is possible during the upper years are usually better served by raising it with the school's guidance staff before they enrol rather than after.

The second question is what the child is like. The British route asks a student to specialise early and go deep in a small number of subjects, which suits a child who already knows what they want to read at university. The IB keeps a broader spread and adds compulsory core components, which suits a well-rounded student but can penalise one who struggles with a required subject group. The American route works best where the likely destination is North America. None of these is a better qualification than the others; they are different shapes, and the fit is individual. Our comparison of the British, IB and American curricula sets the three side by side.

The bilingual and dual-pathway route

The table gives the bilingual option a single line and moves on, which does it a disservice, because it is the route most families dismiss before understanding what it is for.

A dual-pathway school teaches towards a Portuguese qualification alongside an international one, or runs a Portuguese section beside an English-medium one — St. Julian's has operated exactly that arrangement for decades, and schools such as Redbridge and PaRK are built around the bilingual idea from the outset. The label covers a wide range, from Portuguese as a well-taught subject to genuine dual-language instruction; our primary schools guide sets out how to tell them apart when a school describes itself.

What the serious version buys is a kind of optionality the English-medium schools cannot offer. A child who leaves Portugal at fourteen loses nothing except a second language they will keep. A child who stays has a route into the Portuguese system and to Portuguese universities that an English-only pathway does not open in the same way — international qualifications are recognised, but they are recognised through an equivalence process, which is not the same as arriving with the qualification the system was built around. For a family whose plans are genuinely undecided, and that describes a great many of the families who move to Lisbon, the flexibility is worth more than certainty in either single direction.

What it costs is timetable and effort. Two languages of instruction is more demanding than one, and it is a poor choice for a child already struggling, arriving late, or carrying an unmet learning need. It is also harder to enter with age: a school can bring a nine-year-old into learning through Portuguese far more readily than a fourteen-year-old.

So the question to put to a bilingual school is not whether the programme exists. It is up to what age they will still take a child into it, and what happens to a child who cannot keep pace on the Portuguese side — whether there is a route back to a single-language pathway within the same school, or whether it would mean moving again.

Established schools and newer campuses

Lisbon's rapid growth as a destination has produced something genuinely useful — more places, more choice, and more competition on fees — alongside something that deserves care. A school that opened recently has no leavers, no university destination record and, often, no full senior school yet. That is not a reason to avoid it. Newer campuses frequently have better facilities, smaller classes and a stronger appetite to accommodate arriving families. It simply means the evidence you can gather is different.

For an established school, ask for results and destination data and press on what the numbers exclude. For a newer school, ask instead about the things that predict how it will turn out: the head's background and how long they have committed, whether the school is accredited or working towards accreditation and by whom, whether the senior years are actually staffed or merely planned, and what happens to your child if the sixth form does not open on the timetable advertised. Ask also who owns the school and how it is financed, because a young school with a thin roll is a business as well as an institution.

Sequencing a school search from abroad

Families who run into difficulty in Lisbon usually do so because the steps happened in the wrong order. A workable sequence looks like this. Shortlist on curriculum first, since that constrains everything else. Establish availability in your child's exact year group second, because a school that is excellent and full is not an option. Only then let location enter the decision, and only then commit to a lease or purchase — the coastal corridor, Sintra and the city districts are far enough apart that a school chosen after the home has been signed for can mean a long daily commute for years.

Applications to more than one school are normal and expected here, not a discourtesy. Assessment and documentation requirements are set out in our how to apply guide, and the realities of waiting lists are covered separately.

The cost behind the fee

Fees vary widely by school and year group. As a broad 2025/26 guide, expect annual tuition somewhere between roughly €6,000 and €30,000 — and treat that published figure as where a budget starts rather than where it ends, because our structured breakdown in the international school fees in Lisbon guide shows how much sits outside it. Registration and assessment fees are frequently non-refundable, deposits are usually payable on acceptance, and capital or building levies may sit outside tuition entirely. Transport, lunches, uniform or kit, technology, trips and activities recur every year, and external examination entries land in the senior years when tuition is already at its highest. Fees also tend to rise annually and to step up with year group, so a family with two children moving through the school at different stages should expect a peak period rather than a flat commitment.

Because most families in Lisbon do not earn in euros, there is a currency question layered on top. Fees are a known, recurring liability in a specific currency, which makes them unusually suited to being planned rather than absorbed. Holding a euro balance, matching some savings to the fee currency, or fixing a rate ahead of a payment already committed are all approaches families use; our guides to international school fee planning and currency risk management cover the mechanics. The value of investments set aside for fees can fall as well as rise, and exchange rates move both ways.

Settling in

Choosing a school is only the first step. Children also need to adjust to a new country — the school year runs September to June, Portuguese is taught even in English-medium schools, and families must register for healthcare and residency. Our guide on settling your child into school in Lisbon covers the practical side, and for older students our university admissions guide explains UCAS, EU and Portuguese routes.
