International Schools in and Around Lisbon, Cascais & Sintra: Fees, Curricula, and How to Choose

The curricula landscape — which system leads where

Before any conversation about a specific school, it helps to be clear about the five systems on offer, because the curriculum is the one decision that follows your child for years and is the hardest to undo mid-stream.

British (the National Curriculum for England). The largest English-medium offer in the Lisbon area. Children follow the English curriculum, sit IGCSEs or GCSEs around age 16, and then typically choose between A Levels and the International Baccalaureate Diploma in the final two years. St. Julian's School in Carcavelos and IPS Cascais British International School in Alcabideche are both built on the English curriculum; St. Julian's takes children from age 3 to 18 and then offers the IB Diploma or Career-related Programme in Years 12 and 13, alongside a separate bilingual pathway built on the Portuguese national curriculum. This British-then-IB shape is common in Portugal and worth understanding early, because it changes what the final two years look like.

American. A US-style programme, usually following a defined curriculum sequence through the grades and culminating — at the schools here — in the IB Diploma rather than US Advanced Placement alone. Carlucci American International School of Lisbon (CAISL) in Sintra and TASIS Portugal, also in the Sintra area, both sit in this family; both publish an American programme that runs through to the IB Diploma, with Cambridge IGCSE in the middle years. For a family moving from the United States, or one that wants a recognisable US rhythm to the school year, this is the natural starting point.

International Baccalaureate (IB). The IB is less a "nationality" and more a framework that several of the schools above plug into for the final years — but it is worth naming on its own, because some families specifically want the IB Diploma for its global university recognition. United Lisbon International School, in central Lisbon, runs an international programme through to the IB Diploma in Grades 11 and 12. If portability between countries is your priority — because you may move again — an IB finish is often what families are really asking for, whatever flag is over the door.

French. Portugal has a long-established French school serving the lycée network. The Lycée Français Charles Lepierre in Lisbon teaches the French national curriculum from maternelle through to the Baccalauréat, within the AEFE network of French schools abroad. For French families — and for any family wanting genuine French-language schooling with a clear path back into the French system — this is the reference point, and as you will see below, its fees sit well under the English-medium schools.

German. The Deutsche Schule Lissabon (Escola Alemã de Lisboa), one of the oldest German schools abroad, teaches the German curriculum through to the Abitur, with campuses in Lisbon and in Estoril. As with the French lycée, it serves a specific national community first but is open more widely, and its fees are closer to the French school's level than to the English-medium schools'.

Bilingual and Portuguese-international. Several of these schools also run bilingual streams on the Portuguese national curriculum — St. Julian's bilingual pathway is one example — which can be a deliberate choice for families who expect to stay long-term and want their children fully fluent and integrated, not in an English-speaking bubble. It is a genuinely different strategy from the international-track schools, and a good one for the right family.

Good to know. "International school" is not a regulated label that guarantees a particular curriculum. Two schools can both call themselves international and run completely different systems — British versus American versus IB — with different exams, different term structures and different university destinations. Always check which curriculum a school actually delivers in the final years, on the school's own academics page, before anything else.

The Cascais–Estoril–Sintra "school belt"

If you draw a line west from Lisbon along the coast and the Sintra railway, you pass through the densest concentration of international schooling in Portugal. Locals and long-term international families just call it the school belt, and it explains a lot about where foreign families end up living.

Carcavelos. A coastal town on the Cascais line, roughly between Lisbon and Cascais proper, and home to St. Julian's School — the oldest British international school in the country, on its Quinta Nova campus on Avenida Jorge V. Carcavelos has a beach, a train station with a direct line into Lisbon and out to Cascais, and a settled, family-heavy feel; the school's presence is part of why.

Estoril. The genteel resort town just before Cascais, on the same line. It hosts a campus of the Deutsche Schule Lissabon, in addition to the school's main Lisbon site — so German-schooling families often look here rather than in the city.

Cascais and Alcabideche. Cascais itself is the anchor of the western end — a former fishing town turned smart coastal hub — and just inland, in Alcabideche, sits IPS Cascais British International School, a British-curriculum school established in 1982. Families who want the Cascais lifestyle but a smaller, more local British school often look here.

Sintra (Linhó). Inland and uphill, around the Linhó area near Sintra, you find the two American-tradition schools close together: Carlucci American International School of Lisbon (CAISL) and TASIS Portugal. This is greener, calmer, more suburban-in-the-hills than coastal — and it tends to suit families who prioritise space and the school over walkable town life.

The practical upshot is that the belt is not one place but a string of quite different towns sharing a railway and a motorway — and which one suits you depends heavily on which school you are aiming at, because the daily school run is the single journey you cannot avoid.

A note from doing this with families. The Cascais line is convenient, but "on the line" and "a sensible school run" are not the same thing. A house three stations from the school, or up in the Sintra hills when the school is on the coast, can mean a very long morning twice a day. We always map the actual door-to-gate journey before anyone falls in love with a house.

The schools in central Lisbon

Not every family wants the coast. For those who want to live in the city — for work, for lifestyle, or because city life is the point of the move — central Lisbon has its own international options.

United Lisbon International School (ULIS) sits in the city (Avenida Marechal Gomes da Costa, in the east of Lisbon), runs an international programme to the IB Diploma, and is part of the Dukes Education group. It is one of the newer, purpose-built international schools and a common choice for families who want to be in Lisbon rather than out on the line.

Lycée Français Charles Lepierre is also in Lisbon, serving the French curriculum to the Baccalauréat, and Deutsche Schule Lissabon has its main campus in the city as well (with the Estoril campus described above). So two of the three national-system schools are city-based, which matters if you want French or German schooling without committing to the coast.

There are further bilingual and international schools across the wider Lisbon area beyond those named here — for example, PaRK International School, a bilingual-then-Cambridge/IB group with campuses in and around Lisbon (Alfragide, Praça de Espanha and Restelo) — and the landscape shifts as schools open and expand. The point of this guide is the shape of the choice and the towns it maps onto, not an exhaustive directory; for any school you are seriously considering, the school's own admissions team is the only reliable source on places, fees and curriculum.

What the schools actually publish for fees

Fees are where families most want a straight answer and most often get a vague one, so here is the discipline we apply: every figure below is taken from the named school's own published fee or admissions page, and dated to when we checked it (10 June 2026). Where a school does not publish a number — several only release fees on application or via an enquiry form — we say so rather than guess. Do not treat these as quotes for your child; they are list figures that change yearly, exclude many extras, and are no substitute for a current invoice from the school.

A few patterns hold across the market:

• English-medium schools are the most expensive. At the schools that publish, annual tuition at CAISL for 2026/2027 runs from around €12,128 at Early-Childhood and Kindergarten level to about €23,532 a year for the senior grades (Grades 9–12), per its own fee schedule. TASIS Portugal publishes 2026/2027 annual tuition from roughly €13,007 in pre-kindergarten up to about €24,308 a year in Grades 11–12. United Lisbon publishes 2026/2027 annual tuition rising from about €12,390 in Pre-K3 to €25,200 a year in Grade 12. These are the upper end of the market.

• The French and German schools are substantially cheaper, reflecting their state-supported, community-school model. The Lycée Français Charles Lepierre publishes 2026/2027 annual fees from about €6,098 a year for the youngest classes (for French, Portuguese and EU-citizen families) up to roughly €8,286 a year for the upper school at the non-EU rate. The Deutsche Schule Lissabon publishes annual tuition (Schulgeld) for 2025/2026 of roughly €8,141 to €9,238 a year depending on the section and campus. Both are a different order of cost from the English-medium schools.

• Several schools publish fees only on application. St. Julian's School publishes its fee schedule on its own admissions pages but as charts you request rather than a single quotable figure, so we leave its tuition as on application here and point you to the school. IPS Cascais releases its detailed pricing via an enquiry form (fees on application), and PaRK International School publishes per-campus fee documents you download — again, treat these as published on application and get the current sheet from the school.

• The headline tuition is never the whole bill. Most schools add one-off registration or enrolment fees and, at several, a capital or building fee — for example, CAISL lists a building fee of €1,953 per year (for the first five years) and a one-time registration fee of €600 per child, and TASIS lists a one-time campus enhancement fee, both on their own fee pages. Lunch, transport, after-school care, uniform and external exam fees are typically extra. Always read the school's fee page in full, not just the tuition line.

Good to know. The cheapest published number you see for a school is almost always the youngest year group. Fees step up materially as children get older — the senior-school figure can be roughly double the early-years figure at the same school — so if you have a young child, budget for the trajectory, not just year one.

Waiting lists, registration timing and the calendar

This is the part that catches families out, because it runs on a clock that has nothing to do with your move date.

Popular year groups fill. The most-requested schools and the most-requested entry points (often the start of primary, and the start of secondary) can have limited places and waiting lists, especially for a mid-year arrival. Several schools, including United Lisbon and CAISL, operate rolling or year-round admissions in principle — but "we accept applications year-round" is not the same as "there is a seat in Year 4 this February." Availability is specific to the year group and the moment.

Registration is a sequence, not a single step. Across these schools the pattern is consistent: an enquiry, a visit or assessment, an application with a non-refundable application fee, an offer, and then enrolment secured by a further fee within a set window (United Lisbon, for instance, asks for enrolment to be confirmed within ten working days of an offer). Each stage takes time, and the assessment can require school transcripts from the previous two years — which you need to gather before you start, not after.

Re-registration locks up returning families early. Many schools ask existing families to re-register for the next year as early as February, which is when the true picture of free places for new joiners firms up. Practically, that means the best information about September availability often does not exist until the spring before.

The plain summary: start the school conversation as early as you possibly can, run it in parallel with your visa and housing rather than after them, and treat a confirmed school place as a fixed point you build the rest of the move around.

What really drives the cost

If you are comparing schools, it helps to know what you are actually paying for, because the differences are not random.

• Curriculum and exam board. The English-medium, IB-finishing schools sit at the top of the market; the state-supported national schools (French lycée, German school) are materially cheaper because of how they are funded and structured, not because they are lesser.
• Age and year group. Within any one school, fees rise with age — early years is the cheapest entry point, senior school the most expensive.
• One-off and annual add-ons. Registration and enrolment fees, and capital or building levies where they apply, can add meaningfully to the first-year bill in particular.
• The extras. Lunch, door-to-door transport, after-school care, uniform, school trips and external examination fees are commonly billed on top of tuition. On the Cascais line especially, transport can be a real line item if you live a few towns from the gate.
• Siblings. Most schools offer sibling discounts, typically from the third child — useful for larger families to factor in.

None of this is exotic, but it adds up, and the published tuition figure is only ever the starting point. Build your budget from the school's full fee page and add a realistic allowance for the extras your family will actually use.

How the school decides where you live (not the other way round)

Here is the single most useful idea in this whole guide, and the one we most often have to talk families through: for a family with school-age children, the school place usually comes first, and the home follows it.

The reason is simple. You can change a lot about a move — the exact flat, the furniture, even the town — far more easily than you can move a child between curricula or wait out a waiting list. So once a school is chosen and a place is offered, that gate is effectively a fixed point on the map, and the sensible next questions are: what is a humane daily journey to it, what does that do to my housing options and budget, and does the rest of the move still work from there?

In practice that means:

• If you are aiming at the Sintra schools (CAISL, TASIS), you are likely looking at the greener, more suburban areas inland and around the line's western reaches — a different lifestyle, and often different housing stock, from the coast.
• If you are aiming at Carcavelos, Estoril or Cascais (St. Julian's, IPS Cascais, the German school's Estoril campus), you are in coastal-town territory, with the Cascais line as your spine and a premium on anything within an easy run of the gate.
• If you are set on a city school (United Lisbon, the French lycée, the German school's Lisbon campus), then central Lisbon neighbourhoods are in play, and the calculation becomes about commute, space and city budgets instead.

This is exactly where the home search and the school search have to be run as one project, not two — and where renting first, before committing to a purchase, often makes sense, so you can confirm the school place and the daily reality before you buy. We cover the mechanics of both renting a home in Portugal and buying a home with a buyer-only advisor, and the broader picture in our complete guide to buying property in Portugal as a foreigner. For the wider settling-in — the home set up around the school and the daily life — see how we help families settle in once you've arrived. And because the school move sits on top of a visa, the route you are coming on shapes the timeline too; we set out the visa routes that bring families to Portugal separately.

Good to know. Fees are only one side of the budget. Housing, transport and the wider costs of a purchase — set out in the hidden costs of buying property in Portugal — all shift depending on whether you land on the coast, in the Sintra hills, or in the city, and the school you choose nudges that decision more than almost anything else.

Frequently asked questions

Which international schools are in the Lisbon, Cascais and Sintra area? The most-chosen schools cluster along the Cascais line and in central Lisbon. On the "school belt" you'll find St. Julian's School (British, Carcavelos), IPS Cascais British International School (British, Alcabideche), and the American-tradition CAISL and TASIS Portugal (both in the Sintra/Linhó area), plus the Deutsche Schule Lissabon's Estoril campus. In the city are United Lisbon International School (IB), the Lycée Français Charles Lepierre (French), and the Deutsche Schule Lissabon's main campus (German). Several other bilingual and international schools, such as PaRK International School, sit across the wider Lisbon area.

What curricula do they teach? The main systems are British (the English National Curriculum, leading to IGCSE/GCSE and then often the IB or A Levels), American (typically finishing with the IB Diploma at the schools here), the International Baccalaureate, French (to the Baccalauréat, at the lycée), and German (to the Abitur). Some schools also run bilingual streams on the Portuguese national curriculum. Always confirm the exact curriculum on the school's own academics page.

How much do international schools in Lisbon cost? It varies widely by school and age. From schools that publish, 2026/2027 annual tuition at the English-medium and IB schools ranges roughly from the low teens of thousands of euros in the early years up to about €23,000–€25,000 a year in senior school (for example CAISL, TASIS Portugal and United Lisbon, per their own fee pages). The French and German schools are substantially cheaper — roughly €6,000–€9,000 a year, per their own pages. Some schools publish fees only on application. Every figure here is a list price that changes yearly and excludes many extras.

Do international schools in Portugal have waiting lists? Popular year groups and entry points can be full, with waiting lists, especially for mid-year arrivals — even at schools that run year-round admissions. Returning families often re-register as early as February, so the true picture of free places for new joiners typically firms up only in the spring before a September start. Start early.

Should I choose the school or the neighbourhood first? For a family with school-age children, the school usually comes first. A confirmed place is hard to move; a home is comparatively easy to choose around it. Once you know the school, you can work out a humane daily journey and which towns and budgets that implies — which is why the home search and the school search should be run together.

Can my children attend a Portuguese state school instead? Yes — Portugal has free state schooling, taught in Portuguese, and many international families do choose it, particularly for younger children and for long-term integration. It is a genuinely different path from the international-curriculum schools, with its own trade-offs around language, continuity and university routes, and the right choice depends entirely on your family's plans. This guide covers the international-school landscape specifically; for the state system, your local câmara (municipal council) and the Ministério da Educação are the authorities to consult.

Where this gets personal

That is the landscape: two clusters — the Cascais–Estoril–Sintra belt and central Lisbon — five curricula, fees that run from around €6,000 a year at the state-supported national schools to the mid-twenties of thousands at the English-medium and IB schools, a registration calendar that rewards starting early, and the one rule worth tattooing on the move — for a family with children, the school place tends to decide the neighbourhood, not the reverse.

What no guide can tell you is which of these is right for your family — and that is the part that actually determines your move. It depends on your children's ages and how many years of schooling are left; on curriculum continuity — whether you need a system you can re-enter elsewhere if you move again, which often points to the IB; on your budget, once you've added transport and the extras to the headline tuition; and on which town the right school sits in, because that quietly sets your housing search, your commute and what the whole move costs. Two families with the same nationality and the same budget routinely land on different schools, different towns and different homes — because the children, the timeline and the plans are different.

That is exactly the knot we help families untangle. In a €250 Portugal Path Session, Mia and Rafael sit down with your situation — the ages, the curriculum question, the shortlist of schools, the towns they map onto, the visa you're coming on and the budget it all has to fit — and you leave with a written Path Plan: your route, your order of steps, and where the school place sits in the sequence so the home, the commute and the visa line up around it. If Portugal, or a particular school strategy, isn't the right move for you, we'll tell you — that's part of the session.
