TL;DR: Portugal offers four main schooling paths for expat families: free Portuguese state schools (excellent for younger children and language immersion), private Portuguese schools (middle ground, €3,000–€10,000/year), international schools in Porto (OBS and CLIP, €9,000–€16,000/year), and international schools in Lisbon (St Julian’s, CAISL and others, €12,000–€26,000/year). The right choice depends on your children’s ages, how long you plan to stay, and whether curriculum continuity matters. Most families get this wrong by deciding too late.
The school question is the one that shapes everything else about a move to Portugal. Get it sorted first — where you live, what visa you need, how much the move costs, even which city you choose — all of these decisions flow from what you decide about schools.
We moved to Porto with children. We researched this exhaustively before we came. What follows is the honest version of what we wish someone had told us from the start — not a directory of schools with marketing copy, but a clear framework for making the right decision for your family.
The Four Schooling Paths for Expat Families in Portugal
Most guides present this as a binary: international school or Portuguese state school. In reality there are four distinct options, each with a different cost, profile, and outcome.
Path 1: Portuguese State Schools (Free)
Portugal’s public schools are free, generally well-run, and increasingly experienced with non-Portuguese-speaking children — particularly in Porto and Lisbon where the expat community has grown significantly. They are funded by the state and follow the Portuguese national curriculum, taught entirely in Portuguese.
Annual cost: Effectively free. Some minimal materials fees apply.
Works best for: children under 9–10 who will acquire Portuguese through immersion; families committed to long-term integration; families where budget is a genuine constraint.
The honest reality: For young children, this is genuinely excellent. A 6-year-old entering a Porto state school in September will typically be conversationally fluent in Portuguese by the following summer. We’ve seen this happen. It is remarkable and it is free. For older children and teenagers, the transition is harder — the academic demands of the Portuguese curriculum at secondary level are significant, and arriving without Portuguese is genuinely challenging at 13 or 14.

Path 2: Private Portuguese Schools (€3,000–€10,000/year)
Private Portuguese schools follow the national curriculum but with smaller class sizes, stronger pastoral care, and often enhanced English provision. Some offer bilingual (Portuguese/English) programmes. They are significantly cheaper than international schools and cheaper than many families expect.
Annual cost: approximately €3,000–€10,000 per child depending on school and year group.
Works best for: families who want more English support than a state school provides but don’t need British, American, or IB curriculum continuity; families planning to stay long-term who want their children to integrate properly into Portuguese education; families with a tighter budget than international school fees allow.
The honest reality: This middle path is underused and underrated. Many expat families jump straight from state school to international school without seriously considering private Portuguese schools — partly because they’re harder to research in English. If your children are under 12 and you’re planning a long-term move, a good bilingual private Portuguese school often gives better outcomes at a fraction of the international school cost.
Path 3: International Schools in Porto (€9,000–€16,000/year)
Porto has four established international schools. The two main ones for English-speaking families are OBS (Oporto British School) and CLIP (The Oporto International School). Both teach through English, both offer the IB Diploma, and both have waiting lists. If Porto is your destination, these two schools will dominate your research — we’d recommend visiting both before committing. The atmospheres are noticeably different despite similar fee levels.
| School | Ages | Curriculum | Fees (2025/26) | Location |
|---|---|---|---|---|
| OBS (Oporto British School) | 3–18 | British / IB Diploma | €8,990–€14,585 | Foz do Douro |
| CLIP | 3–18 | British-based / IB Diploma | €9,140–€15,190 | Aldoar / Boavista |
| Lycée Français Porto (LFIP) | 3–18 | French national curriculum | €4,915–€6,214 | Foz do Douro |
| Deutsche Schule Porto | 3–18 | German bilingual | Verify directly | Foz do Douro |
Annual cost (realistic total, including extras): €12,000–€20,000 per child, once uniform, transport, lunch, and activity costs are included.
Works best for: families with older children needing curriculum continuity; families uncertain how long they’ll stay; families where the child needs to maintain British or IB qualifications.
The honest reality: OBS and CLIP are both well-regarded. OBS is smaller and sits closer to the beach in Foz — it has a tight community feel and is the only IB Diploma provider in northern Portugal, which matters enormously for families with children approaching sixth form. CLIP is slightly larger and more internationally diverse. If you can, visit both before deciding. The right school tends to be obvious in person in a way it never is from a website.
One important caveat for Porto: if you need the American curriculum specifically, OBS and CLIP don’t offer it. CAISL (the main American curriculum school) is near Lisbon. This is the single most common reason families choose Lisbon over Porto.

Path 4: International Schools in Lisbon (€12,000–€26,000/year)
Lisbon has a significantly larger range of international schools than Porto — more curricula, more year groups covered, more choice. The main options for English-speaking families:
| School | Ages | Curriculum | Fees approx. | Location |
|---|---|---|---|---|
| St Julian’s School | 3–18 | British / A-levels | €12,000–€20,000 | Carcavelos |
| CAISL | 3–18 | American / IB Diploma | €18,000–€26,000 | Sintra |
| TASIS Portugal | 3–18 | IB all programmes | Verify directly | Quinta do Perú |
| United Lisbon International | 3–18 | IB | Verify directly | Parque das Nações |
| Lycée Français Lisbon | 3–18 | French national curriculum | Verify directly | Lisbon |
Annual cost (realistic total, including extras): €18,000–€35,000+ per child in Lisbon’s premium international schools. For a family with two children at St Julian’s or CAISL, school alone can cost €40,000–€55,000/year.
Works best for: families with specific curriculum requirements (American curriculum families almost always end up in Lisbon for CAISL); families with older teenagers who need specific qualifications; families who want the broadest possible choice.
The honest reality: Lisbon’s school selection is excellent. The cost is also substantially higher than Porto — and that cost gap is the main reason families moving primarily for financial reasons tend to choose Porto. If Lisbon is the right city for your family for other reasons, the schools are genuinely strong.

How to Choose: The Decision Framework
Here is the honest framework we’d use if we were starting again.
Start with age and length of stay
These two variables determine almost everything else.
| Child’s age | Planning to stay long-term | Uncertain / short-term |
|---|---|---|
| Under 8 | Portuguese state school — strongly recommended | Portuguese state school or lower-fee international |
| 8–11 | State or private Portuguese school | International school |
| 12–14 | Private Portuguese or international — discuss carefully | International school |
| 15+ | International school (GCSEs/IB/A-levels) | International school |
Then consider curriculum continuity
If your children are in exam years (GCSEs, A-levels, IB, American diploma) and may need to continue that qualification elsewhere — in Portugal or back in their home country — curriculum continuity is non-negotiable. International school is the answer, and your city choice may follow from which school offers the curriculum you need.
If your children are young and you’re planning to stay in Portugal permanently or semi-permanently, curriculum continuity matters much less. Portuguese education leads to a strong qualification in its own right, and the language acquisition your children gain is genuinely valuable.
Then model the actual cost
The number that matters is not the headline tuition fee — it’s the total annual cost per child including transport, lunch, uniform, and activity fees. For most international schools in Portugal, this adds 20–40% to the base fee. For a family with two children, the difference between state school (free) and international school (€25,000–€40,000/year) is the single largest financial variable in the entire move. Model it honestly before you commit.
Contact schools before you decide anything else
Waiting lists at international schools in Portugal — particularly OBS, CLIP, St Julian’s, and CAISL — are real, and particularly acute at popular year groups (Year 7, Year 10, IB entry). We’ve heard from families who had everything else planned and then discovered there was no place available for their child’s year group at any Porto international school for 18 months.
Contact schools at least 12 months before your intended start date. Register interest as early as possible, even before your application is finalised. The school timeline should drive the move timeline — not the other way around.
The Portuguese School System: Age by Age
For families considering the state or private Portuguese route — or mixing approaches across different children — understanding how the system is structured matters.
- Creche (0–3): Nursery. Not compulsory. Public creches are subsidised but have waiting lists; private creches cost €400–€800/month in Porto. Portuguese immersion at this age is fast and highly effective.
- Pré-Escolar (3–6): Pre-school. Free in state schools from age 3. Play-based curriculum. The optimal entry point for language immersion — children entering at 3–4 typically achieve near-native fluency by age 6.
- 1º Ciclo (6–10, Years 1–4): Primary. Compulsory. Single class teacher. For expat children, this is the stage where immersion works best and adaptation is fastest.
- 2º Ciclo (10–12, Years 5–6): Lower secondary. Subject specialists. A second foreign language is introduced. Later arrivals with no Portuguese find this stage harder.
- 3º Ciclo (12–15, Years 7–9): Upper secondary. Curriculum deepens significantly. Curriculum continuity becomes critical for families who may return home.
- Ensino Secundário (15–18, Years 10–12): Leads to the national Exames Nacionais and university entry. Most expat families at this stage are in international schools.

Language: The Thing Everyone Underestimates
Portuguese is not an easy language for English speakers. The written form looks like Spanish; the spoken form sounds like nothing most English speakers have heard. Children acquire it faster than adults — dramatically faster. A 7-year-old will almost always outpace their parents.
For families using international schools, investing in Portuguese language lessons from day one — for both children and adults — pays dividends in social integration, in daily life, and in the children’s ability to make local friends outside school. International school creates a bubble; Portuguese lessons puncture it in the best way.
For families using state schools, the school handles language acquisition — but supplementary tutoring in the first 6–12 months helps bridge the gap while immersion is still taking hold.

Porto or Lisbon for Schools: The Summary
This question comes up constantly and the honest answer is: it depends on your curriculum.
- British curriculum / IB Diploma: Both Porto (OBS, CLIP) and Lisbon (St Julian’s, TASIS) have strong options. Porto is cheaper.
- American curriculum: Lisbon (CAISL). Porto doesn’t have a dedicated American curriculum school. This is the clearest city decider.
- French curriculum: Both cities have a Lycée Français. Porto’s LFIP is significantly cheaper than Lisbon’s equivalent.
- German curriculum: Both cities have a Deutsche Schule.
- Portuguese state school: Both cities work. Porto schools in Foz, Matosinhos, and Boavista have good experience with expat children.

Enrolment Checklist: What You Need
Whether enrolling in a state school or an international school, you’ll need these for each child:
- Valid passport
- Birth certificate (with certified translation to Portuguese if not in English or Portuguese — confirm with the school)
- NIF (Portuguese tax number) — needed for state school enrolment and useful for international schools too
- Proof of address in Portugal (rental contract)
- Residency permit or proof of residency application in progress
- Vaccination records from your home country — Portuguese schools issue their own vaccination booklet and will align your records with the Portuguese schedule
- Previous school reports (boletim escolar from your home country) — used for year placement
- For separated/divorced parents: notarised consent from the non-relocating parent
State school enrolment opens in April–May for September entry. Contact your local agrupamento de escolas or Câmara Municipal. International school applications — particularly for popular year groups — should be submitted as early as possible, ideally 12 months ahead.
Our Honest Summary
The families who are happiest with their schooling decisions in Portugal are almost always the ones who made the decision early, researched both the state and international options honestly, and visited schools in person before committing. The families who struggle are usually those who assumed the international school they wanted would have a place, or who put an older child into the state system hoping they’d adapt quickly.
The school decision is not one to make from a spreadsheet. Visit Portugal before you move. Walk into the schools you’re considering. Talk to the other expat parents — they will tell you things that no website will. And make the school decision first, before you sign a lease or book flights.

Secondary School and Beyond: What Happens After Age 12
Ensino Secundário (Ages 15–18, Years 10–12)
After completing the 3rd cycle of basic education (9th year, age 15), Portuguese students enter ensino secundário — the equivalent of sixth form or senior high school. This is a critical stage for expat families to understand because it leads directly to university entrance.
Three main pathways exist at secondary level:
- Cursos Científico-Humanísticos: academic pathway, divided into four areas (Sciences and Technology; Economics and Administration; Languages and Humanities; Visual Arts). The most common route for university-bound students.
- Cursos Profissionais: vocational courses, combining academic content with professional training. Lead to a level 4 professional qualification and can still provide access to university. Good option for students who prefer applied learning.
- Cursos de Ensino Artístico Especializado: specialist arts pathway for music, dance, and visual arts.
For expat families: children who entered the Portuguese state school system at primary level and are now bilingual will navigate secondary school well. Children who arrive at secondary level (age 12+) face a more challenging language transition — the academic content is harder and the PLNM support less comprehensive than at primary level. For late-arriving teenagers, an international school pathway to IB Diploma is often more practical than Portuguese state secondary.
University Entrance: How the Portuguese System Works
University entrance in Portugal is managed through the CNAES (Concurso Nacional de Acesso ao Ensino Superior) — the national university access competition. Places at public universities are allocated by grades from the 12th year (final year exams, called Provas de Exame Nacional) plus coursework.
For expat children who have completed Portuguese secondary education, the process is the same as for Portuguese students. For children who completed an international curriculum (IB Diploma, A-Levels, Baccalauréat), there is a separate access regime — the Concurso Especial para Titulares de Cursos Estrangeiros — which assesses foreign qualifications for equivalence and allocates places through a parallel process.
Key point: the IB Diploma is well-recognised by Portuguese universities. Children who complete the IB at OBS or CLIP in Porto can apply to Portuguese universities through the special access regime, alongside applications to UK, US, and other European universities.
The 2-Year Residency Rule: Domestic Fees for Expat Children (From 2025/26)
This is one of the most significant recent changes to Portuguese higher education for expat families and is not widely known outside Portugal.
From academic year 2025/2026, students who have been legally resident in Portugal for at least two years are no longer classified as international students for university fee purposes. They are admitted through a specific application process and pay domestic tuition fees rather than international rates.
What this means in practice: a family that moved to Portugal in 2024 with a teenager who is now studying for the IB Diploma at OBS or in Portuguese secondary school will have a child who qualifies for domestic university fees by the time they apply to a Portuguese university — provided they have maintained legal residency throughout.
Domestic university fees in Portugal: approximately €697–€1,100/year for public universities (set by the government annually and linked to the minimum wage). Compare this to international student fees at the same universities, which can run €3,500–€8,000/year for non-EU students.
Note: the 2-year residency must be under a standard residency permit. Time spent on a student visa (residence permit for study purposes) does not count towards this requirement.
Portuguese Universities: What Expat Families Should Know
Portugal has several well-regarded public universities. The most relevant for families in Porto and Lisbon:
- University of Porto (UP) — one of Portugal’s top research universities, consistently ranked in the top 300 globally. Strong in engineering, medicine, sciences, and law. Many programmes offered in English at postgraduate level; undergrad is primarily Portuguese.
- Nova University Lisbon — particularly strong business school (Nova SBE), law, and social sciences. Growing international reputation.
- University of Lisbon (ULisboa) — large comprehensive university, strong across most disciplines.
- University of Coimbra — Portugal’s oldest university (1290), strong in law, sciences, and humanities. UNESCO World Heritage campus.
- Católica University Porto / Lisbon — private Catholic university with strong business and law faculties. Fees are higher than public universities but still competitive by European standards.
For children of expat families who’ve grown up in Portugal and become genuinely bilingual, Portuguese universities represent exceptional value — domestic fees of under €1,000/year for a degree from a ranked institution, in a country they know and in a language they speak. This is a compelling long-term argument for the state school immersion route that doesn’t get mentioned often enough.
