For families committed to the British system, the IGCSE-then-A-Level pathway offers a clear, globally recognised route through secondary school and into university. Several Lisbon schools provide it. This guide explains how the British exam route works in Portugal, which schools offer it and how the qualifications support university entry — useful for any internationally mobile family considering the British pathway.
IGCSE vs GCSE
A frequent point of confusion: British international schools, in Lisbon and elsewhere, almost always offer the IGCSE (International GCSE) rather than the UK domestic GCSE. The IGCSE was designed for international schools, is offered by Cambridge and Pearson Edexcel, and is treated as equivalent to the GCSE by universities and employers worldwide. For practical purposes, a child taking IGCSEs in Lisbon is on the same footing as a GCSE student in Britain.
IGCSEs are typically taken across Years 10 and 11 (around ages 14–16), with students sitting a spread of subjects including English, mathematics, sciences, languages and humanities.
The A-Level stage
A-Levels follow at sixth form, usually over two years (around ages 16–18). Students typically specialise in three or four subjects, allowing depth and early focus — a key difference from the broader IB Diploma. A-Levels remain the classic route into UK universities and are accepted across the world.
Which Lisbon schools offer the British exam route?
| School | Area | Provision |
|---|---|---|
| St. Julian's School | Carcavelos | IGCSE and A-Level (alongside IB and a Portuguese section) |
| The British School of Lisbon | Central / Restelo | Cambridge IGCSE and A-Level |
| Astoria International School | Alvalade | British curriculum to age 18 |
| The Lisboan International School | Central Lisbon | Cambridge / IGCSE pathway (opened 2025; IB Diploma planned later) |
| Greene's College Estoril | Estoril | Specialist IGCSE and A-Level tutorial preparation |
Provision differs by school and changes as newer schools build out their senior years, so confirm the exact sixth-form offer — some schools pair A-Levels with, or offer instead, the IB Diploma. Our British schools in Lisbon guide profiles these schools, and IB schools in Lisbon covers the alternative.
Choosing subjects at IGCSE
The IGCSE years are where a student's spread is at its widest, and the choices made here quietly shape what is possible later.
The general principle is to keep the core broad. English, mathematics and the sciences underpin the widest range of A-level and Diploma options, and languages and humanities are considerably easier to continue than to restart. A student who narrows too early at fourteen can find at sixteen that a subject they now want has a prerequisite they no longer hold.
Two questions are worth putting to the school. Which subjects actually run in a given year — a subject listed in a prospectus may not be timetabled if too few students choose it — and whether any subject the child particularly wants is offered at the level they will need for sixth form.
The A-level decision
At sixth form, a student typically narrows to three or four subjects. This is the great strength of the British route and the point at which it demands the most foresight.
Combinations open and close doors. Some degree courses expect specific subjects; others expect a combination. The sensible sequence is to look at the entry requirements for the sort of course a student might want before the choices are made, not after. Where a direction is genuinely undecided, a combination that keeps several fields open is worth more than one that optimises for a single guess.
Depth is the trade-off for breadth. A student who specialises early gets more time in the subjects they care about and less in the ones they do not — which is exactly what suits some students and exactly what narrows others prematurely.
Four is not automatically better than three. Universities generally make offers on three, and a student stretched across four may perform less well in each. This is a conversation to have with the school rather than a rule.
Exam boards, and why they matter when you move
IGCSEs and A-levels are set by examination boards, and different schools use different ones. Within a single school this is invisible; between schools it is not.
A student moving mid-course can find that the new school follows a different board, with a different specification, different set texts and different assessment structure. The content overlaps substantially, but "substantially" is doing real work in that sentence, and the gaps are the student's to close.
Before any move that lands mid-course, ask both schools which board and specification they follow for each of the child's subjects, and what the new school does to bridge a student across. Schools handle this regularly and can usually give a clear answer.
A-levels or the IB at sixth form?
Where a school offers both — as some Lisbon schools do — the choice can be deferred to sixteen, which is a genuine advantage.
A-levels suit a student with a clear direction who will benefit from concentrating on it. The IB Diploma suits a student who is broadly capable and either does not yet know their direction or actively wants to keep several open. Both are recognised worldwide, and universities make offers on either.
The considerations that tend to decide it in practice are less about prestige than about temperament: how the student copes with sustained coursework versus terminal examinations, whether they want to keep a language and a science running alongside their main interests, and how much they would resent — or welcome — the Diploma's compulsory core. Our IB schools in Lisbon guide sets out what the Diploma involves in practice.
Schools and tutorial colleges
Lisbon's British-route provision includes both full schools and specialist tutorial preparation, and they answer different needs.
A school provides the whole environment — pastoral care, activities, a peer group, progression from earlier years. It is the default for a family with a child of school age.
A tutorial college concentrates on examination preparation, typically in small groups and with a great deal of individual attention. It can suit a student who needs to cover a specific set of subjects intensively, one whose circumstances do not fit a conventional school year, or one preparing for retakes. It provides less of the wider school experience, which for most children is a significant part of what school is for.
If retakes or an unusual timetable are a possibility, ask each institution directly what it can accommodate; policies differ.
Portuguese alongside the British curriculum
A child following the British route in Lisbon will still encounter Portuguese, both as a school subject and, far more insistently, outside the school gates.
How much they leave with varies considerably between schools, and it is worth asking about explicitly rather than assuming. If there is any prospect of the family staying long term, or of the child later moving into the Portuguese system, the level and seriousness of Portuguese teaching becomes one of the more consequential differences between otherwise similar schools.
For a family expecting to move on again, functional Portuguese for daily life is a reasonable objective — and one that is achieved far more reliably through clubs, sport and friendships outside the international community than through timetabled lessons alone.
Timing a move around exam years
| Stage | How disruptive a move is | Practical note |
|---|---|---|
| Primary | Low | Systems diverge least; the easiest window |
| Lower secondary | Low to moderate | A natural entry point before courses begin |
| Mid IGCSE course | High | Board and specification differences bite hardest |
| Between IGCSE and sixth form | Low | The cleanest secondary-stage moment to move |
| Mid A-level or mid Diploma | Very high | To be avoided wherever there is a choice |
If the results do not go to plan
Retakes are mentioned above almost in passing, and they are worth thinking about before they are needed, because a family abroad has fewer options and less time than a family in Britain.
The first question is whether a school will keep a student on to resit. Some will, some will not, and some will only in particular subjects — and the answer determines whether a retake year happens inside a school with its structure and pastoral support or outside one. This is a question to ask at the point of enrolment rather than at the point of crisis, when your negotiating position is weakest and the timetable has already been set.
The second is where the examinations would actually be sat. A student no longer on a school roll becomes a private candidate and needs a centre willing to enter them, which is precisely the gap the tutorial colleges described above exist to fill. Lisbon is better served here than many cities, but availability changes year to year and should be confirmed rather than assumed.
The third is the university consequence, and it is the one families underestimate. A retake changes the year in which an application is made, which affects when offers arrive, what a deferred place is worth, and how the intervening months are spent. It is not a disaster and universities deal with it routinely, but it is a year of a young person's life and it goes better when it has a shape.
None of this is a reason to plan for failure. It is a reason to ask two short questions of any school before enrolment — what happens if a student needs to resit, and where — and then to file the answers.
How the route supports university entry
A-Level grades feed directly into university applications. For UK universities, students apply through UCAS using predicted and then final A-Level grades. For universities elsewhere — including in the United States, Europe and beyond — A-Levels are a well-understood qualification, though some destinations have additional requirements (such as standardised tests for some US universities). Our university admissions guide explains the application routes in detail.
A student taking the British route in Lisbon should keep an eye on the bigger picture: subject choices at A-Level can open or close university courses, so good university guidance from the school matters.

Frequently asked questions
3 questions
Do schools in Lisbon offer GCSEs or IGCSEs?
British international schools outside the UK, including those in Lisbon, almost always offer the IGCSE (International GCSE) rather than the UK domestic GCSE. IGCSEs are offered by Cambridge and Pearson Edexcel, are designed for international schools, and are accepted by universities and employers in the same way as GCSEs.
Link to this questionWhich Lisbon schools offer A-Levels?
Several British-curriculum schools offer A-Levels at sixth form, including St. Julian's and The British School of Lisbon, while tutorial colleges such as Greene's College Estoril specialise in IGCSE and A-Level preparation. Some schools pair or replace A-Levels with the IB Diploma, so confirm the exact sixth-form offer with each school.
Link to this questionAre A-Levels taken in Lisbon accepted by universities?
Yes. A-Levels are an internationally recognised qualification accepted by UK universities through UCAS and by universities across the world. Grades are assessed on the same scale as in the UK, so a student in Lisbon applies on the same footing as one in Britain.
