What the IB actually is: four separate programmes
The International Baccalaureate is not one single curriculum but a family of four distinct programmes, and it is a common misunderstanding to assume a school offering "the IB" teaches all of them. The Primary Years Programme (PYP) covers roughly ages 3 to 12, the Middle Years Programme (MYP) covers roughly ages 11 to 16, the Diploma Programme (DP) is a two-year pre-university course typically for ages 16 to 19, and the Career-related Programme (CP) is a less common alternative to the Diploma aimed at students combining academic study with career-related learning.
A school can be authorised for one, several, or all four of these programmes, and authorisation for one does not imply authorisation for another. When a school in Portugal describes itself as an "IB school," always ask specifically which of the four programmes it is currently authorised to teach, and at which year groups, rather than assuming full continuum provision.
It is also worth understanding the difference between a school that is authorised to teach a programme and one that describes itself as a candidate school working towards authorisation. Candidate status means the school is following IB processes but has not yet been granted full authorisation, which can matter if continuity of the qualification itself is important to your family. Ask a candidate school directly what its authorisation timeline looks like and what happens if authorisation is delayed.
Where IB provision is found in Portugal
IB programmes appear at a number of international schools across Portugal, with a noticeable concentration in greater Lisbon and in Porto, and a presence at some schools elsewhere in the country as well. Some schools combine IB provision with another curriculum, offering, for example, a British curriculum through the early secondary years with the IB Diploma as a post-16 option, or an American curriculum alongside an IB pathway. Others run IB programmes across a fuller continuum from the primary years upward.
Availability and the specific programmes offered change over time as schools apply for and are granted authorisation for new programmes, so treat any list of IB schools, including the school links in this guide, as a starting point for further research rather than a final or complete answer, and confirm current authorisation directly with each school or with the International Baccalaureate Organization itself.
The IB Diploma Programme: what families most often ask about
The Diploma Programme tends to attract the most attention from parents because it is the stage most directly linked to university applications. Structurally, DP students generally study six subjects across defined subject groups, alongside three additional core components: Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service (CAS). This overall structure is set by the IB organisation, but the specific subjects a school can offer within it depends on that school's own staffing, resources and current authorisation, and varies significantly from school to school.
Before assuming a school can support a particular subject combination your child wants to pursue, ask the school directly for its current DP subject list and any constraints on combining subjects across groups. Do not assume a school offering the DP can offer every subject an IB Diploma theoretically allows.
IB vs British A-levels: a genuine choice at several Portuguese schools
A number of schools in Portugal that primarily follow a British curriculum through to age 16 also offer the IB Diploma as an alternative to A-levels in the final two years, giving families and students a real choice at that stage. The two pathways differ meaningfully: A-levels typically allow deeper specialisation in three or four subjects, while the IB Diploma requires breadth across six subjects plus the additional core components.
Neither is inherently more rigorous or better regarded by universities in general, and the right choice depends on your child's academic strengths, learning style and preferred pathway after school. Where a school offers both, ask how it supports students and families in choosing between them, and ask about typical progression from that specific school to universities in the destinations your family is considering.
The Primary Years and Middle Years Programmes
Where a school offers the PYP or MYP, these programmes are generally built around an inquiry-based approach to learning organised through broad units and themes, rather than the more subject-siloed structure typical of many national curricula at the same age. Families whose children join partway through either programme sometimes find the language of "units of inquiry" and skill-based reporting unfamiliar at first compared with a traditional subject-based report card.
If your child would be joining a PYP or MYP school mid-programme rather than at its natural starting point, it is worth asking the school specifically how it supports students transitioning in from a different curriculum, since the inquiry-based structure can take some adjustment even for academically strong students.
Not sure which schools fit your family?
Choosing an international school depends on your child's age, curriculum preference, location and budget. Tell us what you're looking for and we'll help you identify schools worth considering.
Verifying IB authorisation before you decide
Because IB authorisation is programme-specific and can change, this guide will not state which programmes any named school currently teaches beyond what schools themselves describe in general terms. The International Baccalaureate Organization maintains its own official list of currently authorised schools and programmes worldwide, and checking a school's status there, alongside asking the school directly, is the most reliable way to confirm current authorisation before you commit to a decision based on it.
Comparing IB schools against other pathways
Choosing an IB school is not automatically the right decision for every family, and it is worth weighing honestly against British curriculum, American curriculum or Portuguese state and bilingual options depending on your child's needs, your family's plans for future moves, and where your child might eventually apply to university. Our guides to British schools in Portugal and to international schools in Portugal more broadly can help with that wider comparison.
What to ask about teaching quality and resourcing, not just authorisation
Authorisation confirms that a school meets the IB's structural and procedural requirements, but it does not tell you much about how well a specific school delivers the programme day to day. Ask about the experience level of subject teachers in the Diploma Programme specifically, since staff turnover can affect continuity in a two-year course. Ask how university guidance and Extended Essay supervision are resourced, since these are areas where a well-established IB school and a newly authorised one can differ noticeably in practice. Also ask about typical class sizes for less common Diploma subjects, since a school authorised to offer a subject on paper may only be able to run it if enough students choose it in a given year.
IB provision by region: what tends to differ
Greater Lisbon has the widest spread of IB provision, including several schools offering the Diploma Programme alongside another curriculum such as American or British, and a handful running fuller continuum provision from the primary years. Porto's IB schools are fewer in number but include options blending IB with the Portuguese national curriculum, which can suit families wanting an internationally recognised qualification alongside stronger Portuguese integration. Cascais has at least one well-known option combining British curriculum with the IB Diploma at the senior end. Provision in the Algarve and Braga is more limited and tends to appear as one strand within a broader curriculum offer rather than a dedicated IB school, so families drawn to those regions specifically for the IB should confirm current authorisation carefully rather than assuming provision matches what is available in Lisbon or Porto.
How families typically decide between programmes and pathways
For families with a genuine choice between the IB and another pathway, it helps to work through a few concrete questions rather than relying on general reputation. Ask what your child's academic strengths and preferences actually are: a student who thrives with breadth across several subjects and enjoys the reflective, cross-disciplinary elements of Theory of Knowledge and the Extended Essay often finds the Diploma Programme a natural fit, while a student who wants to specialise deeply in two or three subjects early may prefer A-levels. Ask the school what its own students and families say about the choice, and, where possible, speak to current Diploma students or their parents directly.
Also consider your family's likely future moves. If a return to a specific country's university system is likely, ask how universities there typically treat IB Diploma applicants compared with the alternative your child might otherwise take, since recognition and any subject-specific requirements can differ and are worth understanding well before the choice has to be made.
Frequently Asked Questions
Does every IB school in Portugal offer the full IB continuum?
No. A school may be authorised for one, several or all four IB programmes, and this varies significantly by school. Always ask which specific programmes and year groups a school currently offers rather than assuming full continuum provision.
Is the IB Diploma harder than A-levels?
They are structured differently rather than simply harder or easier: the Diploma requires breadth across six subjects plus additional core components, while A-levels allow deeper specialisation in fewer subjects. The right fit depends on your child's strengths and preferences.
Which cities in Portugal have IB schools?
IB provision appears at a number of schools mainly in greater Lisbon and Porto, with some presence elsewhere, though availability changes over time. Confirm current provision directly with schools or via the International Baccalaureate Organization's own records.
Can my child join an IB Diploma school from a different curriculum?
Many students transition into the Diploma Programme from other systems, but the ease of transition depends on the individual child and the receiving school's support for transitions. Discuss your child's specific background with the school directly.
How do I check if a school's IB authorisation is genuine and current?
The International Baccalaureate Organization maintains an official record of authorised schools and programmes. Check there directly and also ask the school for written confirmation of its current status, rather than relying solely on marketing materials.
Do IB schools in Portugal cost more than British curriculum schools?
Costs vary by individual school rather than by curriculum type in any consistent way, and this guide does not quote figures. See our guide to school fees in Portugal for how to compare costs properly.
Can a school offer both British curriculum and IB at the same time?
Yes, this combination exists at a number of schools in Portugal, often with a British-style curriculum through the early secondary years and the IB Diploma as a post-16 option. Confirm the exact structure and choice process with the specific school.
Is the IB recognised by universities outside Portugal?
The IB Diploma is widely recognised internationally, but recognition, credit and entry requirements vary by university and by country, and can change. Check directly with universities your child is considering.
What is the difference between the MYP and a typical secondary curriculum?
The Middle Years Programme is generally organised around an inquiry-based, interdisciplinary approach rather than a more traditional subject-by-subject structure. Ask a specific MYP school how this looks in practice and how it supports students joining partway through.
