The UK has its own system — and a genuine international layer too
It is worth stating plainly: the UK's mainstream school system is built around GCSEs at around age 16 and A-levels at 18 (with different qualification names in Scotland), and most schools, state and independent, teach towards these. This guide is not about avoiding that system, but about the meaningful number of schools in the UK, mostly independent, that additionally or instead offer an international curriculum, most commonly the International Baccalaureate Diploma Programme, and in a smaller number of cases the full IB continuum from primary through to diploma level.
A further, smaller group of schools in the UK serve specific expatriate communities directly, teaching in another language or towards another country's own curriculum framework, which can be a relevant option for families planning a limited stay in the UK who want continuity with their home country's system.
For a relocating family, the practical question is rarely "which system is best" in the abstract, but which combination of curriculum, location and school culture matches what your child already knows, what your family expects to do next, and what specific universities or systems your child may re-enter later. Treat curriculum as one factor among several in choosing a school, not the only one, and be wary of any source that presents one qualification as straightforwardly superior to another.
What the IB Diploma actually changes
Questions to ask a school about its international offer
- Which specific IB programmes does the school currently run (PYP, MYP, DP), and at which ages?
- Is the IB Diploma the only sixth-form option, or does the school also offer A-levels?
- If the school teaches another country's national curriculum, is it fully in that language, bilingual, or English-medium?
- How does the school support a transition into or out of the IB for pupils moving from a different system?
Where a UK school offers the IB Diploma Programme as a sixth-form option, it typically sits alongside, or occasionally instead of, A-levels. The two qualifications differ in structure: A-levels generally involve deep specialisation in usually three or four subjects, while the IB Diploma requires a broader spread of six subject areas alongside its core components (typically Theory of Knowledge, an extended essay, and creativity/activity/service requirements).
Which is the better fit depends entirely on your child's academic style and future plans, not on one qualification being objectively superior, and universities in the UK and internationally generally accept both, though you should verify specific course entry requirements with target universities directly if this matters to your planning. Ask each school which pathway it currently offers, since not all schools offer both, and some only offer the IB Diploma at Year 12/13 while others run the full continuum from much earlier.
The IB continuum below sixth form: PYP and MYP
Where a school runs the full IB continuum rather than only the Diploma Programme, younger pupils may follow the Primary Years Programme (PYP) and then the Middle Years Programme (MYP) before reaching the Diploma at sixth form. These earlier programmes are structured quite differently from a typical UK primary or early-secondary curriculum, with an emphasis on inquiry-based, cross-disciplinary units of work rather than a fixed subject timetable in the same way GCSEs build toward. Families whose children are used to a more traditional, subject-by-subject curriculum sometimes find this transition takes a term or two to adjust to, more in style than in academic difficulty.
Not every school running an IB continuum offers all three levels; some run PYP and DP without MYP, for instance, or introduce the IB only at Diploma level while using a different framework beforehand. Ask specifically which stages a school runs, since "an IB school" can mean quite different things depending on which parts of the continuum it actually teaches.
Bilingual and dual-language schools
The UK has a number of schools built around bilingual education or another country's national curriculum, often serving a specific expatriate community historically settled in the UK. These schools can suit families planning a limited posting who want their child to keep pace with a home-country curriculum, or families who simply want to maintain a second language at native or near-native level through schooling rather than only at home.
Entry requirements for these schools sometimes include an existing level of proficiency in the relevant language, particularly at older ages, so ask directly and early whether your child would need language support to join, and what that support looks like if offered.
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.
American curriculum and AP options
A number of schools in the UK, generally originally set up to serve American and international families, teach an American-style curriculum through to high-school graduation, often incorporating Advanced Placement (AP) courses in the final years alongside or instead of A-levels or the IB. This can be a genuinely useful option for a family who expects to return to, or move on to, the US college system, since it keeps a child's transcript and grading structure aligned with that system throughout their time in the UK.
As with the IB, confirm directly with any specific school which combination of American curriculum, AP and other qualifications it currently offers at your child's stage, since offerings can differ meaningfully even between schools that both describe themselves as "American curriculum."
Choosing between a British and an international pathway
If your family expects to stay in the UK long-term or return to the UK repeatedly, a British-curriculum school leading to GCSEs and A-levels keeps your child aligned with the system most UK universities and employers are most familiar with, and avoids any transition risk later. If your family is more likely to move again, especially to another country with an IB-friendly university system, or if you specifically value the IB's broader subject spread, an IB-track school may fit better.
For families with school-age children already partway through another country's curriculum, continuity often matters more than which system is theoretically "better": moving a child mid-way through a GCSE or IB-equivalent course elsewhere into a different system in the UK is a genuinely significant transition, and is worth discussing directly and specifically with the receiving school's academic staff, not just its admissions office, well before you commit to a start date.
How curriculum choice interacts with university applications
Whichever pathway your child follows, UK and many international universities generally accept a range of final qualifications, including A-levels, the IB Diploma, and other recognised national qualifications, though individual course entry requirements vary and should be checked directly with target universities, especially for competitive courses with specific subject requirements. Do not assume any qualification is universally preferred; ask the universities your child may realistically apply to what they specifically require or recommend for the course in question, ideally a couple of years before applications are due.
London, Oxford and Cambridge: where international curriculum options concentrate
London has by far the largest concentration of IB, American-curriculum and other international-pathway schools in the UK, reflecting its size and international population, and offers the widest genuine choice if curriculum is your top priority. Oxford and Cambridge each have a smaller, well-established set of international-curriculum options, generally fewer in number but each with its own long track record; families based in or near these two cities usually have a narrower but still workable shortlist, and should factor in commute distance if a preferred school is not within the town itself.
Outside these three areas, international curriculum options exist but are more sparsely distributed, so if you are relocating to a smaller city or a more rural area, it is worth checking early in your planning how far you would realistically need to travel for a specific curriculum, since this can be a genuine constraint on an otherwise appealing school choice.
What to ask a school before assuming its curriculum offer fits your child
Because curriculum offerings change over time and differ meaningfully even between similarly branded schools, build a short, specific set of questions for any shortlisted school: which qualifications are currently taught in the exact year group your child would join; whether the school has experience receiving pupils partway through an equivalent course elsewhere, and what that transition typically looks like; and how the school supports pupils whose first language is not English if the teaching is not in your child's strongest language. Ask, too, about the size of the cohort taking a particular pathway — a school offering the IB Diploma to a handful of pupils each year has a different dynamic from one with a large, well-resourced IB programme, and neither is automatically better, but it is a real difference worth knowing about.
Frequently Asked Questions
Do all UK schools offer the IB, or is it only at certain schools?
Only a subset of UK schools, mostly independent, offer the IB, and even among those, some offer only the Diploma Programme at sixth-form level while others run the full continuum from primary age. Always confirm what a specific school currently offers.
Is the IB Diploma harder to get into university with than A-levels?
Neither is inherently harder; UK and many international universities accept both, though specific course entry requirements vary. Check directly with target universities about what they require or prefer for the course your child may apply to.
Can my child switch from A-levels to the IB, or vice versa, partway through?
This is generally difficult once a student is partway through either course, since the structures and assessment timelines differ significantly. It's much more common and manageable to choose a pathway before starting the two-year sixth-form course.
Are there schools in the UK that teach a curriculum from another country?
Yes, a number of schools teach bilingually or towards another country's national curriculum, often serving specific expatriate communities. Availability and language requirements vary by school — ask directly if this fits your family's situation.
What does 'American curriculum' mean at a UK school?
It generally refers to a school following a US-style curriculum structure, sometimes incorporating Advanced Placement (AP) courses, aimed at keeping students aligned with the US education system. The exact combination of courses offered varies by school — confirm directly.
Do international curriculum schools in the UK only exist in London?
No, though London has the largest concentration given its international population. Oxford and Cambridge, among other areas, also have schools offering the IB or bilingual programmes — check what's available in your specific area.
Will my child need to already speak another language to join a bilingual school?
It depends on the school and the age of entry; some require existing proficiency, particularly for older pupils, while others admit beginners at younger ages. Ask the specific school directly about its language entry requirements.
Does choosing an IB school limit university choices later?
Generally no, since the IB Diploma is widely recognised, but always verify specific subject or grade requirements with target universities and courses, since requirements do vary and can be more specific for certain competitive courses.
