An independent report from GlobalSchoolGuide Research. No school pays to be included. Figures are drawn from published outcomes research, examination body statistics and the platform's own curriculum coverage, with sources listed in full at the end of this report. Several of the strongest destination studies were commissioned by the awarding bodies themselves, and this report flags that throughout.
Executive summary
Parents choosing an international school almost always ask the same question last and worry about it most. Which curriculum gives my child the best chance at a good university. It is a fair question and a hard one, because the honest answer sits between two unhelpful extremes. The marketing claim that one pathway clearly beats the rest does not survive scrutiny. Nor does the dismissive view that curriculum makes no difference at all. The published evidence shows real and measurable patterns, but those patterns are shaped by who chooses each pathway as much as by the pathway itself.
This report reads the available data on the International Baccalaureate Diploma, A levels, Advanced Placement and the major national curricula delivered abroad. It sets out where students on each route tend to enrol, how they perform once there, and where the numbers are solid against where they are softer. The aim is not to crown a winner. It is to give relocating families a clear, sourced basis for a decision that should turn on fit, future location and how a child learns, not on a single headline.
Seven findings that define 2026
- International Baccalaureate Organisation research on United States graduates found 62 per cent of Diploma recipients enrolled at a more selective four year university, against about 35 per cent of comparison students.
- In the United Kingdom, HESA analysis found IB holders were more likely than A level holders to attend a top 20 provider and to earn a first class degree, at about 23 per cent against 19 per cent, after controlling for prior attainment.
- The same United States study found 74 per cent of Diploma graduates went straight to college, against 64 per cent of all United States school leavers, and were far more likely to still be enrolled a year later.
- Advanced Placement is an admissions strengthener rather than a diploma. College Board reports that about 85 per cent of selective colleges say AP experience favourably affects admission decisions.
- A levels remain the established route into selective United Kingdom universities, prized for depth and specialisation, and convert directly through the UCAS tariff where an IB score of 38 maps to roughly A*AA.
- National curricula travel further than many families assume. The German Abitur and French Baccalaureate are recognised across Europe and most major destinations, though United States recognition varies by institution.
- The single biggest caveat is selection bias. Much of the strongest destination evidence was commissioned by the awarding bodies, and the students who choose each pathway differ before they ever sit an exam.
Key statistics
The four indicators below anchor the report. Each is traceable to a named source set out in the methodology, and each is presented as reported rather than re-modelled. They describe different systems and different countries, so they should be read alongside one another rather than stacked into a single league table.

Methodology in brief
This report synthesises published outcomes research rather than conducting a new survey. It draws on four evidence types. First, awarding body outcomes studies, principally International Baccalaureate Organisation research on United States and United Kingdom destinations. Second, independent statistical analysis, including Higher Education Statistics Agency work referenced in funding council reporting. Third, examination body performance data from the International Baccalaureate Organisation and College Board. Fourth, GlobalSchoolGuide's own coverage of curriculum availability across more than 50 cities.
Every figure is attributed to its source in the text. Where a study was commissioned by the awarding body whose pathway it measures, that is stated, because the funding shapes how confidently a reader should treat the result. No precise destination percentage has been invented. Where data is thin, for example direct outcome comparisons for national curricula delivered abroad, the report says so and offers context rather than a number. Underlying references are linked in full at the end and the working notes are available on request.
Why this question is hard to measure
Before any number, a warning about all of them. The link between a school curriculum and a university outcome looks like a clean cause and effect, and it almost never is. Three problems run through every study in this field, and a parent who understands them will read the rest of this report far more usefully than one who does not.
The first problem is selection. Students do not arrive at the IB, A levels or Advanced Placement at random. The IB Diploma is demanding and tends to attract academically confident, well supported students, often at well resourced schools. If those students later enrol at selective universities at higher rates, part of the reason is who they already were, not only what they studied. Good research tries to control for prior attainment, and the better studies in this report do, but no control is perfect.
The second problem is who paid for the study. The most detailed destination data on the IB comes from the International Baccalaureate Organisation, the body that runs the IB. The most positive framing of Advanced Placement comes from College Board, which owns AP. This does not make the figures false. The underlying datasets, such as United States enrolment records, are real. It does mean a reader should weight an awarding body's account of its own pathway as strong but interested evidence, and look hardest for the independent analysis that survives that test.
The third problem is that destination is not the same as outcome. A place at a selective university is a milestone, not a result. What a student learns, whether they complete the degree, and where they go afterwards matter at least as much. A few studies reach into those later stages, and they are the most valuable, because completion and attainment are harder to explain away by selection alone.
With those caveats in place, the patterns are still worth knowing. They are real, they are reasonably consistent, and they give families a sounder basis for choosing than reputation or word of mouth. The rest of this report takes each pathway in turn.
The International Baccalaureate record
The International Baccalaureate Diploma has the most thoroughly documented university record of any international pathway, partly because the International Baccalaureate Organisation invests heavily in destination research. The headline finding from its United States work is striking. Tracking Diploma students against comparison groups, the research found that 62 per cent of Diploma recipients enrolled at a more selective four year institution, while course students and non recipients sat at about 34 and 35 per cent respectively. On immediate college entry, 74 per cent of Diploma graduates went straight on to higher education against 64 per cent of all United States school leavers.
The pattern continues past the admissions gate. Of Diploma graduates who started college straight after school, 88 per cent returned to the same institution the following year, against 72 per cent of United States students overall. Retention matters because it speaks to preparation rather than selection. A student who arrives and stays is a student the curriculum readied for the work, not only one a university was willing to admit.
The United Kingdom picture reinforces it from a different angle. Analysis using Higher Education Statistics Agency records, referenced in funding council reporting, found that students holding an IB Diploma were more likely than A level holders to enrol at a top 20 provider once prior attainment was controlled for. They were also more likely to leave with a strong degree. The reported first class rate ran at about 23 per cent for IB holders against 19 per cent for A level holders, with a meaningfully higher probability of an upper second as well. IB holders were also more likely to be in further study six months after graduating.
Two things should temper the enthusiasm. The United States and United Kingdom studies were both connected to the International Baccalaureate Organisation, and the selection problem described earlier applies with full force, since Diploma cohorts skew academically strong. Even so, the degree attainment findings are harder to dismiss, because they measure what happened after admission, where a university's selection no longer drives the result. On the current evidence, the IB Diploma's claim to prepare students well for selective study, not just to get them through the door, is the best supported of any pathway here.
Performance data gives the context. In the May 2024 session the global average Diploma score was 30.32 points out of a maximum 45, the pass rate was 80 per cent, and the average subject grade was 4.85 out of 7, on International Baccalaureate Organisation figures. About 193,000 candidates sat Diploma and Career related Programme assessments, and roughly 9 per cent scored 40 points or more, the band that opens the most selective offers. Families weighing the route can read the fuller picture in the platform's guide to IB schools and the dedicated International Baccalaureate overview.

A levels and the United Kingdom route
A levels are the established academic route into United Kingdom universities and a widely respected qualification well beyond Britain. Their character is the mirror image of the IB. Where the Diploma is broad, requiring six subjects, an extended essay, theory of knowledge and a service component, A levels are deep, with most students taking three subjects and specialising hard. For a child who already knows the direction they want, that depth is a genuine advantage, particularly for medicine, engineering and other subjects where universities want demonstrated strength in two or three specific areas.
The UCAS tariff makes the conversion explicit. United Kingdom universities express offers in tariff points or in grades, and the two systems map onto one another, with an IB score of around 38 points treated as broadly equivalent to A*AA at A level. Selective courses commonly ask for A*AA or AAA at A level, or 38 to 42 points at IB with specified higher level grades. The practical effect is that both pathways can reach the same universities, but they get there by different routes, and an offer that looks harder on paper for one system often reflects how that system is graded rather than a higher real bar.
The honest position on outcomes is that the comparative United Kingdom data, as set out above, was produced in the context of IB research and tends to read in the IB's favour on degree attainment. That does not make A levels a weaker preparation for the right student. It reflects that the comparison was framed by one side. A levels continue to send very large numbers of students into the most selective British universities every year, and for a specialist heading for a United Kingdom destination they remain an excellent and well understood choice. The platform sets out the trade offs in detail in its guide to A levels and the blog comparison of A levels against the IB for United Kingdom universities.
Advanced Placement and the United States route
Advanced Placement occupies a different category from the IB and A levels, and confusing it for a diploma is a common parental error. AP is not a school leaving qualification. It is a set of college level courses and examinations layered on top of a United States high school diploma. A student does not graduate with AP. They graduate with a diploma and a transcript that, ideally, shows several AP courses and strong scores. That distinction shapes everything about how AP affects university outcomes.
Within the United States admissions system, AP functions as a signal of rigour. College Board reports that about 85 per cent of selective colleges say a student's AP experience favourably affects admission decisions, because it shows the applicant has stretched beyond the standard curriculum. The performance link runs further. College Board research associates scores of 3 or higher with higher college graduation rates and a greater likelihood of finishing a degree on time, against academically similar students who did not take AP. Participation has grown steadily, with more than 1.2 million students in the United States class of 2024 sitting AP examinations and about 22.6 per cent of that class scoring 3 or higher on at least one exam.
Read carefully, the AP evidence is real but narrower than IB destination data. It speaks mainly to the United States system, it comes from the body that owns the programme, and the graduation findings carry the same selection caveat as everywhere else, since students who load up on AP courses differ from those who do not. The fair conclusion is that AP strengthens a United States application and signals readiness for college work, but it does so as part of a transcript rather than as a standalone passport. For families targeting United States universities, the practical questions are how many AP courses a school offers and how its students score, not whether AP appears on the prospectus. The platform covers the mechanics in its guide to the American curriculum and the comparison of the IB against AP on university outcomes.
National curricula delivered abroad
Beyond the three international heavyweights sit the national curricula exported through school networks, principally the French and German systems but also Indian, Canadian and others. These are sometimes overlooked in outcome discussions because comparative destination studies barely exist for them. That absence is itself worth stating plainly. There is no robust, independent dataset comparing, say, French Baccalaureate leavers from international schools with IB leavers on university destination, so anyone claiming a clean ranking is guessing.
What can be said is about recognition, which is well documented. The German Abitur and the French Baccalaureate are mature, respected university entrance qualifications. Within Europe they sit at a comparable level to the IB within shared qualification frameworks, which makes recognition across European universities consistent and largely frictionless. Both are accepted by universities across the major global study destinations, including Australia and New Zealand, which operate structured frameworks for evaluating them. The main area of variation is the United States, which has no national system for recognising foreign qualifications, so an Abitur or French Baccalaureate student is assessed institution by institution, generally as equivalent to a strong high school diploma.
For relocating families, the practical lesson is about continuity rather than ranking. A French or German curriculum delivered abroad is an excellent choice for a family likely to return home or to move within Europe, because the qualification is portable within those systems and the transition back is smooth. It is a less natural fit for a family aiming squarely at United States or United Kingdom universities from a non European base, where an international pathway may carry fewer recognition questions. The platform sets out the structure of the French curriculum and the wider options in the curriculum hub.
| Curriculum | Main award | Strongest destination evidence | Guide |
|---|---|---|---|
| International Baccalaureate | IB Diploma, 45 points | Detailed US and UK destination and attainment research | IB schools |
| A levels | A level grades, UCAS tariff | Long established UK selective entry record | A levels |
| Advanced Placement | AP exams on a US diploma | US admission signal and graduation rate research | American curriculum |
| French Baccalaureate | French Baccalauréat | Strong European recognition, thin comparative data | French curriculum |
| German Abitur | Abitur | Strong European recognition, thin comparative data | Curriculum hub |
GlobalSchoolGuide synthesis. Destination evidence varies widely in depth and independence between pathways.
The pathways side by side
Stacking the routes against one another is tempting and slightly dishonest, because they answer different questions for different families. Still, a structured comparison helps a parent see the trade offs at a glance, provided it is read as a map rather than a scoreboard. The table below summarises the shape of each pathway, the destinations it serves most naturally, and the strength of the evidence behind its university claims.
| Pathway | Breadth or depth | Natural destinations | Evidence strength |
|---|---|---|---|
| IB Diploma | Broad, six subjects plus core | Globally portable | Strongest, though largely IB commissioned |
| A levels | Deep, three subject specialism | United Kingdom and Commonwealth | Established record, less independent comparison |
| Advanced Placement | Enrichment on a diploma | United States | Solid within the US, College Board sourced |
| French and German national | National structure | Europe and home country | Strong recognition, thin comparative data |
GlobalSchoolGuide synthesis from the sources in the methodology. Evidence strength reflects both depth and independence.
Read across the table and the real conclusion appears. The IB Diploma has the best documented and most portable record, which is why it suits internationally mobile families who cannot yet name a destination country. A levels offer unmatched depth for a child already pointed at a United Kingdom destination or a specialist subject. Advanced Placement is the natural choice for a family settled on the United States system. National curricula win on continuity for families likely to return home or move within Europe. None of this is about one pathway being better. It is about matching the route to where the child is likely to end up and how they prefer to learn.

What it means for parents
The first implication is to treat destination statistics as a weak signal, not a verdict. The numbers in this report are real, but they are heavily shaped by who chooses each pathway and by who funded the studies. A family that picks a curriculum because of a headline figure, against the grain of how their child actually learns, is optimising the wrong variable. The evidence supports the IB as a strong all rounder and a portable one, but it does not support abandoning a child who thrives on depth for a broad programme that will stretch them thin.
The second implication is that the individual school matters more than the curriculum label. A strong school running A levels will serve a child better than a weak school running the IB, and the destination data cannot see that difference because it aggregates across schools. The questions that move the needle are about teaching quality, subject results at that specific school, university guidance, and the breadth of subjects offered, none of which appear in a curriculum level statistic. Comparing real schools, rather than abstract pathways, is where a decision should be made.
The third implication is about location. The single most useful predictor of which pathway fits is where the child is likely to apply to university. A family certain of a United States future should weigh AP and the American system seriously. One aiming at the United Kingdom can choose A levels or the IB with confidence. One that genuinely does not know, which describes many relocating families, gains most from the portability of the IB. This is why pathway availability is worth checking city by city before committing, since the mix of IB, A level and national provision varies sharply between markets such as Dubai, Singapore and London. The platform's Compare tool, fee calculator and city guides exist to turn that judgement into a shortlist, and the wider sector context is set out in the State of International Schools 2026 report.
What it means for schools
For schools and operators, the outcomes question is increasingly one of evidence rather than assertion. Parents have access to more comparative data than ever, and the schools that benefit are those willing to publish their own results honestly, including subject level performance and genuine university destinations rather than a curated list of famous names. A school that can show where its own leavers actually went, year on year, holds a stronger position than one leaning on the reputation of a curriculum it happens to offer.
There is also a responsibility not to overclaim. Marketing that implies a curriculum guarantees a selective university place misreads the evidence and sets families up for disappointment. The defensible message is that a good school, running a curriculum well, prepares a child for the universities that suit them. Schools that frame outcomes that way, and back it with their own data and strong university counselling, will earn the trust that converts enquiries into enrolments. The throughline matches the rest of the platform. Independent, unsponsored comparison is what lets parents believe what a school tells them, which is why this report carries no paid placement.
Forward look to 2027
Three shifts are likely to shape this question over the coming year. The first is better data. Graduate outcome tracking is improving in several systems, and as completion and employment data become easier to link to entry qualifications, the field should move beyond admission rates toward the more meaningful measures of whether students finish and thrive. That evolution favours pathways that prepare students well, not only those that select well.
The second is the steady spread of the IB and of bilingual models into markets that were historically A level or national curriculum strongholds, which will widen choice in many cities and sharpen the comparison families face. The third is growing scrutiny of awarding body research. As independent analysts and journalists pay closer attention to who funds outcome studies, the most credible claims will be those that survive external replication. For families, the practical guidance does not change. Choose for fit and likely destination, compare real schools rather than labels, and treat any single statistic, including the ones in this report, as one input among several.
Frequently asked questions
Do IB students really get into better universities than A level students?
The published evidence points that way, with caveats. International Baccalaureate Organisation research on United States graduates found that 62 per cent of Diploma recipients enrolled at a more selective four year institution, against about 35 per cent of comparison students. In the United Kingdom, HESA analysis found IB holders were more likely than A level holders to attend a top 20 provider and to earn a first class degree. Many of these studies were commissioned by the IB, so they should be read as strong but interested evidence rather than neutral ranking.
Which curriculum is best for getting into a top university?
No single curriculum is universally best. The IB Diploma has the strongest published destination record and travels well across countries. A levels remain the established route into selective United Kingdom universities and allow deep specialisation. Advanced Placement strengthens a United States application and signals readiness for college work. The right pathway depends mainly on where a child is likely to apply and how they learn.
What is the global IB pass rate and average score?
In the May 2024 session the global average Diploma score was 30.32 points out of 45 and the pass rate was 80 per cent, on International Baccalaureate Organisation figures. About 193,000 candidates sat Diploma and Career related Programme assessments, and roughly 9 per cent scored 40 points or more.
Does Advanced Placement help with college admission?
College Board reporting states that the large majority of selective United States colleges say a student's Advanced Placement experience favourably affects admission decisions, and that students scoring 3 or higher tend to have higher college graduation rates. AP is an enrichment layer on a United States high school diploma rather than a standalone diploma, so its value sits alongside the wider transcript.
Are national curricula such as the Abitur and French Baccalaureate recognised abroad?
Yes. The German Abitur and French Baccalaureate are well established university entrance qualifications recognised widely across Europe and accepted by universities in most major study destinations. Recognition outside Europe varies by institution, particularly in the United States, which has no national framework for evaluating foreign qualifications.
How should parents use university outcome data when choosing a school?
Treat destination data as one signal among several. Curriculum shapes the pathway, but the individual school, teaching quality, the child's fit and the family's likely future location matter at least as much. Compare schools on curriculum, fees and stage, read inspection reports, and weigh where the child is most likely to thrive rather than chasing a headline statistic.

Methodology and data sources
This report synthesises published outcomes research, examination body statistics and GlobalSchoolGuide's own curriculum coverage. It does not present a new survey. Destination and attainment figures are reported as published by their sources, rounded where appropriate to avoid implying false precision. Where a study was commissioned by the awarding body whose pathway it measures, that is noted in the text, because independence affects how confidently a figure should be read. Where comparative data does not exist, particularly for national curricula delivered abroad, the report states the gap rather than filling it with an estimate.

A note on independence. GlobalSchoolGuide is an independent guide to international schools. No school pays to be listed or ranked, and this report carries no sponsored placement. Several of the strongest destination studies cited here were funded by the awarding bodies whose pathways they assess, and this report flags that wherever it occurs. Where figures could not be sourced or honestly compared, they have been described as gaps rather than invented.
