A framework for comparison
Three questions usefully frame any comparison of school leaving qualifications. First, breadth versus depth: how many subjects does the qualification require and how deeply does each go? Second, assessment style: is the qualification dominated by external examination, by school-graded coursework, by oral defence, or by some mix? Third, university recognition: which universities accept the qualification directly and which require supplementation? The right qualification for any family is the one whose answers to these three questions fit the pupil and the intended next step.
Difficulty is rarely a useful frame because each qualification calibrates its standards to a different cohort and a different expectation of preparation. A pupil who has been studying in the French system from age six finds the Baccalauréat natural and the IB Diploma demanding; the same pupil flipped into the IB from age sixteen would find the inverse. The honest comparison is structural, not about which is harder.
A Levels (UK, international)
A Levels are a depth-first qualification. Pupils typically take three or four subjects across two years (Year 12 and Year 13), with most subjects assessed by terminal external examination in May or June of Year 13. The qualification awards grades A* to E on a seven-band scale. Universities set offers in grade combinations like A*AA, AAB, or in UCAS tariff points totals.
The qualification's strength is the depth of each subject, which closely mirrors first-year undergraduate work in the same field. The weakness is the narrow range; pupils who drop sciences at sixteen will find some university routes closed at eighteen. Cambridge International, Pearson Edexcel International and AQA International offer A Levels that map directly onto the UK qualification and are accepted by universities worldwide, as our piece on the UCAS tariff for A Levels explains.
The IB Diploma
The IB Diploma is a breadth-first qualification. Pupils take six subjects across the two-year programme, with three at Higher Level and three at Standard Level, plus the three core components (Theory of Knowledge, Extended Essay, Creativity Activity Service). The Diploma awards points up to 45, with strong universities setting offers in the 36 to 40 range and elite courses asking for 38 plus.
The Diploma's strength is the combination of breadth and the core, which builds independent research and critical thinking habits valued by selective universities. The weakness is the workload, which is heavier than three A Levels by most measures, and the lower flexibility for pupils with one weak subject area. The piece on A Level versus IB for UK universities compares the two routes for pupils targeting UK admission.
Compare schools by leaving qualification
The school finder filters schools by leaving qualification, board and curriculum. The compare tool sets two or three schools side by side on results, subjects offered and university destinations. Visit our curriculum hub for cluster guides on each pathway.
French Baccalauréat and Bac International
The French Baccalauréat is taken in Première (the equivalent of Year 12) and Terminale (Year 13), with results expressed on a 20 point scale. The Bac général covers a wider subject range than A Levels, with a strong philosophy requirement and one or two specialist subject pairs chosen at the start of Première. The qualification was restructured in 2021 and continues to evolve, with the 2026 cohort sitting under the post-reform framework.
The Bac International (OIB) is a bilingual variant available at French schools running an international section. Pupils sit additional papers in the partner-country language and literature, taking the qualification beyond the standard French Bac in depth and reach. The OIB enjoys particularly strong recognition with Russell Group, Ivy League and continental European universities. Our piece on the French Baccalauréat covers the structure in detail.
German Abitur
The Abitur is the German leaving qualification, taken at the end of Year 13 with results expressed as a single overall grade on a scale where 1.0 is the strongest and 4.0 is the threshold for passing. Pupils take four or five examination subjects in Year 13 plus a school-assessed component covering the two years of upper secondary. The German federal states (Länder) calibrate their Abitur examinations slightly differently, with broad equivalence across states for university admission.
The qualification's strength is its breadth (eight or more continuing subjects through to school leaving) and its rigorous independent-thinking expectations. German universities admit on Abitur grade directly, with most courses requiring a 2.0 or stronger overall grade. UK and US universities recognise the Abitur on competitive terms; the Abitur to A Level conversion runs broadly that a 1.0 to 1.3 Abitur sits at A*A*A* level, 1.4 to 1.8 at A*AA to AAA, and 1.9 to 2.4 at AAA to AAB.
US high school diploma and AP
The US high school diploma is a graduation-style qualification awarded by the school based on coursework, attendance and credit accumulation across four years. The diploma alone is not a strong academic signal for selective universities, which is why college admission in the US relies heavily on standardised tests (SAT or ACT), grade point average, AP exam performance and the personal essay.
Advanced Placement (AP) examinations sit on top of the high school diploma and provide the academic depth signal that selective universities require. A pupil with seven or eight strong AP scores plus a strong GPA and SAT looks competitive at Ivy League and Russell Group universities. AP scores are also accepted for first-year university credit at many US institutions. UK universities accept the US high school diploma if accompanied by at least three AP scores of 4 or 5 in subjects relevant to the intended degree.
Australian ATAR
The Australian Tertiary Admission Rank (ATAR) is a percentile-rank summary of a pupil's performance across the Year 12 examinations of an Australian state. The pupil's underlying subjects and scaled scores vary by state (HSC in New South Wales, VCE in Victoria, WACE in Western Australia, and equivalents elsewhere), but the ATAR is calibrated on a national scale from 0 to 99.95. Australian universities admit primarily on ATAR, with course-specific thresholds.
The ATAR is well recognised by universities across Australia, New Zealand, the UK, Canada, the US, Singapore and Hong Kong, with each country publishing its own conversion table. UK universities typically convert a strong ATAR (95 plus) into an A*AA equivalent for admission purposes. The qualification's strength is its compatibility with onward Australian study; its limitation is that the conversion tables for non-Australian universities are less granular than the ATAR scale itself.
Side by side
| Qualification | Subjects | Assessment | Global recognition |
|---|---|---|---|
| A Level | 3 to 4 | Mainly terminal exam | Very high |
| IB Diploma | 6 plus core | Mixed exam and coursework | Very high |
| French Bac / OIB | 6 to 8 | Mixed exam, oral, coursework | High |
| German Abitur | 8 plus | Mixed exam and school grade | High |
| US Diploma plus AP | 6 to 8 plus AP exams | Coursework plus AP exam | High with AP, low without |
| Australian ATAR | 5 to 6 | State exam plus assessment | High in Anglosphere |
No single qualification dominates. The right choice depends on where the pupil expects to apply to university, the academic profile that suits the pupil's strengths and the school's available offering. Use the compare tool to see which schools in your target city offer which qualifications, and the school finder to filter by leaving qualification.

Frequently asked questions
Which school leaving qualification is best for global university entry?
The IB Diploma has the broadest global recognition, accepted on equal or near-equal terms by universities in every major destination country. A Levels and the French Baccalauréat also enjoy wide international recognition. The US high school diploma alone is not usually sufficient for non-US universities without supplementary qualifications such as AP exams or SAT scores.
How do A Levels and IB compare in difficulty?
A Levels are deeper in three subjects; the IB Diploma is broader across six. Most universities consider strong outcomes on either qualification equivalent. The total workload of an IB Diploma exceeds that of three A Levels, particularly because of the Extended Essay and Theory of Knowledge components.
Do all qualifications convert into UCAS tariff points?
No. A Levels, IB, BTECs, Cambridge Pre-U, Scottish Advanced Highers and several European qualifications have UCAS tariff values. The French Baccalauréat, German Abitur, US high school diploma and Chinese Gaokao sit outside the tariff and are assessed directly against each UK university's published international entry requirements.
