Choose by structure and fit, not reputation: UK universities accept both boards. Cambridge offers more subjects (over 70 at IGCSE, 55 at AS & A Level) and a staged AS-to-A Level route. Pearson Edexcel offers modular International A Levels in 21 subjects, with January, June and October series and unit resits. Many schools mix boards, deciding subject by subject.
How do Cambridge and Edexcel compare at a glance?
| Cambridge International | Pearson Edexcel | |
|---|---|---|
| Subjects | IGCSE: “over 70 subjects”; AS & A Level: “55 subjects” | International A Level: “21 subjects”; International GCSE: wide range, linear or modular in many |
| Upper-secondary series | June and November (March for India and Romania) | International GCSE: May/June and November; IAL: January, June and October |
| A Level structure | AS and A Level; AS results can be carried forward “twice within 13 months” | Modular units, banked on a Uniform Mark Scale; any unit can be resat |
| IGCSE grading | A*–G, or 9–1 in administrative zone 3 | 9–1 |
| Tiers | Core and Extended in Mathematics and the sciences | Only Mathematics A (Foundation and Higher) |
| Onscreen exams | First live digital exams June 2026, Early Adopter schools | 14 subjects across International GCSE and IAL by 2026 |
| Predictions to the board | Forecast grades compulsory | Estimated grades no longer required |
| Becoming a centre | Four steps, “around 12 weeks” | Register interest; Pearson contacts the school |
| Fees | Not published; by region | International fees by regional office |

Cambridge vs Edexcel A Level: linear or modular?
This is the biggest structural difference for schools. Cambridge A Levels can be taken in stages. The Handbook describes AS in one series and A Level later, or all papers together. “AS Level results can be carried forward twice within 13 months of the series when the candidate took the AS Level.” Pearson’s International A Levels are fully modular. Units are banked, graded on a fixed Uniform Mark Scale, and any unit “can be resat”. The better of the two most recent attempts counts, or the best attempt in Mathematics.
Modular IAL suits schools that want banked results early, for UCAS predictions and second chances. Cambridge suits schools that prefer end-of-course assessment and fewer exam sessions. Our IAL modular strategy guide sets out the IAL rules in detail.
IGCSE Cambridge vs Edexcel: which is better?
Neither is better in general; they differ in grading, tiering and subject range. Cambridge IGCSE offers over 70 subjects, A*–G grading (or 9–1 in zone 3), and Core and Extended tiers in Mathematics and the sciences. Pearson International GCSE grades 9–1 and tiers only Mathematics A, so its sciences are single-tier. That matters for departments with a wide ability range: Cambridge’s Core tier caps at C, while Pearson’s untiered sciences give every student access to every grade. See IGCSE Core vs Extended and Edexcel Foundation vs Higher.
How do universities treat each board?
As equivalent to UK A Levels. Cambridge says its International AS & A Levels “are accepted for entrance to UK universities in the same way as the UK A Levels” (Cambridge). Pearson describes its IALs as “comparable to GCE AS/A levels, as confirmed by NARIC”. Neither board’s International A Levels carry UCAS Tariff points, because the Tariff covers only UK-regulated qualifications. UCAS notes that “most admissions teams use International A levels and GCE A levels interchangeably” (UCAS factsheet). For local universities, check national equivalence rules, such as Pakistan’s IBCC or Egypt’s coordination rules. See country guides.
What does each board cost a school?
Neither publishes international fees. Cambridge charges a school application fee, annual programme fees and “a fee for each exam entry”, and says “for full details of the fees for your region please contact us” (Cambridge). Pearson tells schools outside the UK to “contact your local regional office” (Pearson). When comparing, count the whole cost: entries, resits (more frequent with modular IAL), late and amendment fees, and staff time for more exam series.
How do you become a centre for each board?
Cambridge describes “four steps to becoming a Cambridge school … which can take around 12 weeks”. They are expressing interest, completing an application, an approval visit and becoming a Cambridge school (Cambridge). Pearson asks schools outside the UK to “complete a short form to register your interest” (Pearson). A school can be a centre for both. Step-by-step guides: becoming a Cambridge school and becoming a Pearson Edexcel centre.
Should a school mix Cambridge and Edexcel?
It can make sense, if done deliberately. Examples include Cambridge IGCSE with Pearson IAL for a modular sixth form, or Pearson International GCSE sciences alongside Cambridge Mathematics. Mixing adds exam-office complexity. There are two sets of series, entry systems, forecast rules and onscreen arrangements. So each mix should answer a specific student need, not habit. Check upcoming changes on both sides before committing, such as Cambridge’s 2027–2029 syllabus revisions and Pearson’s new IAL Computer Science. See the Exam Board Change Radar.
How schools do this with AI Buddy
AI Buddy covers both boards, with past-paper-style questions across 26 IGCSE and A Level subjects for Cambridge and Pearson Edexcel, marked instantly. Schools running a mix, or moving a subject between boards, can keep one practice and analytics platform across both. Departments can also compare how the same cohort performs on each board’s question styles before deciding.
Frequently asked questions
Is Cambridge or Edexcel better for IGCSE?
Neither is better in general. Cambridge offers more subjects and Core/Extended tiers; Pearson grades 9–1, tiers only Mathematics A, and offers linear or modular routes in many subjects. Choose per subject.
What is the difference between Cambridge A Level and Edexcel IAL?
Cambridge A Levels are taken as AS and A Level, with AS results carried forward within 13 months. Pearson IALs are modular, with banked units, a fixed Uniform Mark Scale, three series a year and resits for any unit.
Do UK universities accept Edexcel IAL and Cambridge A Levels equally?
Both boards state their qualifications are accepted like UK A Levels. Neither carries UCAS Tariff points, and UCAS notes most admissions teams treat International and GCE A Levels interchangeably.
Can a school offer both Cambridge and Edexcel?
Yes. Many international schools are centres for both and choose the board subject by subject.
