Why are there so many GCSE and A-level exam boards?

Parents new to the English school system often discover that two students can both take “GCSE Chemistry” or “A-level Chemistry” yet sit different papers from different organisations. Families hear AQA, Edexcel, OCR, WJEC or Eduqas and wonder which is “the real” board — or which is easier. This guide explains what exam boards do in England, how they relate to government content rules, and what to check before you download past papers or buy a revision book.

Same qualification name, different exam papers

In England, Ofqual regulates qualifications.[1] Ofqual’s background note for provisional summer 2026 entries states that four exam boards offer GCSE, AS and A-level qualifications in England:[2]

• AQA Education (AQA)
• Cambridge OCR
• Pearson Education Ltd. (Pearson)
• WJEC-CBAC Ltd. (WJEC Eduqas)

Ofqual’s 2025 delivery report likewise refers to AQA, Cambridge OCR (which changed its name from OCR in September 2025), Pearson and WJEC (Eduqas) as the boards offering GCSE, AS and A-level specifications in England.[3]

Shared rules, separate products. For Chemistry, the Department for Education publishes subject content that every awarding organisation must follow, and Ofqual sets subject-level conditions.[4][5][6][7] Those requirements set a shared floor. Each board then writes its own specification, papers and mark schemes. “GCSE Chemistry” or “A-level Chemistry” names a type of regulated qualification, not one national paper. Specifications may add depth, breadth or context within the rules.[4] Treat your child’s own board documents as the authority, and do not assume another board’s materials transfer unchanged.

The main boards in England

• AQA. Ofqual lists AQA Education (AQA).[2] AQA Chemistry specifications use the same legal style.[8][9] Its heritage page notes a 2000 merger created the Assessment and Qualifications Alliance, now simply known as AQA.[10] This article follows AQA Education.
• Pearson and Edexcel. Pearson is one of Ofqual’s four England boards.[2] It publishes Edexcel GCSEs and A levels,[11][12] so “Edexcel” is the brand families usually see, not a fifth board.
• Cambridge OCR. Until September 2025 known as OCR (Oxford, Cambridge and RSA Examinations); now Cambridge OCR, part of Cambridge University Press & Assessment.[13][14] Ofqual records the same change.[3] Those university names do not mean either university sets every school paper.
• WJEC Eduqas. Ofqual lists WJEC-CBAC Ltd. (WJEC Eduqas).[2] Eduqas serves England; WJEC presents itself as Wales’ largest awarding body with Qualifications Wales.[15][16] Same organisation, different regulators, so specifications can differ.[17] Do not treat them as interchangeable.

Ask the school which board and specification each subject uses. Do not assume subjects share one board.

Is one board easier?

It is natural to look for a number to compare, but be careful with grade boundaries — the mark needed for a particular grade on one paper in one exam series. GOV.UK’s grading guidance for England explains that boundaries move with paper difficulty: if a paper is easier than in previous years, boundaries for that paper are higher; if harder, lower — so that it is no easier or harder to get a grade in any given year.[25]

The same guidance says boundaries typically differ between exam boards because grading reflects each paper’s difficulty. A higher boundary with one board than another does not mean that grade is harder to achieve; it reflects that that paper was easier. A lower boundary reflects a harder paper, not that the grade is easier to get.[25]

Ofqual’s 2019 blog on comparing standards between exam boards calls the search for the “easiest” board misguided. Predictions are used to align grade standards across boards so that it is no easier or harder to achieve a particular grade with one board than with another. Board outcomes may still differ with each entry’s prior-attainment profile; that is not the same as one board’s standard being easier.[26]

Distinguish paper demand (which boundaries adjust for) from grade standards (which Ofqual aims to keep comparable across these England GCSE/AS/A-level boards). That is not a claim that papers are identical.

Hypothetical only (not real boundaries): two papers out of 100, with boundaries 70 and 75 for the same grade, do not by themselves prove one paper is “easier to get the grade on”, because the questions differ.[25]

A more useful question than “Which board is easiest?” is “Which board is my child entered for, and do our materials match it?”

Do not mix these up with lookalike international names

Families sometimes confuse England’s GCSE and A-level boards with international products that share Oxford or Cambridge branding:

• OxfordAQA describes itself as a partnership between Oxford University Press (a department of the University of Oxford) and AQA, aimed at international schools.[18] It is not the same product line as domestic AQA GCSE and A-level entries in English schools.
• Cambridge International Education offers programmes such as Cambridge IGCSE and Cambridge International AS & A Levels.[19][20] These are distinct from the GCSE, AS and A-level qualifications that Cambridge OCR offers in England.

If a resource says “Cambridge” or “Oxford”, check whether it means Cambridge OCR (England), Cambridge International, OxfordAQA or something else entirely.

Other UK nations in one paragraph

Ofqual’s entry figures above are for England only.[2] Qualifications Wales regulates qualifications in Wales.[21] In Northern Ireland, CCEA includes CCEA Regulation, which accredits and regulates qualifications offered there.[22][23] Scotland uses National Qualifications (including Highers) through its own national awarding body, not England’s GCSE/A-level boards.[24] Tie questions to the country and regulator that apply.

What to check before using or buying resources

These are practical suggestions, not legal advice.

1. Ask the school for the exam board, the qualification title (for example GCSE Chemistry or Combined Science; AS or A-level) and the specification code, for each subject.
2. Download that board’s current specification PDF from the board’s own website.
3. Prefer the board’s own past papers and mark schemes where they are free to download. If you buy a textbook or revision guide, match it to that board and specification version only.
4. If the school changes board between GCSE and A-level, or between subjects, update your materials list. Last year’s papers may no longer match.

As an example, AQA GCSE Chemistry is 8462, and AQA A-level Chemistry is 7405, with AS Chemistry as 7404 where it is used.[8][9] These codes only illustrate the idea. Your school may use Pearson Edexcel, Cambridge OCR, Eduqas or another permitted entry instead, so get the exact code from the school.

Where to go next

Confirm your child’s exam board and specification, then match Chemistry resources to them rather than comparing boards by difficulty.
