England has two different documents controlling what your child is taught, and confusing them is one of the most common sources of parent confusion in the whole system. The National Curriculum is a statutory framework that mainly governs Key Stage 3 (up to age 14) in maintained schools. GCSE and A-level content is set separately — the Department for Education defines broad 'subject content' for each subject, and each awarding body (AQA, Pearson Edexcel, OCR, WJEC/Eduqas) then writes its own detailed specification, the actual syllabus a school teaches to and is examined against.
If you've ever tried to find "the GCSE History curriculum" and instead found four different specifications from four different boards, each covering different historical periods, you've already run into this layer. It isn't a website error — it reflects a genuine, two-layer structure that is worth understanding properly.
What the National Curriculum actually is
The National Curriculum in England is a statutory framework, set by the Department for Education, that sets out subjects and content that must be taught in maintained (local-authority) schools, organised into Key Stages. Its influence is strongest at Key Stages 1 to 3 — that is, primary school through to age 14. It sets programmes of study for subjects like English, maths, science and others, giving schools a shared baseline for what's covered before students choose their GCSE options.
Crucially, the National Curriculum itself is not the document your child's GCSE exam is written against. It shapes what happens before Year 10 far more directly than what happens during the GCSE course itself.
What actually governs GCSE and A-level content
For GCSEs and A-levels, the Department for Education publishes separate "subject content" documents for each subject — setting out, at a fairly broad level, what must be covered: the required topics, skills and assessment objectives a qualification in that subject has to include. This is deliberately not a detailed teaching syllabus; it's closer to a set of ground rules.
Within those ground rules, Ofqual's qualification and subject-level conditions require any GCSE or A-level in a given subject, from any awarding body, to meet the same subject content — so a GCSE History from AQA and a GCSE History from OCR are guaranteed, by regulation, to share the same required skills and assessment objectives, even though the specific historical periods and case studies they actually teach can differ substantially.
Where the exam board specification comes in
Each awarding body then writes its own specification — the actual, detailed syllabus that a school buys into and teaches from. As AQA's own description of how it develops a specification sets out, this involves consultation with teachers, universities and subject associations, and results in a document covering the exact topics, assessment structure, exam paper format, and required texts or case studies for that board's version of the qualification. This is the document a school's department actually plans lessons from — not the DfE subject content, and not the National Curriculum.
This is precisely why GCSE History looks so different school to school: the DfE subject content requires students to study a mix of British and wider world history across different time periods and develop specific historical skills, but leaves each awarding body to choose which actual periods, events and case studies fill that requirement. One school's GCSE History might cover the Cold War and Elizabethan England; another's, entirely different topics — both valid, both meeting the same DfE subject content, examined by different specifications.
Do academies have to follow the National Curriculum?
No. Academies and free schools — now the majority of English secondary schools — are not legally required to follow the National Curriculum, and have more freedom over what they teach before GCSE. In practice, most still teach a broadly similar curriculum to maintained schools, partly because it prepares students well for GCSE options and partly because many academy trusts choose to follow it voluntarily. Where the system does apply equally to every school, academy or not, is at GCSE and A-level: any school entering students for a GCSE or A-level uses a specification that must meet the same DfE subject content and Ofqual conditions, regardless of what that school's curriculum looked like at Key Stage 3.
The three layers, side by side
| Layer | Who writes it | What it covers | Which age range it mainly governs |
|---|---|---|---|
| National Curriculum | Department for Education | Broad statutory subjects and programmes of study for maintained schools | Key Stages 1–3 (up to age 14) |
| Subject content | Department for Education | Required topics, skills and assessment objectives per GCSE/A-level subject | GCSE and A-level (ages 14–18) |
| Specification | Each awarding body (AQA, Pearson Edexcel, OCR, WJEC/Eduqas) | The detailed syllabus: exact topics, texts, case studies, paper format | GCSE and A-level (ages 14–18) |
Reading down that table shows why a parent can genuinely be looking at the "wrong" document without realising it — a school's GCSE options evening will hand out specification-level detail, but a search for "the National Curriculum" turns up the statutory Key Stage 1–3 document instead, which simply isn't operating at that layer.
A concrete example: why GCSE Maths tiers are identical but the questions aren't
Mathematics is a useful worked example because the DfE's subject content mandates something very specific that every board must follow: GCSE Maths is split into Foundation tier (grades 1–5 available) and Higher tier (grades 4–9 available), and that two-tier structure, along with the required content domains — number, algebra, ratio, geometry, probability, statistics — is fixed by subject content, not left to board discretion. What each board does differ on, within that shared structure, is question style, the specific balance of marks across topics within the permitted range, and the exact wording and context used in problem-solving questions. A school choosing AQA Maths over Edexcel Maths isn't choosing different content coverage in any meaningful sense — it's choosing a house style of paper.
How this differs from a single-ministry system
In several other countries, this two-layer structure doesn't exist, because one body does both jobs. In France, the Ministry of Education sets the national programmes d'enseignement (teaching programmes) directly, and the baccalauréat exam is set against those same programmes by the same ministry structure — there's no separate layer of competing boards each writing their own version of "what a French Literature course should cover." A French parent, in effect, only has one document to look at; an English parent has two, plus whichever specification their child's particular school happens to have chosen.
Devolution adds a fourth complication
Everything above describes England specifically, and that's a deliberate scope choice, because education is devolved and the other UK nations haven't simply adopted England's National Curriculum. Wales has moved away from the old National Curriculum model entirely in favour of its own Curriculum for Wales, overseen by the Welsh Government, with qualifications regulated separately by Qualifications Wales rather than Ofqual. Scotland has its own Curriculum for Excellence and its own qualifications body, the SQA, running an entirely different qualification structure (National 5s and Highers) rather than GCSEs and A-levels at all. Northern Ireland has its own Northern Ireland Curriculum and its own regulator, CCEA Regulation, alongside schools that can also choose GCSEs and A-levels from the England-based boards. A family moving between UK nations, not just between schools within England, can therefore be crossing a curriculum boundary as well as — or instead of — a specification boundary.
Why this two-layer system exists at all
The structure reflects England's decision, discussed further in why the UK has five exam boards, to keep several independent, competing awarding bodies rather than a single state examination authority. The DfE's subject content layer exists specifically to stop that competition from fragmenting standards — every board must meet the same core requirements — while still leaving room for different specifications, textbooks and teaching approaches to compete on their merits.
The takeaway
Two different documents are doing two different jobs. The National Curriculum sets a broad, statutory baseline mainly for Key Stage 3 in maintained schools. GCSE and A-level content is governed by DfE subject content — the shared rules every board must meet — and then made concrete by each awarding body's own specification, which is the actual syllabus a school teaches and a student sits. Knowing which layer you're looking at is usually enough to resolve the confusion.
