An approved exam centre is one an awarding body — AQA, OCR, Pearson Edexcel, WJEC/Eduqas or CCEA — has authorised to run its exams. That's all "approved" means: the centre has met the board's requirements for secure exam administration and can legitimately offer that board's qualifications. It does not mean the centre accepts private candidates. Those are two separate questions, and conflating them is the single most common source of confusion for families starting this process.
Understanding the distinction properly will save you time, because it tells you exactly what to ask when you contact a centre.
Two separate questions, not one
When you're checking whether a centre could work for your child, you're really asking two independent things:
- Is this centre approved by the right awarding body, for the right specification? A centre might run AQA GCSEs brilliantly but have no approval at all for Pearson Edexcel A-levels — approval is granted board by board, and sometimes subject by subject within a board.
- Is this centre willing to accept a private candidate — a student who isn't enrolled there? This is a business and capacity decision the centre makes for itself. Plenty of fully approved centres, including many excellent schools, only enter their own students and decline private candidates entirely.
A centre can be a "yes" on the first question and a firm "no" on the second. Both need checking, separately, before you get anywhere near booking an exam.
Who approves a centre, and what that involves
Each awarding body runs its own approval process, checking things like secure storage for exam papers, appropriately invigilated exam rooms, and a named exams officer responsible for administration. Because JCQ — the Joint Council for Qualifications — coordinates shared regulations across the boards (things like exam timetabling and malpractice rules), an approved centre generally follows one consistent set of conduct standards regardless of which board's exam is running in the room. But the approval itself — the decision to let a centre offer a given specification — sits with the individual board.
This is why AQA, OCR and Pearson Edexcel each publish their own private-candidate guidance pages: each board manages its own list of approved centres and its own entry process, even though the exams themselves happen under shared JCQ conduct rules.
A worked example: A-level Chemistry and the practical endorsement
Approval status matters most sharply once you look at a subject with a practical component. A-level Chemistry's written papers — the theory exams — are entirely sittable by a private candidate through any centre approved by the relevant board for that specification. The science practical endorsement, reported separately from the overall grade as Pass or Not Classified, is a different matter: it requires a candidate to be directly observed completing a defined set of practical activities (CPAC — Common Practical Assessment Criteria) by a teacher at an approved centre, over the course of the two-year study. A centre approved to run the written A-level Chemistry papers is not automatically equipped, or willing, to supervise and assess that practical component for an external candidate — it needs lab access, trained staff to observe and sign off the work, and a real time commitment spread across the course, not a single exam day.
This is why the practical endorsement is described elsewhere in this cluster as the single biggest blocker private candidates face in the sciences — see science-practical-endorsement-for-private-candidates for the full picture, including what it means for a UCAS application if a candidate ends up without one. The point for this article is narrower: when you ask a centre "are you approved for this specification?", for a science A-level that isn't actually one question — it's two, and a centre can answer yes to the written exams and no, or "not for external candidates," to the practical endorsement.
The exams officer: who you're actually trying to reach
Every approved centre has an exams officer — the person who manages entries, communicates with awarding bodies, and runs exam logistics day to day. When you contact a centre about private-candidate entry, the exams officer is who you want, not general admissions or reception.
A reasonable first email or call to an exams officer should cover:
| Ask | Why it matters |
|---|---|
| The exact specification and awarding body (e.g. "AQA GCSE Combined Science, 8464") | Approval and entry both depend on the exact code, not just the subject name |
| Whether the centre accepts private candidates for that specification | Approval and willingness are separate — confirm both |
| What their entry deadline is for the relevant series | Missed deadlines are one of the most common, and most avoidable, mistakes in this whole process |
| What their own administration fee is, on top of the board's entry fee | See what-exam-centres-charge-private-candidates — this varies widely by centre |
| For a science practical: whether they can supervise and assess CPAC for an external candidate | Many centres that accept private candidates for written papers still can't offer this |
Getting a clear, specific answer to each in one exchange is a good sign you've found a centre that's genuinely set up for this. A vague or delayed answer, especially on the deadline question, is worth treating as a warning sign rather than pressing ahead regardless.
The mistake worth naming directly
The most costly version of this mistake isn't picking a centre that turns out to be unwilling — that's disappointing but recoverable, since you simply try another centre. It's assuming that because a centre is approved and willing for the written exams, it must also cover everything a specification requires, and only discovering the gap — usually around a practical or coursework component — once it's too late in the course to arrange an alternative. Ask about non-exam assessment explicitly, in the same conversation where you confirm approval, rather than treating it as a separate question for later.
Why not every approved centre accepts private candidates
Taking on external candidates adds real work for a centre — extra invigilation, extra paperwork, extra exam-room capacity on days that are already at their busiest — for students the centre gets no ongoing relationship or funding from. Many schools, understandably, prioritise their own students and don't have the spare capacity or the motivation to take on others. This isn't a reflection on the quality of the school; it's a straightforward resourcing decision.
Because of this, a specific type of centre has grown up around private candidates specifically: dedicated private-candidate exam centres, which exist mainly or entirely to serve home-educated students, resitters and adult learners, often across several boards and a wide range of subjects. These are usually the most reliable starting point for a family with no existing relationship to a school, precisely because taking private candidates is their core purpose rather than an occasional favour.
Is there a public list of centres that accept private candidates?
This is a genuinely useful question this article can't fully answer, and it's worth raising directly with each board rather than assuming an answer. Some awarding bodies maintain centre-search tools or contact points aimed at private candidates, but coverage and detail vary, and none of them function as a complete, guaranteed-current directory of every centre willing to take external candidates for every subject. In practice, most families still end up building their own shortlist by combining a board's own guidance with direct enquiries to individual centres — particularly dedicated private-candidate centres, which tend to be easier to find precisely because taking external candidates is their main purpose rather than an occasional exception. Ofqual, as the regulator, doesn't maintain or endorse any such list either; its role is regulating the boards and centres, not directory services for families.
What this means practically
Before you get attached to any particular centre, confirm both pieces — approval for the right board and specification, and willingness to take a private candidate — directly with the exams officer. Don't assume either from a centre's general reputation or the fact that it's a well-known school. choosing-your-own-exam-centre covers how to search for and evaluate centres once you understand what you're checking for.
The bottom line
"Approved" tells you a centre is authorised to run a particular board's exams — nothing more. Whether that centre will take your child as a private candidate is a completely separate, centre-specific decision, and the only way to know is to ask the exams officer directly. Always confirm current arrangements with the centre itself, since capacity and policy can change from one exam series to the next.
