Does the Science Practical Endorsement Carry Forward When You Resit?

If you already hold a Pass in the practical endorsement for Biology, Chemistry or Physics, you almost certainly do not need to repeat twelve practicals to resit the subject. This page sets out the rule board by board, the paperwork that makes it work, and what it saves you.

Yes, a Pass in the A-Level science practical endorsement carries forward when you resit, it carries forward even if the resit is with a different exam board, and it carries for the lifetime of the specification with no time restriction, provided the entry uses the correct entry code and the same Unique Candidate Identifier and the carry-forward request is made by the entry deadline.

What the Practical Endorsement Is, in One Paragraph

A-Level Biology, Chemistry and Physics each carry a separate practical component called the science practical endorsement. It is assessed by your centre rather than by an examiner, across at least twelve required practical activities, against a set of competencies known as CPAC, the Common Practical Assessment Criteria. It is reported on your certificate as Pass or Not Classified. It does not contribute to your A*–E grade.

The written papers are a different matter. At least 15% of the marks in an A-Level science assess practical skills, and those marks sit inside the ordinary written papers. So the endorsement and the practical content of the exam are two separate things: the endorsement is a yes-or-no line on the certificate, while practical knowledge is examined on paper like everything else.

That separation is the whole reason carry-forward exists. Because the endorsement is not part of the grade, re-sitting the grade does not require re-sitting the endorsement.

Board by Board

The rule is consistent across the awarding bodies, but the entry mechanism and the terminology differ. Always confirm the exact entry code with the centre making your entry.

OCRA Pass may be carried forward and used alongside the grade achieved in re-sitting the exams, even if the resit is with a different exam board.The appropriate entry code for a candidate carrying forward the endorsement, rather than the standard code.
AQAThe science practical result carries forward even if it was awarded by a different awarding body. AQA publishes a table of compatible specifications for Biology, Chemistry and Physics.A carry-forward request, made through the centre, using the same UCI as the original award.

Eduqas / WJECAppears in AQA's published list of compatible specifications for carry-forward purposes.Confirm directly with the centre and the awarding body before the entry deadline.

None of this happens by itself. Carry-forward is a positive act by the centre making your entry, and it is made at the point of entry, not afterwards, and not at results. See our practical endorsement service page for how we handle it.

Why the UCI Is the Thing That Makes It Work

A Unique Candidate Identifier, or UCI, is a thirteen-character code that follows a candidate across schools, colleges and awarding bodies. It is used to make entries and collect results for a student across time and across different exam boards, schools or colleges. The first five characters are the centre number that first allocated it, and it stays with you afterwards.

This matters for carry-forward for a simple reason. A carry-forward request is an instruction to the awarding body to find an existing result and attach it to a new entry. The awarding body finds that result by UCI. If your new entry is made under a fresh UCI, there is nothing to match against, and the endorsement will not appear.

So the first question any centre should ask a science resitter is not "which board?" but "what is your UCI?". If you do not know it, it is on your statement of results or available from the school or college that entered you originally. There is more detail on our guide to UCIs and candidate numbers.

Step by step

How a Carry-Forward Is Actually Done

  1. Confirm What You Hold

    Find your statement of results for the original series. You are looking for the endorsement line, which will read Pass or Not Classified, separately from the A*–E grade. If you cannot find it, the centre that entered you can confirm it, or the awarding body can on request.

  2. Find Your UCI

    Thirteen characters, on the statement of results or held by your original centre. Give it to the centre making your resit entry in writing, and ask them to confirm in writing that they have used it.

  3. Check the Specification Is Compatible

    AQA publishes a table of compatible specification codes across the awarding bodies. If you sat OCR Biology A (H420) and are resitting AQA Biology (7402), the endorsement transfers. Confirm the specific pairing before you rely on it.

  4. Make the Request by the Entry Deadline

    The carry-forward request is made with the entry, not after it. For the Summer 2027 series the standard entry deadline is 21 February 2027. Late entries are possible at an increased fee, but leaving a carry-forward to a late entry is an avoidable risk.

  5. Get the Entry Code in Writing

    Carry-forward uses a different entry code from a standard entry, or a specific transferred-endorsement option. Ask the centre to send you the exact code they have used and check it against the awarding body's published entry codes.

  6. Check the Statement of Entry

    Awarding bodies issue a statement of entry before the exams. Read it. If the endorsement carry-forward is not shown, raise it immediately rather than at results.

What "not Classified" Means, and What to Do About It

The endorsement has two outcomes: Pass, or Not Classified. There is no partial result and no grade. Not Classified means the centre did not judge that you had consistently met the CPAC competencies across the required practicals, often because a candidate moved centres part-way, missed practical sessions, or had an incomplete practical record.

Not Classified is not a fail in the sense of a grade. It does not reduce your A*–E grade, and it does not appear as a mark. It appears as an absence: your certificate records the grade and records that the endorsement was not achieved.

There is nothing to carry forward from a Not Classified. If that is your position, you need to complete the endorsement again, twelve required practicals, assessed by a centre approved to do so. That is a laboratory-based programme, not a paperwork exercise, and it needs to run across the year rather than be compressed into a fortnight.

Some candidates hold the opposite combination: a Pass in the endorsement but a grade they want to improve. That is the cheapest resit in the A-Level system, and the one most often mis-sold.

What Carry-Forward Saves You

Our own published rates. A science resit with a valid carry-forward is charged at the written-paper rate, because that is what is being taught.

Pass carried forward, written papers only£299£375£3,365 across ten months
New endorsement required, laboratory programme£365£995£4,645 across ten months
Endorsement only, papers entered elsewhere£365£650£4,300 across ten months

The difference between the first and second row is £1,280 for a single subject. Across three sciences it is larger again. This is why the carry-forward question should be settled before you enrol anywhere, not after. Our full fee schedule sets out every charge.

Where Providers Get This Wrong

A resitting science student is routinely quoted the science rate, the one that includes a full laboratory programme, when they already hold a Pass that carries forward. Sometimes that is a deliberate way to charge more. More often it is that nobody asked.

We would rather ask and take the smaller fee. If you hold a Pass, we teach and enter you for written papers only, and you pay the written-paper rate. If you hold Not Classified, we will say so plainly and quote the laboratory programme, because that is what you need.

The diagnostic assessment is free and happens before you pay anything. Bring your statement of results to it.

Questions

Questions About Carrying the Endorsement Forward

No, provided you already hold a Pass. A Pass carries forward to a resit and can be used alongside the new grade. You would be re-sitting the written papers only.

If your endorsement was recorded as Not Classified, there is nothing to carry forward and you would need to complete the twelve required practicals again with a centre able to assess them.

Yes. OCR states a Pass may be carried forward even where the resit is with a different exam board, using the appropriate entry code. AQA confirms the science practical result carries forward even if it was awarded by a different awarding body, and publishes a list of compatible specifications across AQA, OCR, Pearson Edexcel and Eduqas.

Check the specific specification pairing before you rely on it, and get the entry code confirmed in writing.

It carries for the lifetime of the specification, with no time restriction. There is no rule that it expires after one year, two years or five years.

The limit is the specification itself. If the specification you originally sat has been withdrawn and replaced, the compatibility table is where you check whether the old result still maps to the new one.

It means the endorsement was not achieved. The centre did not judge that you had consistently met the CPAC competencies across the required practical activities.

It is reported separately from the A*–E grade and does not reduce it. There is no partial result: the endorsement is either Pass or Not Classified.

Yes. The endorsement can be entered separately from the written papers, which is the position for a candidate who holds an acceptable grade but was recorded as Not Classified.

It requires a centre with a laboratory and the ability to assess against CPAC, running the twelve required practicals across the year. Our own charge for the endorsement alone, where the written papers are entered elsewhere, is on the exam fees page.

You can be awarded the A*–E grade without the endorsement, the two are reported separately, and the endorsement does not contribute to the grade. Your certificate would show the grade alongside Not Classified.

Whether that is acceptable depends entirely on where you are applying. Many university science and medical courses require a Pass in the endorsement as a condition of the offer. Check the specific course before deciding this is a route you can take.

No. It is reported separately as Pass or Not Classified and makes no contribution to the grade.

What does affect your grade is practical knowledge: at least 15% of the marks in an A-Level science assess practical skills, examined within the ordinary written papers. Carrying forward the endorsement does not excuse you from learning that material.

Because universities and employers treat the endorsement as evidence that you have worked in a laboratory. Science and medical courses commonly make a Pass a condition of the offer, and a Not Classified on the certificate is visible for the life of the certificate.

It also matters for the written papers, where practical technique, apparatus, error analysis and experimental design are directly examined.

Twelve per subject at A-Level. A centre completing the endorsement must be able to demonstrate that reasonable opportunities were provided to undertake at least twelve appropriate practical activities.

AS Level carries no formal practical endorsement, but AS papers assume six required practical activities and examine them on paper.

CPAC stands for the Common Practical Assessment Criteria. It is the shared set of competencies against which the endorsement is judged, following written procedures, applying investigative approaches, using apparatus safely and correctly, and keeping appropriate records.

The criteria are common across the awarding bodies, which is one reason a Pass transfers between them.

Your Unique Candidate Identifier, the awarding body and specification code of the original award, the series in which it was awarded, and evidence of the Pass, normally the statement of results.

Ask the centre to confirm in writing which entry code they have used, and check it against the awarding body's published entry codes.

It is printed on your statement of results. If you no longer have that, the school or college that entered you holds it, and the awarding body can confirm it on request with identity evidence.

Do not let a centre proceed without it. An entry made under a fresh UCI gives the awarding body nothing to match a carry-forward against.

Yes. It is made with the entry, so the operative deadline is the entry deadline, 21 February 2027 for the Summer 2027 series.

Late entries are accepted for a period afterwards at an increased fee, but a carry-forward attached to a late entry leaves less time to correct an error.

No. A standard entry will not pull an old endorsement through. The centre must make a positive carry-forward request, or select the transferred-endorsement entry option, using a specific entry code.

This is the single most common point of failure. Check your statement of entry when it arrives.

Yes. The result sits with the awarding body against your UCI, not with the school. A closed centre does not remove an awarded result.

You will need your UCI and your statement of results. If both are lost, the awarding body is the route to recovering them.

No, because AS Level carries no formal practical endorsement to carry forward. The endorsement exists only at A-Level.

AS papers do assume six required practical activities, and that practical content is examined on paper, but there is no separate Pass or Not Classified line at AS.

No. The endorsement is per subject. Carrying forward a Chemistry endorsement has no bearing on a Biology entry, and vice versa.

Each subject you resit needs its own carry-forward request against the same UCI.

No. The certificate records the endorsement as Pass. It does not annotate the series or centre in which the endorsement was originally achieved.

This is not a route open to candidates studying in the UK. Pearson states that its International A Levels are not available for candidates studying in the UK, so the question does not arise for a domestic resit.

If you are resitting in England, you are resitting a domestic A-Level, and the carry-forward rules above apply.

The current endorsement was introduced with the reformed linear specifications. Practical work assessed under a legacy modular specification is not the same qualification component and does not map onto the current endorsement.

If your original award predates the reformed specification, assume you need to complete the endorsement and confirm the position with the awarding body before you pay for anything.

For the endorsement itself, yes, there is nothing to assess. But at least 15% of the written-paper marks assess practical skills, so laboratory teaching still improves your paper.

We teach the practical content of the specification to carry-forward candidates as part of the ordinary course, using our laboratory, without charging the endorsement rate.

The centre. The endorsement is centre-assessed against CPAC and confirmed by a declaration from the centre to the awarding body, subject to monitoring visits.

It is not marked by an external examiner and there is no paper to sit.

Ask them to identify the rule they are relying on. OCR and AQA both publish the opposite position, and AQA publishes the compatible specification list.

If the answer is that the centre cannot process a carry-forward. That is a statement about the centre rather than about the regulations, and you should find a centre that can.
