Reading a mark scheme with your child

Mark schemes are written for examiners, not for families, which is why the first ten minutes with one usually feel like reading a legal contract. Used properly, though, a scheme is the most precise piece of feedback your child will get all year. It shows exactly where the marks sat on a question, and whether the ones they missed were for knowledge, method or careful reading of the question. This page covers how to open a scheme with a Year 10 or Year 11 pupil, how to mark one question without an argument, and what to do with what you find.

What a mark scheme is, and what it cannot tell you

Each GCSE paper in England and Wales is set by an awarding organisation, and every board publishes a mark scheme once the exam series has finished. AQA, Edexcel, OCR and WJEC Eduqas all put them online, free, as PDFs. They are written for people marking thousands of scripts, so the language is clipped and repetitive on purpose.

The limits matter as much as the contents. A scheme tells you how marks were awarded on that paper in that series. It does not tell you how many marks your child needs for a grade 6, because grade boundaries are decided after the papers are marked, and they are published separately. It also does not describe what a fully developed answer looks like. For that, read the examiner report issued alongside the scheme, which summarises what candidates did well and where large numbers of them dropped marks.

Match the paper and the series before you print anything. A scheme from an earlier year can look almost identical to the current one and then treat question nine completely differently. Check the front page for the paper code, the series and the version number, then check that your child's question paper carries the same code. Five minutes here saves a wasted evening.

Get the right documents on the table first

Do this in daylight, at the kitchen table, and not at ten o'clock the night before a school assessment. You need four things in front of you:

• The question paper your child actually sat, or a past paper they have attempted at home.
• Their written answer in their own handwriting, with all working shown.
• The mark scheme for that exact paper and series.
• The examiner report for the same series, if the board published one.

Keep printed copies if you can. A parent in Fishponds told me she now keeps a shallow plastic box with the schemes for each subject in it, so nobody has to scroll through a phone looking for a file at the wrong moment. That small piece of tidiness removes a surprising amount of friction, and friction is usually what turns marking into an argument.

The vocabulary you will meet on the page

Mark schemes are written in shorthand. A handful of terms do most of the work, and once your child recognises them the page speeds up considerably.

• AO1, AO2, AO3, AO4: the assessment objectives. Every subject divides its available marks between them, and the scheme shows the split for each question.
• M, A, B: method, accuracy and independent marks, used heavily in maths and the sciences. A method mark rewards the correct approach even when the final number is wrong.
• ft or ecf: follow through, also called error carried forward. A pupil who slips early can still collect later marks if the method continues correctly from the wrong figure.
• cao: correct answer only. No method mark is available on that part.
• oe: or equivalent, which means a differently worded answer still earns the mark.
• Accept, ignore, do not accept: instructions to the examiner. “Ignore” means an extra detail is not penalised. “Do not accept” means it is wrong, however sensible it sounds.
• Levels of response: numbered bands, used for extended writing in English and similar subjects.
• Indicative content: a list of what candidates might say. It is not a checklist, and no answer is expected to contain every bullet.

The at-home routine, step by step

This takes about forty minutes and works best with one question at a time. A four-mark question is plenty for a first attempt.

1. Choose the question. Pick something your child answered at least a week ago, so the answer is theirs rather than fresh from a lesson. Whole-paper marking belongs to a different session with a different purpose.
2. Ask them to mark it first, before they see the scheme. Their job is to write a mark at the side of each point they think they made, and to say out loud where they believe the marks were. This single step shows how well they understand what examiners reward.
3. Open the scheme together and award the marks line by line. Read each line aloud. Say which line gives which mark. Your child holds the pencil and writes the total; you read the document, not the verdict.
4. Compare their prediction with the awarded mark. The gap is the interesting part. If they expected four and got two, the problem is usually the way they read the question rather than what they knew when revising.
5. Write the lost mark into a log with one category. Content gap, misread question, method slip, or timing and presentation. A cheap notebook works. The log becomes the revision plan.
6. Agree one change for the next attempt. Write it at the top of the page in a sentence they choose themselves. “Underline the command word first” is a good one. If you make five changes at once, none will stick.

Reading a levels-based scheme without guessing

English language, English literature and any extended writing are marked with level descriptors rather than a list of points. The examiner reads the whole answer, picks the band that fits best, then decides whether it sits at the top or the bottom of that band.

Do not try to reconstruct the examiner's exact judgement at home. Instead, read two bands side by side: the one your child's answer would reach, and the one above it. Find the phrase in the higher band that their answer lacks. It is often a single quality, such as a judgement about effect, a range of references across the text, or comment on structure rather than language alone.

Then look at the assessment objective split printed for that question. An essay might place most of its weight on analysis of the text and rather less on context, which means a pupil who spends two paragraphs on the writer's background has spent effort where fewer marks live. That is a technique problem with an obvious fix, and the scheme is the thing that proves it. Say it out loud: the scheme says so. That takes the argument out of your mouth and puts it on the page.

Reading a points-based scheme: where maths and science marks hide

Maths and the sciences use mark-by-mark schemes, and the marks are more generous than most pupils expect. Take a two-mark question asking a pupil to solve 3(x + 5) = 36. The scheme typically awards a method mark for expanding the bracket or for dividing both sides by three, and an accuracy mark for x = 7.

A candidate who expands the bracket correctly, subtracts fifteen from both sides and then divides by three, but writes 7.5 as the final figure, has still shown the examiner enough method to collect the method mark even though the last line is wrong. That is the sort of thing a pupil needs to see for themselves. It changes how they behave in the exam when they get a nasty number.

Three habits follow from reading schemes in these subjects. Working must be written down, because unwritten work earns nothing regardless of what was in the pupil's head. Units and rounding instructions in science carry their own marks, so a correct number without the unit can lose one. And when a pupil reaches a blank space in a mock, the scheme usually shows a mark available for a first step, which is worth more than the empty space they left.

Sorting lost marks into four buckets

By the time you have marked two or three questions, patterns appear. Put every lost mark into one of four buckets, because each one leads to different revision.

• Content gap. They did not know the fact, formula, quotation or case. This is the only bucket that revision notes genuinely solve.
• Misread question. They answered a different question, missed a command word, or stopped before the final instruction. The fix is habit, not knowledge.
• Method slip. The approach was right, the execution was not: a sign error, a lost unit, a mislabelled axis.
• Timing and presentation. Rushed final answers, unlabelled diagrams, an essay that stops mid-point when the time ran out.

In my experience as a classroom teacher, a large share of the marks lost on a first past paper sit in the last three buckets rather than the first. That is encouraging, because those are fixable within weeks. It also explains why two pupils who know roughly the same amount can end up several grades apart.

What the examiner report adds that the scheme does not

The examiner report is a short document written after the marking, describing what candidates did well and what went wrong across the cohort. It frequently names the exact errors that cost marks that year, such as an unlabelled diagram, an unreferenced source, or a calculation left in the wrong units.

Read it once yourself, then read the two or three paragraphs relevant to your child's weakest question with them. A sentence like “many candidates did not read the final instruction” is more persuasive coming from an examiner than from a parent on a Sunday afternoon.

Keeping it from turning into an argument

The usual failure is timing and tone, not the marking. A few ground rules help.

• Your child holds the pencil and writes the marks. You read the document.
• Mark the answer, never the person. “This line earns the mark” is a different sentence from “you always do this”.
• Cap the session at about twenty minutes per question, then stop, even if you are partway through.
• Do not mark a paper on the same evening as a difficult day at school.
• Leave one session a month untouched. Nobody marks well when they are tired.

If the answer is unrecognisable, or the pupil cannot remember what they meant, close the folder and move on. Take the question to a subject teacher or a tutor instead. There is no prize for finishing the scheme.

When it is worth bringing in a subject specialist

Some questions need someone who marks this material regularly. A levels-based English answer, in particular, is hard to band confidently at home, and a wrong diagnosis sends revision in the wrong direction for weeks.

We run one-to-one maths, English and science tuition for pupils aged 7 to 18, at home or online, with DBS-checked qualified tutors. Many of our tutors are current secondary school teachers, and a coordinator matches each pupil to a tutor who knows the exam board specification for the exams they are sitting. Lessons are planned around that specification, so the mark scheme your child is reading belongs to the paper they will actually sit. Parents receive progress reports that tie back to the same categories you have been logging at the kitchen table.

If you would like a second pair of eyes on a set of answers, call +44 117 0451935 or email [email protected]. You can also write to us at 209 Kings Road. Ask about a first assessment lesson and bring the marked paper with you.

A printed four-mark question and its matching scheme can teach your child more about exams than another hour of highlighting notes. Let them mark it first, read the lines aloud together, and write down the one thing to change next time. That is the whole method, and it takes half an hour and some printer ink.
