Mark schemes in plain words

Mark schemes in plain words: what this page covers

A mark scheme is the grid an examiner works from. It is not a model answer, and treating the two as the same thing is one of the quiet reasons capable pupils plateau in Year 10 and stay there through the spring mocks. Below I explain how we teach a pupil to read the scheme before they write, how the sessions run, what your child brings, and what makes some pupils need more lessons on it than others.

Here is the sort of thing that changes a pupil's habits in a single hour. A three-mark maths question might award one method mark, one accuracy mark and one mark for the correct unit. A pupil who writes the right number with no working can score less than a pupil who shows two steps and slips on the arithmetic, because follow-through marks exist. Until someone shows them the grid, that feels arbitrary. Once they see it, they stop hiding their working.

We work with the pupil's own exam board specification open on the table, whether the lesson happens at home in Bedminster or over video on a Tuesday evening in November.

What a mark scheme actually contains

Schemes for maths and the sciences are usually point-based. Each line carries a code, and the codes are a language your child is expected to read fluently by the summer of Year 11.

• M marks reward a valid method, even when the final answer is wrong.
• A marks reward accuracy, and usually only pay out when the method is sound.
• B marks stand alone, awarded for a correct statement, definition or reading.
• C or Q marks reward communication and quality of written response, often on longer answers.
• Shorthand matters: ft means follow through, cao means correct answer only, oe means or equivalent, ecf means error carried forward, AWRT means any answer which rounds to.

English language, English literature and the longer-answer questions in other subjects use banded schemes instead. There are no single marks to collect. The examiner reads the whole response and places it in a level using descriptors, then decides high or low within that level against the assessment objectives. AO1, AO2 and AO3 carry different weights depending on the question, so a pupil who writes beautifully about a text but never quotes is leaving marks behind, and a pupil who quotes constantly without explaining the effect is doing the same thing in reverse. Schemes for these papers also carry indicative content: a list of what examiners will accept, explicitly not an exhaustive one.

Who this suits, and who it does not

It suits the pupil whose subject knowledge is reasonable but whose marks do not reflect it. Parents often describe this as careless mistakes or running out of time. Frequently it is neither. The pupil is answering the question they think was asked, in the shape they used in Year 7, and the scheme is paying for something else.

It suits Year 10 and Year 11 pupils preparing for GCSE, and it works well with Year 9 pupils who are beginning to sit full papers for the first time. It can also help at A-level, where the same principle applies with longer mark tariffs, and in 11+ preparation for papers where marks are awarded for method rather than only the final answer.

It does not suit a pupil who has genuine gaps in the underlying content. Reading a scheme will not teach someone how to rearrange an equation or what a simile does. Where the gap is knowledge, we say so and we teach the content first. We would rather tell you that in the second lesson than spend a term polishing technique around a hole.

It also fits badly with pupils who want answers handed over. The scheme-reading sessions ask them to mark their own work and defend the marks, which is harder than being told a grade.

How a sequence of lessons runs, step by step

Step one: reverse the paper

We start with a past question the pupil has not attempted. Before they write anything, they read the mark scheme for that question and tell me what the examiner is looking for. Most pupils find this strange for about ten minutes. Then they notice that a four-mark question expects four separate points, and they start counting before they write.

Step two: write to the tariff

The pupil answers the question with the scheme face up. We are training a habit, not testing them. A six-mark explain question gets six distinct, linked points. A three-mark calculation gets the working laid out line by line so the method mark is visible.

Step three: mark it cold, then compare

They mark their own response against the official scheme using a different colour, and we compare their marking with mine. Where we disagree, we go back to the wording of the scheme together. This is where the real learning sits, because pupils are far stricter or far kinder to themselves than an examiner would be, and both errors are informative.

Step four: read the examiner report

Exam boards publish reports after each series describing what went wrong nationally. We read the two or three paragraphs that apply to the question type we are working on. Pupils take these seriously in a way they rarely take a teacher's general advice seriously, because the report is not aimed at them personally.

Step five: rebuild the answer

The pupil rewrites the response under a short time limit, aiming for the marks they missed. We keep both versions in their folder so the change is visible in their own handwriting.

Step six: record it

What we covered goes into the progress report you receive, in plain language, with the question types and the marks the pupil is now collecting that they were not collecting before. You see the work, not just the effort.

What your child brings, and where you stay in control

Your child needs past papers or the question booklets their school uses, the mark scheme that goes with them, and a pen they can mark in a second colour. If the school has not issued schemes, we can work from the published ones for their board. A calculator, a ruler and the relevant specification are useful. We ask that phones stay in another room during the lesson, including online lessons.

You decide how much of the lesson time is spent on scheme work. Some parents want a single exam technique block close to the mocks and the rest of the term on content. Others want scheme-reading built into every session. Both are reasonable, and we will tell you which we think your child needs and why.

You also decide what goes into the progress report and who reads it. If a school teacher needs to know which question types we are targeting, we are happy for you to pass the report on. You can pause, stop or change the schedule at any point, and our coordinator will adjust the tutor match if the working relationship is not right.

What affects the timing and what it costs

No two pupils need the same number of sessions on this, and I will not pretend otherwise. The variables are fairly clear. A pupil sitting one board's maths papers can absorb the point-based scheme in a few lessons. A pupil taking combined science across three exam papers, each with its own tariff conventions, needs longer. English takes longest, because banded marking asks pupils to judge the quality of an argument rather than tick off points.

Frequency matters more than total hours. Weekly sessions with a paper attempted in between beat a fortnightly block. The point at which you start matters too: beginning in September of Year 11 leaves room to change habits before the mocks, while beginning in April leaves time only for the highest-value fixes. Travel affects home lessons, since a tutor visiting you on the far side of the city has a different day than one teaching online. Online lessons remove that variable entirely.

Fees depend on subject, level, lesson length and whether you choose home or online tuition, and the current rate is confirmed when you book. Ask and we will set it out plainly before anything is scheduled. Opening hours are also confirmed at the point of booking.

Questions parents ask

Is reading mark schemes just teaching to the test?

It is teaching to the paper your child will actually sit. They still need the chemistry and the analysis. What changes is that they stop losing marks they had already earned.

My child says the mark scheme never matches what the teacher accepts. Who is right?

Usually both, and this is worth a lesson on its own. Schemes often include an or equivalent clause, and teachers accept alternatives that are consistent with it. We teach pupils to spot those clauses rather than memorise one answer.

Will this help if my child already gets good marks?

Often yes, particularly at the top end. Grade 8 and 9 candidates lose marks in the same places, usually on extended responses where the assessment objectives are unevenly covered.

Do you use the scheme for our exam board?

Yes. We match the tutor to the subject and the board, and the planning is built around your child's specification. Tell us the board when you get in touch and we will confirm the match.

How do I know it is working?

The progress reports show the question types and the marks being collected, and you can see the pupil's marked scripts. We do not predict grades, and we will not promise a particular result. What we can show you is the change in how they answer.
