GCSE Maths grade boundaries explained: what they are, how they're set, the real AQA figures for 2022 to 2025, and what you need for a grade 4, 5, 7 or 9.
Grade boundaries are one of the most misunderstood parts of GCSE exams. Understanding them properly can change how your child spends their final weeks of revision.
This guide explains what boundaries are, how they're set, what AQA's published figures actually look like, and how to use them without drawing the wrong conclusion.
Key Takeaways
- Boundaries are set after papers are marked, so nobody knows the 2026 figures until results day, Thursday 20 August 2026.
- On AQA Higher tier in 2025, a grade 4 needed 63 marks out of 240 and a grade 7 needed 164. Both are published figures, not estimates.
- Boundaries rose across 2022 to 2024 mainly because national grading returned to pre-pandemic standards, not because papers got easier. They then held steady in 2025, which suggests that adjustment has worked through.
- A separate effect, the sawtooth, means boundaries drop when a new specification arrives and climb back over roughly three years. It tells you when old boundaries are least reliable as a guide.
- Marks aren't evenly difficult. Early questions carry far more accessible marks than later ones, which is what makes a grade 4 strategy different from a grade 7 strategy.
A grade boundary is the minimum mark needed for a particular grade. Boundaries are set after papers are marked, based on how the whole national cohort performed.
That means they aren't fixed in advance. A hard paper produces lower boundaries because fewer students score highly. An easier paper produces higher ones.
Key Point: Grade boundaries are never announced before an exam. They're published on results day, alongside results. Previous years' boundaries are free on exam board websites and useful for benchmarking, but they won't match the current year exactly.
These are AQA's published subject-level boundaries for GCSE Mathematics (8300), Higher tier, for the June series. Higher tier is marked out of 240 across three papers of 80 marks each.
| Grade | 2022 | 2023 | 2024 | 2025 | 2025 as % |
|---|---|---|---|---|---|
| Grade 9 | 214 | 214 | 219 | 219 | 91% |
| Grade 8 | 185 | 186 | 191 | 191 | 80% |
| Grade 7 | 156 | 158 | 163 | 164 | 68% |
| Grade 6 | 121 | 125 | 129 | 130 | 54% |
| Grade 5 | 86 | 92 | 95 | 96 | 40% |
| Grade 4 | 51 | 59 | 61 | 63 | 26% |
| Grade 3 | 33 | 42 | 44 | 46 | 19% |

Foundation tier is also marked out of 240 and covers grades 1 to 5. If your child is entered for Foundation, the Higher tier figures above don't apply to them.
| Grade | 2022 | 2023 | 2024 | 2025 | 2025 as % |
|---|---|---|---|---|---|
| Grade 5 | 172 | 189 | 186 | 188 | 78% |
| Grade 4 | 135 | 158 | 157 | 160 | 67% |
| Grade 3 | 101 | 117 | 117 | 119 | 50% |
| Grade 2 | 67 | 76 | 77 | 79 | 33% |
| Grade 1 | 33 | 35 | 37 | 39 | 16% |

In a Foundation tier a student needs to get more questions correct for the same grade 1-5 as in the Higher tier. For example, a grade 4 on Higher took 26% of the marks in 2025. The same grade 4 on Foundation took 67%. Questions in a Foundation paper have their difficulty capped, so the average question is much easier than in Higher tier.
Every boundary rose, then settled. The grade 4 line moved most in proportional terms, from 51 marks to 63, a 24% increase in the mark needed for a standard pass.
The 2025 column is the interesting one. Grade 9 didn't move at all, grade 7 went up by a single mark and grade 4 by two. After three years of climbing, boundaries have essentially levelled off. That's what you'd expect once the post-pandemic adjustment has finished working through, and it makes recent years a more reliable guide than they have been since 2019.
Two separate things push boundaries around, and they're often confused with each other.
The 2022 to 2024 rise is mostly this. After the pandemic, 2022 grading was deliberately set between 2021 and 2019 standards as a transition year. In 2023, Ofqual returned national results to pre-pandemic levels. Boundaries climbed as that protection unwound.
This has nothing to do with papers getting easier. It's a national decision about where grades sit. It also explains why 2025 barely moved: once results are back at pre-pandemic levels, there is no further adjustment left to make.
The second reason is structural, and it has a name. When a new specification is introduced, cohort performance drops, then recovers over the following years as teachers and students get familiar with it. Plotted over time it makes a jagged, saw-toothed shape.
Ofqual research splits it into two parts: a disruption effect when a specification first changes, driven by teachers being new to the content and having no past papers or exemplar material, and an enhancement effect as resources, exemplars and familiarity accumulate (Newton, What Is the Sawtooth Effect?, Ofqual, 2020).
A study of English secondary assessments used grade boundary changes themselves as a proxy for performance, and found it takes roughly three years on average for a cohort to become familiar with a new set of exams (Cuff, Meadows and Black, Assessment in Education, 2019).
The practical consequence: prior-year boundaries are least reliable in the first years of a new specification, and most reliable once one has been running for a while. The current GCSE Maths specification has been running since 2017, so we're in the stable part of the curve.
Previous boundaries are published free by every exam board: AQA, Pearson Edexcel and OCR. Here's how to use them properly.
One caution on step 3. Boundaries shift year to year, so treat a prior-year boundary as a rough marker rather than a target line. Being three marks above last year's grade 7 is not the same as having a grade 7.
For students at risk of missing a grade 4, the approach should be narrow rather than general.
The maths here is encouraging. On Higher tier in 2025, a grade 4 needed 63 marks out of 240. That's roughly 21 marks a paper, and the early questions on each paper carry far more of them than the later ones.
GCSE results are published on Thursday 20 August 2026. If your child doesn't get the GCSE Maths grade they need, there are clear routes. We cover them in full, with deadlines and what the Ofqual data says about each, in resit or remark: your options after results day. In brief:
Whichever route applies, the revision principles don't change. Our parents' guide to GCSE Maths covers how to support without needing to know the curriculum yourself, and why revision isn't working explains the revision techniques most students get wrong.
On AQA Higher tier in 2025, a grade 7 needed 164 marks out of 240, which is 68%. It was 163 in 2024, 158 in 2023 and 156 in 2022. Expect roughly two thirds of the marks, but treat that as a benchmark rather than a guarantee, because boundaries are set after marking each year.
No. AQA, Pearson Edexcel and OCR each set their own boundaries for their own papers, based on how their cohort performed. Always use the boundaries for the board your child is actually entered with.
Foundation papers cover less demanding content, so students score more marks on them. A grade 4 on AQA Foundation took 160 marks out of 240 in 2025, against 63 on Higher. Same grade, very different mark requirement, because the papers are not the same difficulty.
On results day, Thursday 20 August 2026. Boundaries cannot be published earlier because they're set after all papers are marked and the national performance is known.
Yes. If a paper proves harder than intended, boundaries fall so that students aren't penalised for sitting a difficult version. This is the mechanism behind the sawtooth effect, where boundaries drop when a new specification is introduced and recover as familiarity builds.
