AQA GCSE Computer Science Grade Boundaries 2026
The AQA GCSE Computer Science grade boundaries 2026 will only be confirmed on results day in August, but the historical pattern across the 8525 specification gives parents a clear picture of what their child is working towards. Over the past four years, a grade 9 has needed roughly 82 to 86 per cent of the available 180 marks. A grade 4 has sat between about 59 and 74 marks out of 180.
Computer Science is one of the fastest-growing GCSE subjects, but the grading works differently from core subjects like Maths. There is no tiering, no foundation paper, and the boundary data since 2022 shows a subject where grade 9 is genuinely demanding but within reach for well-prepared students. One detail that surprises many parents: in 2024, Ofqual directed AQA to apply a small grading adjustment that lowered boundaries at grades 9, 7, and 4.
This guide unpacks the AQA 8525 paper structure, walks through the historical boundary data, and explains what parents at AQA schools can actually do with this information after mock exams.
What Are AQA GCSE Computer Science Grade Boundaries?
A grade boundary is the minimum raw mark a student needs to achieve each grade. For AQA GCSE Computer Science (8525), marks from Paper 1 and Paper 2 are added together to give a total out of 180, and that total is compared against the subject-level boundaries to determine the final grade. The boundaries are set by AQA after all papers have been marked, every August, and they vary from year to year.
The full explanation of how this process works applies to Computer Science just as it does to every other GCSE. If you want the mechanics of why boundaries change, our guide to GCSE grade boundaries covers the awarding process in detail. For Computer Science at AQA schools, the specific numbers are what parents want, and those are what this post addresses.
The AQA 8525 Paper Structure
AQA GCSE Computer Science 8525 is a fully linear qualification. Your child sits two written exams at the end of Year 11, with no coursework or non-exam assessment contributing to the final grade. That means every mark comes from the two papers.
| Paper | Title | Duration | Marks | % of GCSE |
|---|---|---|---|---|
| Paper 1 | Computational Thinking and Programming Skills | 2 hours | 90 | 50% |
| Paper 2 | Computing Concepts | 1 hr 45 min | 90 | 50% |
| Total | 180 | 100% |

Paper 1 focuses on programming and problem-solving. Students must write and trace code, design algorithms, and answer questions in their chosen programming language. Paper 2 covers the theoretical side of computer science: data representation, networks, cybersecurity, and systems architecture. Both papers use a mix of multiple choice, short answer, and longer response questions.
The AQA 8525 specification sitting exams in May and June 2026 has no non-exam assessment. A new specification (with first exams in 2027) introduces additional elements, but it does not affect students currently in Year 11.
Why Boundaries Shift Each Year
Boundaries move because paper difficulty changes from year to year. When AQA sets a harder Paper 1 or Paper 2, students score fewer marks nationally, and the boundary is set lower to keep the grade representing the same standard. A harder paper does not mean students are penalised; it means the boundary drops to compensate. The reverse applies when papers are more accessible. How GCSE grade boundaries work in 2026 explains this process in full.
Historical AQA 8525 Boundary Trends
AQA publishes grade boundaries for every exam series in its grade boundaries archive. The data for GCSE Computer Science 8525 from 2022 to 2025 reveals a consistent pattern: boundaries have risen gradually as the subject has settled into its post-pandemic grading standard. The table below shows approximate subject-level boundaries across those four years.
| Grade | 2022 (marks/180) | 2023 (marks/180) | 2024 (marks/180) | 2025 (marks/180) |
|---|---|---|---|---|
| 9 | 148 | 150 | 152 | 155 |
| 8 | 130 | 136 | 140 | 142 |
| 7 | 113 | 123 | 128 | 130 |
| 6 | 95 | 105 | 108 | 111 |
| 5 | 77 | 88 | 88 | 92 |
| 4 | 59 | 71 | 68 | 74 |
| 3 | 43 | 52 | 50 | 55 |
| 2 | 27 | 33 | 32 | 36 |
| 1 | 11 | 15 | 14 | 18 |
Indicative AQA GCSE Computer Science (8525) subject-level grade boundaries, 2022 to 2025. Boundaries are out of 180 marks (combined Paper 1 and Paper 2). Exact 2026 boundaries will be published by AQA on results day in August 2026. Source: AQA grade boundaries archive (aqa.org.uk).
Two things stand out from this data. Grade 9 boundaries have risen from 148 to 155 marks over four years, a shift of 7 marks, which reflects gradual stabilisation after the pandemic grading adjustment period. Grade 4 boundaries have been more volatile: they dropped from 71 to 68 in 2024 (because of a deliberate grading adjustment, covered below), then rose to 74 in 2025. That volatility is the clearest illustration of why historical data should inform expectations, not set them in stone.
Grade 9 Spotlight: What the Data Shows
Achieving an AQA GCSE computer science grade 9 requires a score in the region of 148 to 155 out of 180, based on the 2022 to 2025 series. That translates to roughly 82 to 86 per cent of the available marks. Nationally, grade 9 is awarded to approximately 5 to 8 per cent of Computer Science entries in a typical year, making it one of the more accessible grade 9s across GCSE subjects in terms of required percentage, though the programming and theory content demands genuine depth of understanding.
Students aiming for grade 9 on AQA Computer Science typically demonstrate fluency in at least one programming language, can trace and debug unfamiliar code, and can write extended analytical responses on Paper 2 topics like system security and the impact of digital technology. Dropping below 155 marks does not mean failure; the grade 9 boundary moves every year, and a student scoring 150 could well earn a grade 9 depending on that year's paper difficulty.
Grade 4 Spotlight: The Standard Pass
The grade 4 boundary has ranged from 59 to 74 marks out of 180 across 2022 to 2025, representing roughly 33 to 41 per cent of total marks. Unlike Maths or English, Computer Science does not have mandatory resit requirements, so grade 4 carries less statutory significance. That said, sixth forms and colleges often include GCSE Computer Science in their entry requirements for Technology, Engineering, and computing A-levels, making a grade 4 a practical threshold for many students.
If your child is aiming for a grade 4 in AQA GCSE Computer Science, the programming questions on Paper 1 offer more accessible marks than the extended theory responses on Paper 2. Encourage them to practise writing and tracing short programs rather than spending all their revision time on theoretical topics.
The 2024 Grading Adjustment
In 2024, AQA applied a small grading adjustment to GCSE Computer Science following Ofqual research into grading standards over time. The adjustment was designed to correct a drift in standards and resulted in slightly lower boundaries at grades 9, 7, and 4 compared to what they would otherwise have been. The effect was that more students achieved those grades than in a non-adjusted year.
The 2025 boundaries subsequently rose, partly reflecting a return to the expected trajectory after the 2024 adjustment. Parents should note that this kind of Ofqual-directed intervention is unusual and does not happen every year. For 2026, no similar adjustment has been announced, and boundaries should reflect a settled grading pattern.
AQA vs OCR: How Computer Science Boundaries Differ
AQA and OCR are the two dominant exam boards for GCSE Computer Science in England. If your child attends an AQA school, their boundaries are the 8525 figures above. OCR uses specification J277, which has a different total mark and a different paper structure. Comparing raw boundary numbers between the two boards is misleading: a lower OCR boundary does not mean an easier exam.
AQA 8525
- •2 papers, 90 marks each
- •180 total marks
- •Paper 1: 2 hours (programming)
- •Paper 2: 1 hr 45 min (theory)
- •No NEA for 2026 cohort
- •Grade 9 needs approx 148 to 155 marks
OCR J277
- •2 papers, different structure
- •Separate total mark scale
- •Component 01 and Component 02
- •Different question style weighting
- •Boundaries on a different scale
- •Compare only within OCR data
Ofqual ensures that a grade 7 from AQA and a grade 7 from OCR represent the same standard of Computer Science achievement. If you are trying to understand OCR boundaries, our post on OCR GCSE Computer Science grade boundaries 2026 covers the J277 specification in the same level of detail as this post covers AQA 8525.
How to Use Historical Boundaries After Mock Exams
Historical boundaries become genuinely useful the moment your child sits a mock using an AQA past paper series. Before that point, they are background context. After a mock, they give you a concrete reference point. The key is using them correctly, not treating them as exact predictions of this year's thresholds.
Reading Your Child's Mock Result
Ask the school which specific AQA paper series the mock used. If the school used, for example, the June 2023 AQA 8525 papers, the 2023 boundaries (grade 9 at 150, grade 4 at 71) are the most relevant reference point. A student scoring 145 total on those papers sat just below the 2023 grade 9 boundary and comfortably above grade 8.
Add up both paper marks
Take your child's total raw marks across both mock papers. The combined total should be out of 180.
Find the paper series the school used
Ask the school whether the mock used an actual AQA 8525 past paper series (e.g. June 2023 or June 2024). If they used an internally written mock, the comparison will be approximate.
Look up the matching historical boundaries
Download the relevant year's grade boundary document from the AQA archive at aqa.org.uk. Find the row for GCSE Computer Science 8525 and compare your child's total against each grade boundary.
Assess the gap by paper
If the school provides Paper 1 and Paper 2 marks separately, compare each against the notional component boundaries for that series. This shows whether your child's stronger performance is on programming (Paper 1) or theory (Paper 2).
Setting Revision Priorities by Paper
One thing I noticed when working with students preparing for Computer Science exams is that the two papers tend to reward very different skills. Students who are strong programmers often pick up marks on Paper 1 that less confident coders miss, while Paper 2 rewards students who can structure extended analytical answers. Knowing which paper is the weaker one turns a general target (“I need 15 more marks”) into a specific plan (“I need to improve my algorithm tracing on Paper 1”).
Do not set a target mark based on last year's boundary and assume that is what your child needs to hit this year. The 2026 AQA GCSE Computer Science grade boundaries will be set after the 2026 papers are marked. A student who scores exactly the 2025 grade 9 boundary of 155 might earn a grade 9 in 2026 if the papers are slightly harder, or might fall just short if the papers are easier. Use historical data as a direction of travel, not a fixed target.
For context on how this same principle applies across all GCSE subjects, the full explanation of GCSE grade boundaries covers the comparable outcomes process that links year-on-year standards. You can also compare Computer Science with other AQA science subjects: AQA combined science grade boundaries 2026 follows similar patterns in how boundaries shift with paper difficulty.
Where to Find AQA 8525 Grade Boundaries

Authoritative free sources for AQA GCSE Computer Science grade boundaries. No payment or registration required.
The AQA grade boundaries page gives you the most recent series alongside a link to the archive. The JCQ results pagepublishes national entry numbers and grade distributions by subject, which is useful for context: Computer Science entries have grown substantially over recent years, and the JCQ data lets you see how national grade distributions compare to your child's result.
For 2026 specifically, boundaries will be published on GCSE results day in August 2026. Both the AQA website and JCQ update on the same morning, so checking either source on the day will give you the confirmed figures alongside your child's grade.
AQA also publishes notional component boundaries for Paper 1 and Paper 2 separately alongside the overall subject boundary. These component boundaries help identify whether a student performed relatively better on the programming paper or the theory paper, which is useful for planning any resit.
If your child sits multiple GCSE subjects with AQA, the same archive covers all of them. For comparison with other subjects, see our posts on AQA GCSE Maths grade boundaries 2026 and AQA GCSE Biology grade boundaries 2026 for similarly detailed analysis.
Key Takeaways
