A-Level Grade Boundaries Explained: A Parent’s Guide
If your child is heading into sixth form or already studying A-Levels, grade boundaries are one of those topics that sounds straightforward but catches nearly every parent off guard. Unlike GCSEs, which use the 9 to 1 number system, A-Levels still use A* to E letter grades. And the raw marks needed for each grade? They change every single year.
From conversations with hundreds of parents during my time in the tutoring industry, the biggest source of anxiety was not the exams themselves. It was the uncertainty: “My daughter thinks she got 68% on her Chemistry paper. Is that an A?” The honest answer is always the same: nobody knows until results day. That uncertainty is by design, and understanding why actually makes the whole process less stressful.
This guide explains exactly how A-Level grade boundaries work, why they shift, how UCAS tariff points fit in, and what you can practically do to help your child through results day.
The A-Level Grading Scale
The A-Level grading system is simpler than the GCSE 9 to 1 scale. There are six pass grades and one fail category:
| Grade | Meaning | UCAS Points |
|---|---|---|
| A* | Exceptional performance (top tier) | 56 |
| A | Excellent understanding across the specification | 48 |
| B | Strong knowledge with some areas of real depth | 40 |
| C | Competent understanding of most content | 32 |
| D | Some understanding, with noticeable gaps | 24 |
| E | Basic understanding (minimum pass) | 16 |
| U | Ungraded (below minimum standard) | 0 |

Where A* Came From
Before 2010, the highest A-Level grade was simply A. The problem was that a growing number of students were achieving A grades, making it difficult for universities to differentiate between a very good student and a truly exceptional one. Ofqual introduced A* specifically to separate the top performers within what had been a single grade band.
To achieve an A*, a student must first meet the grade A boundary overall and then reach an additional, higher threshold on the A2 (second-year) papers specifically. This means A* reflects sustained excellence across the hardest parts of the course, not just a strong start in Year 12.
What U Means
U stands for Ungraded (sometimes called Unclassified). It means the student did not reach the minimum standard for a grade E. A U is not recorded on the UCAS application, and it earns zero tariff points. If your child receives a U, it is worth understanding whether they were close to the E boundary, as a remark could potentially bring them up.
A-Levels use A* to E (letters), not 9 to 1 (numbers). There is no equivalent of the GCSE “strong pass” at grade 5. At A-Level, any grade from A* to E is a pass, and the specific grade required depends entirely on what your child wants to do next.
How A-Level Grade Boundaries Are Set
A-Level grade boundaries are the minimum raw marks needed to achieve each grade on each paper. They are not decided before the exam, not published during the exam series, and not based on fixed percentages. They are determined after all papers have been marked, through a rigorous process overseen by Ofqual (the Office of Qualifications and Examinations Regulation).
The Awarding Process
Each exam board (AQA, Edexcel/Pearson, OCR, WJEC) runs its own awarding process for every subject. It works in three stages:
Senior examiner review
Experienced examiners look at a sample of scripts that fall around the key grade boundaries. They compare the quality of work with what was expected at that boundary in previous years.
Statistical analysis
The exam board analyses the full mark distribution for the cohort: how many students scored at each mark, where natural clusters appear, and how the distribution compares with prior years.
Comparable outcomes
Ofqual uses the principle of comparable outcomes to ensure that a similarly able cohort achieves a similar grade distribution year on year. This prevents one year group being unfairly advantaged or disadvantaged by a particularly hard or easy paper.
Final boundary confirmation
Ofqual reviews the proposed boundaries across all boards to check consistency. Only after this sign-off are the boundaries locked in and published on results day.
Why Grade A Is Set First
In A-Level awarding, the grade A boundary is the anchor point. Exam boards set grade A first because it is the most stable reference point: it represents a clear standard of work that senior examiners can reliably identify. Once grade A is fixed, the boundaries for B, C, D, and E are calculated proportionally based on the mark distribution. The A* boundary is then set separately, requiring not just the overall A mark but an additional threshold on the A2-only papers.
At GCSE, the anchor grades are 7 (equivalent to the old A) and 4 (equivalent to the old C). At A-Level, only grade A is the primary anchor. The rest are derived from it. This is why A-Level grade boundaries can feel less predictable, because one anchor drives the entire scale.
Why Boundaries Change Every Year
This is the single most misunderstood aspect of A-Level grading. Parents who remember their own A-Levels often assume there is a fixed pass mark, perhaps 40% for an E or 70% for an A. There are no fixed percentages at A-Level. The boundaries move every year, deliberately, to keep standards consistent.
A Harder Paper Means Lower Boundaries
The logic works like this: if this year's Chemistry Paper 2 was harder than last year's, students will generally score fewer marks. Without boundary adjustments, grades would drop unfairly. So the exam board lowers the boundary: fewer marks are needed for the same grade. The reverse happens too: an easier paper means higher boundaries.
Harder Paper Year
- •Students score lower on average
- •Boundaries are set lower to compensate
- •Grade distribution stays comparable to previous years
- •Students are not penalised for harder content
Easier Paper Year
- •Students score higher on average
- •Boundaries are raised to maintain standards
- •Grade distribution stays comparable to previous years
- •Students are not gifted grades for easier content
This is why telling your child “you need 75% for an A” is not helpful. In some years, 72% might be enough. In others, 78% might be needed. The only reliable strategy is to maximise marks across all papers and let the boundaries fall where they fall.
When your child comes home from an exam saying “it was really hard,” that is not necessarily bad news. A harder paper means lower boundaries. Encourage them to focus on the next paper rather than dwelling on how a previous one felt.
UCAS Tariff Points
Every A-Level grade converts to UCAS tariff points, which universities use alongside or instead of specific grade requirements. The UCAS tariff calculator converts grades from A-Levels, BTECs, and other qualifications into a single points total.
Grades vs Points: Which Matters?
Most competitive universities (Russell Group and similar) specify grade requirements rather than points. An offer of AAB means exactly those grades, not “any combination totalling 136 points.” However, many other universities, particularly for less competitive courses, make offers in tariff points instead. This is especially common where students are mixing A-Levels with other qualifications like BTECs.
One thing I learned from working with families: parents often underestimate how important the specific grades are for competitive courses. A student with A*AC (136 points) and a student with AAB (136 points) have the same tariff total, but only the second meets an AAB offer. If your child has a specific university in mind, always check whether the offer is grade-based or points-based.
| Combination | Total Points | Meets AAB Offer? |
|---|---|---|
| A*, A, C | 136 | No (C is below B) |
| A, A, B | 136 | Yes |
| A*, B, B | 136 | No (needs two As) |
| A*, A*, C | 144 | No (C is below B) |
Same tariff total does not mean the same offer is met. Check the specific grades required.
A-Level Results 2025: The Numbers
The 2025 A-Level results confirmed that grading has fully returned to pre-pandemic standards. Here are the headline figures:
| Measure | 2025 | 2024 | Change |
|---|---|---|---|
| Pass rate (A* to E) | 97.4% | 97.1% | +0.3% |
| A*/A rate | 28.2% | 27.6% | +0.6% |
| A* to C rate | 77.7% | 76.0% | +1.7% |
| Students with three A*s | 4,043 | Not published | N/A |

The modest increases from 2024 to 2025 represent normal year-on-year variation, not a return to grade inflation. The overall A*/A rate of 28.2% is broadly in line with 2019 (pre-pandemic) levels, confirming that Ofqual's correction is complete. One notable statistic: boys achieved more A* grades than girls (9.8% vs 9.1%), though girls continued to outperform overall at A*/A combined.
The Covid Years and Grade Inflation
If your child has an older sibling who received A-Level results between 2020 and 2022, you may have noticed their grades looked unusually high. That is because they were. Understanding this context matters, because some parents compare the two and worry that standards have risen when in reality the earlier grades were inflated.
Why 2020 to 2022 Results Are Not Comparable
In 2020, A-Level exams were cancelled entirely. Grades were initially determined by an algorithm, which caused widespread outrage when it downgraded students from disadvantaged areas. The government reversed course and used centre-assessed grades (teacher predictions) instead. The A*/A rate jumped to 38.5%, up from 25.5% in 2019.
In 2021, exams were cancelled again. Teacher-assessed grades pushed the A*/A rate even higher to 44.8%. In 2022, exams returned but with “generous” grading as a transition measure, producing a 36.4% A*/A rate. Only from 2023 onwards did Ofqual fully return to pre-pandemic standards, with a 27.2% A*/A rate that year.
A grade A from 2021 is not the same standard as a grade A from 2025. If your older child received all As during 2020 or 2021 and your younger child is getting Bs in their mocks, that does not necessarily mean they are performing worse. The grading systems were fundamentally different.
What Parents Should Focus On
After all this detail, the practical takeaway is surprisingly simple: grade boundaries are out of your control. They are set after the fact by people your child will never meet, using a process that depends on how every other student in the country performed. Spending time trying to predict boundaries is time taken away from the things that actually improve results.
The parents I worked with who had the calmest experience of A-Level year all had one thing in common: they focused on the process rather than the outcome. They asked their children, “Have you done a timed paper this week?” rather than “What grade do you think you'll get?” That shift in language makes a bigger difference than most people realise.
Prioritise past papers with mark schemes
Mark schemes show exactly what examiners are looking for. A student who has worked through five years of past papers knows the exam format inside out and can focus marks on the questions where they are most available.
Check the specification, not just the textbook
The exam board specification lists every topic that can be examined. If your child is using a textbook, make sure it matches their specific board (AQA, Edexcel, OCR). Tutorioo’s AI tutoring follows the exact specification for each board, so nothing is missed or studied unnecessarily.
Do not set fixed percentage targets
Telling your child they need 75% for an A can create unnecessary anxiety, especially when the actual boundary might be 68% or 82%. Instead, focus on improving marks on each paper they practise. Progress across papers is what matters.
Understand the remark process before results day
If your child is one or two marks below a grade boundary, the school can request a review of marking. Know how this works before August so you can make a calm decision on the day rather than panicking.
Every exam board publishes its A-Level specification for free online. It is the definitive list of everything that can appear on the exam. If your child has not read their specification, they are revising blind. Sit down with them and go through it together. Tutorioo's A-Level tutoring is built around these specifications, covering every topic your child needs.
On Results Day
A-Level results day is the third Thursday of August. In 2026, that is expected to be 13 August. Results are released to schools in the early morning, and students collect them in person or access them online (depending on the school). UCAS Track updates throughout the morning, showing whether university offers have been confirmed.
If results are not what was expected, do not panic. Clearing opens on results day, and universities actively recruit through Clearing for courses that still have places. Your child's school will have advisers available to help navigate next steps.
Requesting a Remark
If your child is close to a grade boundary, the school can request a review of marking (often called a remark). There are two types:
Priority Review
- •For students holding a university place that depends on the grade
- •Completed before the UCAS deadline for confirmation
- •Costs vary by board (typically around £40 to £50 per paper)
- •Must be requested through the school, not by parents directly
Standard Review
- •For all other remark requests
- •Takes several weeks to complete
- •Same cost range as priority
- •Grade can go up, stay the same, or go down
This is important: a remark is not a free second chance. The new mark replaces the original, and it can be lower. The school can request a copy of the marked script first, which lets your child see exactly where marks were awarded and whether a remark is likely to help. Always do this before requesting a review.
A-Level grade boundaries can feel opaque, but once you understand the system, it becomes clear that the process is designed to be fair. The boundaries exist to protect your child: to ensure that a tough paper does not unfairly punish them and that an easier paper does not hand out unearned grades. Your job as a parent is to support consistent, specification-led revision, and to trust that the system will do the rest.
If your child needs structured support that follows their exact exam board specification, Tutorioo's AI A-Level tutoring adapts to their board, tracks progress across topics, and is available whenever they need it. It is free to try, and there is no booking or scheduling required.
