GCSE: is it true they're graded so that ca 1/3 must fail? How are boundaries decided?

I understand that grade boundaries can change from year to year and from exam board to exam board. E.g. a 4 in Maths can be 40 points out of 240 one year and 45 out of 240 another year. That I get.

What I don't understand is:

  • what, exactly, is the statistical methodology to adjust the boundaries from year to year? Is it even publicly disclosed? How much of a subjective, qualitative assessment is it?
  • Is it true that the exams are graded on a curve in such a way that, by design, ca. 1/3 of the kids will fail?

On the last point, there are many mumsnetters who hold very strong opinions that it's true, but I have not found official confirmation.

If it were true, it would mean that the bottom third would fail regardless of score; e.g. one year the bottom third could score 40% of the points, another year 55%.

If we look at Maths Grade boundaries for Edexcel, we see that a 4 has ranged from 51% to 60% of the total points in the foundation paper, and from 17% to 22% of the higher paper. These are not percentiles, but percentages of the total point. https://mathsbot.com/gcse/boundaries

This doesn't seem to me like a system that's designed to fail 1/3 of the students regardless of score.
If you get less than 50-60% of the questions right in the easier version of the exam, and less than 20% in the harder version, it seems pretty clear to me that you have not even mastered the basics of the subjects. In many countries 60% or thereabout tends to be the threshold for passing.

This is also why I don't understand those who say that 1 to 3 are also passes. You pass if you get 10% of the points? What is the definition of failing then?

Or am I missing something?

TES explained that in the first year the % of grade 9 was set equal to a certain % of those achieving >=7, but how it changed after the first year is unclear https://www.tes.com/magazine/analysis/secondary/gcse-and-a-level-grade-boundaries

@Bobbybobbins But then set that rates of 4+ are norm referenced.

Why do you say they are? They are not. That's the myth that refuses to die.
As per previous links and quotes above, the Ofqual chief has clarified this very explicitly: what you say is not true.

@sashh No allowance is made for whether you only arrived in the country last year or that you have been in hospital for a month or 100 other reasons you might underperform.

Sure, but how many such cases are there? How much of the 30-40% fail rate do they account for? It's already been pointed out that there is much more attention on special needs and neurodivergence, with kids given extra allowances if warranted.

Also, English as a second language can mean very different things. It can mean children of humble, ignorant immigrants who have just arrived in the country and are not very literate, but it can also mean bilingual or trilingual children of highly successful and educated foreign professionals. E.g. in many London schools, kids with English as a second language outperform the others.

What frustrates me the most (20+ years secondary teaching) is when the govt says they want to increase pass rates. But then set that rates of 4+ are norm referenced. Before this, rates did steadily increase but then there were annual complaints about grade inflation.

sashh · 13/09/2025 11:46

To think that 30 to 40% of our country's kids fail that is shocking.

Not really. These days all children sit GCSEs when they are 15/16. There is bound to be a difference in achievement.

No allowance is made for whether you only arrived in the country last year or that you have been in hospital for a month or 100 other reasons you might underperform.

IMHO some children should not be put in for GCSEs or should sit a smaller number of subjects with more teaching.

But I don't make the policy.

Araminta1003 · 13/09/2025 11:32

@ParentOfOne - I am not being nasty or aggressive. I am just pointing out that you are a hypocrite. Ranting on one thread about church schools and tangentially about grammar schools, and on another thread, admitting that you are putting your own DC forward for the Wandsworth Test which is an 11 plus test.
People on MN tend to panic about the education system when they are going through the 11 plus, KS2 SATS, GCSEs, A level and clearing. But quite often it is people who have high achieving kids who are going to be fine one way or another. So the whole thing comes across as disingenuous.

This thread has explained clearly that a 3 is not a “fail” and the history surrounding O levels. Leave it at that.

And in real life I have plenty of friends who are extremely high achieving academically including in Maths, who have failed to do proper and savvy financial long term planning. So I am not convinced top grades go hand in hand with being financially savvy or investment savvy whatsoever.

Snorlaxo · 13/09/2025 10:33

I supposed I would have hoped that, since kids mature and develop at different paces, maybe it's less surprising for some kids to do less well when they are 10-11 than when they are 15-16

Some kids do better than expected at GCSE based on their KS2 SATS but others don’t follow their expected trajectory because adolescence and life stuff.

@noblegiraffe ,

I have not looked at where the grade boundaries come in in Maths recently. But under 20% say should probably be a U.

The reality is that we should have a Maths competency certificate where people are taught life skills, and those neither good or interested in mathematics take that. There is no point in teaching or examining trigonometry or algebraic equations to those struggling with basic arithmetic and logic.

It is cruel to the pupils. I have taught physics to students who just try to learn the words. Neither of us get anything out of the experience!

20% would get you a mid grade 1 currently. So not that far off what you are expecting.

Agree that maths GCSE is not fit for purpose at the lower end, but suggesting that anything below a grade 4 is a fail is ignoring how the GCSE actually works. It's not a fail, it's a level 1 pass. It replaces CSE maths. Grade 4 and above replaces O-level maths.

If you want those who get below a grade 4 to sit a different exam instead, then we're back to O-levels and CSEs.

TeenToTwenties · 13/09/2025 10:23

Your O levels were 3hrs? Mine weren't. Anyway O levels were aimed at the top 20% or so. GCSEs are meant to be suitable for all.

My degree maths papers were 3hrs each. (4 papers over 2 consecutive days.)

Fearfulsaints · 13/09/2025 10:19

The issue with saying someine is bad at maths, and I agree it probably isn't someone's strong point, is we need exams to demonstrate what people can do. They are used as a gateway to next steps and employment.

Pupils who are not at a level of a 4, can generally still do some useful maths and they need to demonstrate this.

I have one son who has SEN and he sat Level 1 functional skills. Its still employment worthy maths. He can add, follow a recipe and adjust it etc.

noblegiraffe · 13/09/2025 10:19

@Newbutoldfather so your preference would be that anything below a 4 simply got awarded a U?

Newbutoldfather · 13/09/2025 10:16

@TeenToTwenties ,

I am afraid it really does!

Exams have reduced in length dramatically over the years. My O levels were 3 hours. Also, special needs now get access arrangements, so someone lacking stamina would get rest breaks.

If you get a 3, you are bad at Maths (or English). I could say that you have attained badly but might have great potential, but I would be lying! That might explain a 5 or a 6, but a 3, no.

(Of course, there are rare exceptions to what I have written, but they really are vanishingly rare)

Not everyone can be good at every everything and obfuscation doesn’t change this. Sometimes it is better to admit that something isn’t for you and find something that is.

CosyMintFish · 13/09/2025 10:07

@ParentOfOne Ofqual have a statutory role (lots of info on their website)

Following concerns that grade rises in the UK from 1980s to 2000s was a result of inflation rather than improvement in standards, some analysis was done which showed that literacy rates hadn’t improved in line with increased grades.

The conservative government’s education reforms from 2010 onwards introduced a more rigorous role for Ofqual in ensuring that the benchmarks and expectations for UK secondary education were in line with the best overseas education systems, and that there was consistency of standards year on year. There are tests given to Y11 students independently of GSCEs to check whether standards are improving or not and which help set grade boundaries to ensure consistency between cohorts in different year groups.

It is not the case that a quarter must fail, or any particular criterion like that. If you look at any comprehensive cohort, the progress 8 score demonstrates that it’s certainly not the case that a particular proportion will fail - it’s down to the teaching as well as the ability and motivation of the child.

TeenToTwenties · 13/09/2025 10:04

@Newbutoldfather If someone gets a 3 it doesn't mean they are 'really bad' at maths or English.
It can just mean for example they don't have the stamina for the exams or confidence to have a go or linguistics to interpret.

Newbutoldfather · 13/09/2025 09:59

I think people will always know where a pass and fail is, however you dress it up.

If someone gets a 3 or under in maths, they are really bad at maths! And if you change the nomenclature or grading system, people will still know what is good and what is bad.

Some competition and stress is a healthy thing and there do have to be winners and losers. In the animal kingdom the consequences of failing at running or fighting can be death or banishments. I think we can live with a low grade on a certificate.

The main positive change in education in the last 50 years is the recognition of process over outcome and the praise for effort and improvement.

But we will never (and nor should we) not recognise success of outcome and that comes with the corollary of failure.

noblegiraffe · 13/09/2025 09:00

Before GCSEs we had O-levels and CSEs. O-levels represent the 'level 2 pass' grades, and CSEs the 'level 1 pass' grades.

No one, in the olden days, said that passing a CSE was 'failing an O-level'.

Which is why it is entirely correct to say that a level 1 pass is a pass. It's not a 'level 2 fail'.

Fearfulsaints · 13/09/2025 08:56

The point of a level 1 pass, is in some circumstances it can let you progress to a level 2 course.

So with maths and English you are going to continue your studies anyway as we decided everyone needs a level 2 pass to function in society (although thsts clearly not true, plenty of people work having failed to achieve level 2)

But a lot of level 2 courses at sixth form colleges will set and entry requirement of 4 level 1 qualifications.

@Talipesmum I ask because I want to understand how GCSEs work, and how to interpret school stats when I see schools where half the kids cannot get a 4 in English and maths. I didn't know the % of kids failing to get a 4 in English and Maths ranged from 30 to 40% depending on the year, I find it shocking.

GCSE is not advanced calculus that only scientists will need and apply. It's life skills. People who fail to get a GCSE 4 are unlikely to understand how their mortgage works, or how to convert the doses of a recipe for 6 people if they want to cook for 4. To think that 30 to 40% of our country's kids fail that is shocking.

@BreakingBroken I don't think Canada has a % that fail just to satisfy a bell curve.
But neither does the UK, despite many people thinking just that

@Talipesmum that’s not because exam boards say “cut off the bottom 30%”
But that's exactly what many people think. There are many posts of angry mumsnetters very convinced of exactly this

@TheLivelyViper A GCSE is a level 2 qualification, anything below a 4 is a fail on the level 2. However a 1-3 grade is a level one qualification but obviously shows a lack of grasp of the basics of a subject but nonetheless is a level qualification you can use to perhaps get onto a level 2 at college etc

This much wasn't clear to me, so thanks for clarifying. Obtaining a 1 can mean getting something like 10-15% of the total marks.

Yes a 1 is a very low grade, and obviously means a lot of the content is misunderstood as would the skills needed to write the essays or show working for a question etc. Many people if they score below a 4 for, for Maths and English will resit the exam. Obviously even for some part-time jobs etc they still want a number of grades at 4 or 5, so it can be a barrier to that, but can allow for them to get onto a Level 2 college course.

It is sort of built into every exam system, that some people won't have the knowledge or skill to meet x grade. A grade 4 has certain requirements across the board, and it makes sense that not everyone each year will meet that barrier. The levels you could say are too high as this year the amount that passed both Maths and English dropped a little more but it's around 67% I think, so you could say that having around 30% of people is too many but again as someone else mentioned it aligns with KS2 results.

ParentOfOne · 13/09/2025 08:50

@Leftrightmiddle They wouldn't be forcing those of whom exams don't work to sit exams they know they will fail. They would teach them in a way that they can learn.

I think the UK already does it better than other countries, because it doesn't force all kids to do the same maths exam, and it does differentiate between a foundation and a higher paper.

Where maybe we may disagree is that I think a 4 in GCSE maths is basic life skills that are useful in life regardless of your profession; as per the examples above, it's things like working out percentages, fractions, converting from metres to cms, rescaling the dose for a 4-people recipe to 6 people, etc.

We have so many children with SEN not even having a appropriate environment. So many unable to even attend school. And these won't even show up on the data as they aren't doing exams.
Capable of learning if only they had the chance

That's very true. It's also the dark side of having so much focus on exams and results, and giving schools (especially secondary academies) so much autonomy that they are practically unaccountable to anyone: they have an incentive to game the system, to create an environment which is hostile to special needs children and to anyone who'll lower their averages, etc.

It is also a testament to how unequal and fractured our society is, and how many kids sadly live in broken homes (I don't mean divorced parents but dysfunctional, sometimes outright dangerous family environments).

At the end of the day, many schools have improved massively when the area gentrified. Even the best teachers and headteachers cannot do miracles.

@Araminta1003 Only 62% passed all elements of KS2 SATs. So hardly a surprise that of the remaining 38% plenty won’t pass both Maths and English language GCSEs.
Not sure why the GCSE statistics would come as a surprise?

Good point. I hadn't looked into KS2 SATs but, sure, with that in mind, the results are hardly surprising.
I supposed I would have hoped that, since kids mature and develop at different paces, maybe it's less surprising for some kids to do less well when they are 10-11 than when they are 15-16

@Araminta1003
Do you have a problem with the KS2 statistics too and how it is done there?
Perhaps focus on the link between KS2 and GCSE and stop panicking about the entire education and political system.

Yes, we have had strong disagreements on some topics, but why be so nasty and aggressive? Why come at me like this for what I still dare consider is a perfectly legitimate question? If someone you hadn't disagreed with had asked a similar question, would you have reacted the same way? If I trigger you so much, please just ignore me.

@JamesWebbSpaceTelescope Please stop saying a level 1 qualification is a fail.

Come on, that is just semantics.
Depending on the year and the exam board, failing to get a 4 in Maths means something like scoring < 15-20% on the higher paper or less than 50-40% on the foundation one https://mathsbot.com/gcse/boundaries.

Do you want me to rephrase that this country considers scoring < 15-20% "technically not a fail but a level 1 pass" (while pretty much everywhere else in the world that would be a very bad fail)? Sure, let's clarify that, let's split that hair. What changes in practice? A "level 1 pass" remains not sufficient, kids achieving that still need to retake their GCSE, it still signals a terrible understanding of the subject.

A "true fail" would be what? Scoring 5%? Even answering completely at random, it is probably easier to get a "level 1 pass" than a fail.

@MigGirl The maths is actually quite high brow. It doesn't mean those who get lover grades wouldn't be able to understand basic life skill maths. Life skills maths have very little input in the GCSE

I disagree.
I agree that getting the very very top grades in some past papers may have been hard.
I do not agree that getting a 4 is.
As above, a 4 means something like 15-20% on the higher paper or 40-50% on the foundation one.

Foundation papers have questions like:

work out 120 - 89
simply 3xax4
convert litres to millilitres
If you need 200g of sugar for 20 cookies, how much sugar do you need for 60 cookies?
basic percentages
etc

Your language is incorrect.

Grades 1-3 are a level 1 pass. This is not a fail!
Grades 4-9 are a level 2 pass.
Alevels (some Btecs, T- levels etc) are level 3
HNC - level 4
HNC - level 5
Honours degree - level 6
Masters degree - level 7
PhD - level 8

Not all students at 16 reach the standard for a level 2 qualification. There are then options to support them gain level 2s via different routes, BTECs, resits, apprentiships, which can suit some more than sitting in a classroom. It is not uncommon for them to go on and gain higher level qualifications after that.

Please stop saying a level 1 qualification is a fail.

On the other thread you said your DC is academic and higher attaining. Should your DC achieve Greater Depth at KS2 across all subjects, the secondary they end up at - their own trajectory will be fine! Perhaps focus on the link between KS2 and GCSE and stop panicking about the entire education and political system.

Schools aren't fit for purpose. We are putting children into exams we know a percentage will fail.
However, that %is decided isn't really relevant..every year a % fail. I can't see a situation where they all pass because IF that happened the bar would be raised.
It's a system to scare some of the population to revise that bit harder so they aren't one of the failures.
It's a system that if every one got As and decided to be accountants then society won't work we need people to do every type of job. What we should be doing in valuing the variety of skill and aptitudes. Understand that all people are important and not dismiss some work as less than others. But currently we do. Who heard in school if you don't work hard your have to work in a shop or pick up rubbish? And yet where would society be without people doing this work?

But most importantly if the powers of be actually wanted to get the best skills and knowledge and development out of young people they would make sure education worked for all. They wouldn't be forcing those of whom exams don't work to sit exams they know they will fail. They would teach them in a way that they can learn.

We have so many children with SEN not even having a appropriate environment. So many unable to even attend school. And these won't even show up on the data as they aren't doing exams.

A star grade*

Previious post bolded it instead of adding the star

Newbutoldfather · 13/09/2025 07:13

I don’t know the answer to this and I taught for years!

I know it isn’t keeping the percentages at each grade the same. Many many years ago (when I sat my O levels!) this was the case. But then they lifted this requirement in order to take ‘progress in teaching’ into account and the great grade inflation started.

The most egregious example of this is uni grades where a 2/1 means nothing these days but fully 20% of grades used to be thirds in the 1980s.

The other thing to remember is that examination boards are competitive profit making organisations and compete with one another to get students to sit the paper. One example I know of is that when the new A A level grade was introduced, boards were told to make it ‘rare’. In Physics, most boards kept this at 5-6%. AQA shamelessly went for a full 12% being awarded A, and consequently many schools shifted to AQA. I think the boards have gradually equalised this now.

So, it is an amorphous process which the boards will claim is in some way objective, but I doubt really is. They need to maintain credibility with the unis at the same time as pushing themselves as best for the pupils.

And now they are under pressure from the government to keep GCSEs more rigorous and not award too many top grades.
