What Percentage Is a Grade 4 in GCSE?

Grade 4 is the standard pass at GCSE, so it is no surprise that students and parents want to know what score it needs. Is it 40%? 50%? The real answer is more interesting, and it can actually make you feel a lot better about your child's chances. Let us look at it in plain English.

What Does Grade 4 Mean at GCSE?

GCSEs in England are graded from 9 to 1, with 9 the highest. A grade 4 is called the standard pass, and a grade 5 is the strong pass. A grade 4 is roughly equal to a low grade C in the old system. This matters because many colleges, sixth forms and employers ask for a grade 4 in English and Maths. We explain more in our guide on whether a grade 4 is a pass at GCSE.

Why Is There No Fixed Percentage for a Grade 4?

GCSE grades are not given by a fixed percentage like a school test. Instead, each exam board sets a grade boundary, which is the lowest mark needed for each grade. They set it after the exams are marked, so that a grade means the same standard every year, even when one paper is harder than another.

That is why a "40% is a pass" rule does not work. The real percentage depends on the paper. You can read the full process in our guide on how GCSE grade boundaries are decided.

What Percentage Did a Grade 4 Need in 2026?

Here is a real example. These are the 2026 GCSE Maths grade 4 boundaries from four exam boards, turned into percentages by Third Space Learning. They use the marks needed divided by the total marks.

Exam board	Tier	Grade 4 mark	Percentage
Edexcel	Higher	50 out of 240	20.8%
Edexcel	Foundation	151 out of 240	62.9%
AQA	Higher	63 out of 240	26.3%
AQA	Foundation	154 out of 240	64.2%
OCR	Higher	57 out of 300	19.0%
OCR	Foundation	133 out of 300	44.3%
WJEC Eduqas	Higher	28 out of 240	11.7%
WJEC Eduqas	Foundation	121 out of 240	50.4%

The pattern is clear. A grade 4 needed anywhere from about 12% to 64%, depending on the board and tier. No single number fits them all.

Why Is a Grade 4 So Different on Higher and Foundation?

Higher tier papers cover grades 4 to 9 (with 3 allowed as a safety net), so they include very hard questions. Many students find these tough, so the mark needed for a grade 4 is low. Foundation tier papers cover grades 1 to 5, so the questions are easier and the mark needed for a grade 4 is much higher.

This does not mean a Higher grade 4 is easier. A grade 4 means the same standard on both tiers. It is just earned in a different way. If you are not sure which tier is right for you, read our guide on the difference between Higher and Foundation.

What About Other Subjects Like English and Science?

The same rule applies. There is no fixed percentage for a grade 4 in English, Science, History or any other subject. Each exam board publishes the exact boundaries for every paper, usually on results day. Because English and other essay style subjects are marked differently from Maths, you cannot use the Maths numbers as a guide. The safest plan is to check the boundaries for your own board, subject and tier.

Should You Aim for Exactly the Grade 4 Boundary?

No. The boundary is not known until after the exam, so you cannot plan around it. If you aim for the exact mark, one small slip can push you down a grade. A safer plan is to aim for several marks above the grade you need. Our post on whether grade boundaries are lower this year shows how boundaries move from year to year.

How Can You Make Sure You Reach a Grade 4?

1. Know where you are now. A GCSE mock exam shows how close you are and which topics need work.

2. Practise real papers. Use our GCSE past papers and mark them with the mark scheme.

3. Grab the easy marks first. Early questions are usually the most straightforward, so do not lose marks there.

4. Show your working. You can earn method marks even if the final answer is wrong.

5. Fix weak topics early. A few extra marks on each paper can be the difference. Our GCSE tutors teach one to one and focus on what you find hard.

6. Follow a plan. Our GCSE revision courses cover the full syllabus in a clear order.

Conclusion

So, what percentage is a grade 4 in GCSE? It depends. In 2026 GCSE Maths it ranged from about 12% on one Higher paper to about 64% on one Foundation paper. There is no magic number, because boundaries move each year to keep grades fair. The best plan is to practise often, check your mistakes and aim comfortably above the grade you need.
