GCSE maths grades 1 to 9: what each grade means

The short answer. GCSE maths is graded 9 to 1, with 9 the highest and U for ungraded. The bottom of grade 4 lines up with the bottom of an old C, and the Department for Education treats grade 4 as a standard pass. Students below grade 4 in maths keep studying it after 16. Grade boundaries are reset every year after marking.

The scale

How 9 to 1 compares with the old A* to G.

GCSEs in England have been graded on a 9 to 1 scale since 2017, replacing the old A* to G letters. Grade 9 is the highest, grade 1 the lowest, and U means ungraded.

Ofqual is clear that the number scale is not a straight swap for the letters. The two scales only line up at three anchor points: the bottom of grade 7 matches the bottom of an old A, the bottom of grade 4 matches the bottom of an old C, and the bottom of grade 1 matches the bottom of an old G.

So an employer or college that used to ask for a C now normally asks for a 4.

Grades 4 and 5

Why grade 4 in maths matters more than any other line.

Grade 4: the standard pass

The Department for Education recognises grade 4 and above as a "standard pass" in all subjects. In maths and English it is also a threshold: a student without a grade 4 in maths by 16 keeps studying maths as part of their post-16 education.

Full-time students with a grade 3 must work towards the GCSE again. Students with a grade 2 or below can study towards Functional Skills Level 2 or the GCSE. Our resit guide sets out the rules.

Grade 5: the top of Foundation

Grade 5 is the highest grade available on Foundation tier and one of the two grades, with 4, that can be earned on either tier. Colleges, sixth forms and employers set the grades they require, so check the exact maths requirement with the place your child is applying to.

For a student whose honest target is a 5, Foundation often lets every mark count towards it. Our Foundation vs Higher guide explains the trade-off.

Grade bandWhich tierWhat it usually means in practice
7, 8, 9Higher onlyReachable only on Higher papers, which include the Higher-only content such as the quadratic formula and the sine and cosine rules
6Higher onlyAbove the Foundation ceiling, so it can only be reached on Higher papers
4 and 5Either tierGrade 4 is the standard pass and the post-16 maths threshold
3Foundation, or an allowed grade 3 on HigherBelow the threshold; full-time post-16 students resit the GCSE

Grade boundaries

Boundaries move every year, and that is the point.

A grade boundary is the lowest total mark that earns a grade. Exam boards set them after the exams are sat, when marking is nearly complete, because nobody can know in advance how hard students will find a new paper.

Ofqual describes the process in two steps. First, data about this year's students is compared with previous years to find likely boundaries. Then senior examiners read real scripts on and around those marks and compare them with scripts at the same grades the year before. If a paper turned out easier, the boundaries go up; if harder, they come down.

Ofqual is also clear that "there are no quotas" for how many students pass, and no cap on how many get each grade.

Marking

Scripts are split by question and marked anonymously to a mark scheme.

Data

Results are compared with previous cohorts to find likely boundaries.

Examiner review

Senior examiners read scripts at those marks against last year's work.

Grades issued

Final boundaries are applied to every student's total mark.

In GCSE maths there is an extra check. Every February and March, students at more than 300 schools in England sit the National Reference Test, which helps Ofqual see whether maths performance nationally is really rising or falling.

Use the numbers well

How to read a mock result without fooling yourself.

One student, three papers

Maya sits three 80-mark papers and scores 41, 52 and 47. What is her total and percentage?

Total = 41 + 52 + 47 = 140 out of 240
140 ÷ 240 = 0.583... ≈ 58%

The grade comes from the total across all three papers, so her weakest paper still pulls her up or down. Compare that total with the boundaries for the same series and board, not with a percentage from another exam.

Where the marks went

Her 100 lost marks, sorted by a tutor:

Gaps in knowledge: 46
Method slips: 31
Ran out of time: 23

An illustration of the sorting we do, not a real student. Slips and timing are usually the fastest marks to win back, so they shape the first weeks of the plan.

How we help

A grade measured on real papers, then a plan to move it.

In the first lesson the tutor watches your child work through full questions at their tier and sorts every lost mark into a gap, a method slip or timing. You leave with the grade they are working at and the next one within reach.

Lessons then follow the plan: the topics that carry the next grade's marks, timed papers in your board's format, and mark schemes read together so method marks are not wasted. Every lesson is live, with the same tutor, after school or at weekends in UK time.

We never promise a grade or a score. Results depend on the starting point, the time available and the practice done between lessons, and we say so at the start.

Common questions

GCSE maths grades: what parents and students ask.

What is the highest grade in GCSE maths?

Grade 9. The scale runs from 9 at the top to 1, with U for ungraded.

Is grade 4 a pass in GCSE maths?

The Department for Education recognises grade 4 and above as a standard pass in all subjects. In maths it is also the line below which students keep studying maths after 16.

What is a grade 4 in old money?

Ofqual says the bottom of grade 4 is comparable to the bottom of the old grade C, so a grade C requirement is normally replaced by a grade 4.

What does grade 7 compare with?

The bottom of grade 7 is comparable to the bottom of the old grade A.

What happens if my child gets a grade 3 in maths?

Students on a full-time post-16 study programme with a grade 3 must keep studying towards the maths GCSE. Students with grade 2 or below can study towards Functional Skills Level 2 or the GCSE. See our GCSE maths resit guide.

How are GCSE maths grade boundaries set?

After the exams, exam boards compare this year's results with previous years, then senior examiners review real scripts at the likely boundary marks. Easier papers get higher boundaries and harder papers lower ones.

Are grade boundaries the same every year?

No. They change every year to reflect how hard each paper was, so the standard needed for a grade stays comparable from year to year.

Can you get a grade 6 on Foundation tier?

No. Foundation tier awards grades 1 to 5. Grades 6 to 9 are only available on Higher tier.

Is there a limit on how many students get each grade?

No. Ofqual says there are no quotas and no cap on the number of students who can get each grade.

Can you help my child move up a grade?

We can help them work towards it, though we never promise a grade. Book a Priority Demo: a full live class of about 45 to 60 minutes with a mentor reserved for your child, followed by a written skill report and a personal learning roadmap on WhatsApp.

Know the grade, then plan the next one.

Bring a recent mock. In one live class we show which grade the work supports today, where the marks are going and what the next term should look like. If you enrol, the demo fee is adjusted against your first month's fee.
