GCSE Grades Explained: 9 to 1, Grade 4 vs 5, and the Resit Rule

GCSETutors5 min read

The Short Answer

In England, GCSEs are graded from 9 (the highest) down to 1, with U for unclassified. Grade 4 is a "standard pass" and grade 5 is a "strong pass". If your child does not get at least a 4 in English and maths, they will usually have to keep studying those subjects after 16. In Wales, WJEC GCSEs still use the letter grades A* to G.

How the 9 to 1 Scale Maps to the Old Letters

England moved from letters to numbers between 2017 and 2020, subject by subject. Ofqual, the exams regulator in England, set three anchor points so the old and new scales line up:

  • The bottom of a grade 7 lines up with the bottom of an old A.
  • The bottom of a grade 4 lines up with the bottom of an old C.
  • The bottom of a grade 1 lines up with the bottom of an old G.

In practice, that gives a rough translation:

  • 9, 8, 7 cover the old A* and A.
  • 6, 5, 4 cover the old B and C.
  • 3, 2, 1 cover the old D, E, F and G.

Grade 9 is not simply a new name for A*. Ofqual designed it so fewer students get a 9 than used to get an A*. It marks the very top of the old A* range.

Grade 4 vs Grade 5: What Is the Difference?

Both count as passes. The difference matters mainly for schools and for what comes next.

  • Grade 4, the standard pass, is the level that clears the English and maths requirement after 16 (more on that below). Many employers and courses that used to ask for a C now ask for a 4.
  • Grade 5, the strong pass, is the measure the Department for Education uses in school performance tables. Some sixth forms and courses ask for a 5 rather than a 4, especially in English and maths.

So a 4 is a pass. A 5 gives more options.

What Do Sixth Forms and Colleges Ask For?

There is no national entry rule. Each sixth form and college sets its own. Common patterns are:

  • Around five GCSEs at grade 4 or above, often including English and maths, for a general sixth form place.
  • A grade 6 or 7 in a subject your child wants to take at A level, particularly maths, the sciences and languages.
  • Lower entry points for vocational courses and many college programmes, sometimes with English or maths taken alongside.

The only reliable answer is the prospectus for the places your child is considering. Look these up early in Year 11. They tell you which grades actually matter for your child, which helps you decide where extra effort or tutoring is best spent.

The Resit Rule for English and Maths (England)

In England, students aged 16 to 19 on a full-time study programme who have not got a grade 4 in English or maths must keep studying that subject. This is a condition of funding for schools and colleges, set by the Department for Education. What your child studies depends on their grade:

  • Grade 3: they must work towards the GCSE again. In practice, this means resitting.
  • Grade 2 or below: they can work towards either the GCSE or a Functional Skills qualification at level 2.

This is the single most important grade line for many families. A grade 3 in maths means another year or more of GCSE maths alongside everything else. If your child is near the 3/4 line in English or maths, that is where focused help often makes the biggest practical difference.

Resit opportunities exist. In England, students aged 16 or over can resit GCSE English language and maths in a November series as well as the summer. Your child's school or college will advise on timing.

Tiers and the Grades Available

Some subjects, including maths, the sciences and modern languages, have two tiers. Foundation tier papers cover grades 1 to 5. Higher tier papers cover grades 4 to 9, with an "allowed" grade 3 in some cases if a student narrowly misses a 4. If your child needs a 6 or above, they must sit Higher. The school decides the tier, usually during Year 11, so ask how and when.

GCSEs in Wales: A* to G

Wales did not move to numbers. GCSEs taken in Wales are mainly set by WJEC and graded A*, A, B, C, D, E, F, G, with U for unclassified. That includes the new made-for-Wales GCSEs that schools began teaching in September 2025. The first of these will be awarded in summer 2027, still on the A* to G scale.

If you are comparing results across the border, the anchor points still help. A C in Wales and a 4 in England sit at a similar level. But they are different qualifications, set by different boards to different specifications, so a direct swap is only ever approximate.

Some schools in Wales also offer a few subjects through WJEC's Eduqas board, graded 9 to 1. Your child's school can tell you which scale each of their subjects uses.

Reading a Results Slip

  • Numbers (9 to 1) mean an England-style GCSE.
  • Letters (A* to G) usually mean a Welsh GCSE, or an older qualification.
  • Double grades such as 6-5 come from combined science, which is worth two GCSEs.
  • U means the work did not reach grade 1 or G.

The Bottom Line

Know which line matters for your child. For most families it is the grade 4 in English and maths, because missing it means more study after 16. Beyond that, check the entry grades for the sixth forms or colleges your child likes, and aim for those. If your child is close to a key line in maths, a GCSE maths tutor working on their specific gaps can be a sensible use of a few months.
