GCSEs in England are graded on a 9-1 numeric scale, with 9 the highest and 1 the lowest, replacing the old A-G letters. Grade 4 counts as a "standard pass" and grade 5 as a "strong pass" — the two thresholds you'll see referenced most often by schools.*

If your own GCSEs (or O-levels) were graded in letters, the 9-1 scale can feel like it arrived from nowhere. It didn't — it was phased in deliberately, subject by subject, starting in 2017. Here's what it actually means and how to read a report that uses it.

How the 9-1 scale works

The scale runs from 9 (highest) down to 1 (lowest), with a "U" (ungraded) below that for work that doesn't meet the standard for grade 1. It was introduced in England from 2017, starting with English Language, English Literature and Maths, and rolled out to most other GCSE subjects by 2019.

Two grades matter more than the rest for practical purposes:

  • Grade 4 — "standard pass". This is the level most commonly used as the pass/fail line in conversation, league tables and post-16 requirements.
  • Grade 5 — "strong pass". A higher bar, increasingly used by sixth forms and some employers as their effective entry requirement, particularly for competitive courses.

How it compares to the old A*-G scale

The two scales don't map onto each other point-for-point — that's a common misconception. The numeric scale was deliberately built with more grades at the top than the old system had, to spread out the highest-achieving students more clearly.

Old grade Roughly maps to
A* 8 or 9
A 7
B 5 or 6
C 4 or 5
D 3
E 2
F/G 1

Treat this table as a rough guide, not a formula — grade boundaries are set separately each year by each exam board for each subject, based on how the whole cohort performed, so the same raw mark can land in a different numeric grade from one year to the next.

Why grade 9 is different from the old A*

Grade 9 was designed to be harder to achieve than the old A* — a smaller proportion of students nationally are awarded a 9 in any given subject than used to be awarded an A*. The idea was to give universities, employers and sixth forms a clearer way to distinguish the very highest performers from students who are merely very good.

What "pass" actually means in practice

There's no single official GCSE "pass mark" in the way many parents expect — it depends what the grade is being used for:

  • For general reporting and government statistics, grade 4 and above is usually the headline "pass" figure.
  • For post-16 progression in England, students who don't achieve grade 4 in English and Maths are generally required to keep resitting or working towards it alongside their next stage of study.
  • For sixth form and college entry, individual institutions set their own requirements — often grade 5 or above in relevant subjects for A-level entry, sometimes grade 6 or 7 for the most competitive subjects or schools. See our guide on GCSE grades and sixth form entry requirements for more detail.

A note on other UK nations

This 9-1 numeric system applies to GCSEs sat in England. Wales retained the A*-G letter scale for GCSEs set by WJEC, and Northern Ireland's CCEA board uses its own approach, including an extra A* and C* at certain points. If your child is sitting exams outside England, it's worth checking directly with their school which scale applies.

How this connects to the rest of the picture

Grading is one piece of a bigger picture that includes predicted grades, what actually happens on results day, and what the options are if a resit is needed. If your child is sitting iGCSEs rather than GCSEs, the grading picture is a little different — see GCSE vs iGCSE: what's the difference for how the two scales compare.

FAQ

What grade is a "pass" at GCSE?

Grade 4 is generally referred to as a "standard pass" and grade 5 as a "strong pass". Grade 4 is the threshold most commonly used for progression purposes — for example, students in England who don't achieve at least a grade 4 in English and Maths are usually required to keep studying towards it post-16.

What is grade 9 equivalent to in old money?

Grade 9 sits at the very top of the scale, above where the old A* used to sit — it's designed to be a narrower, more stretching top grade than A* was, so fewer students achieve a 9 than used to achieve an A*.

Why did GCSEs move away from A*-G?

The numeric scale was introduced from 2017 alongside a wider reform of GCSE content and assessment in England, partly to create a clearer distinction between top-performing students (via the new grade 9) and to signal that the new-style GCSEs were more demanding than the qualifications they replaced.
