What a Grade C Is in the New GCSE System

A grade 4. The bottom of 4 was aligned with the bottom of the old C — but grade 5 is the government's "strong pass", which is why two answers circulate.

Réponse courte

What is a grade C in the new GCSE numbers?

A grade 4. Ofqual aligned the bottom of grade 4 with the bottom of the old grade C, and told institutions that a former C requirement should become a grade 4 requirement.

La réponse en bref
A grade C corresponds to a grade 4. Ofqual aligned the bottom of grade 4 with the bottom of the old grade C and stated that an entry requirement previously set at grade C should now be set at grade 4. Grade 5 also sits inside the old C and B territory, which is where the confusion starts.

Ce qui change la réponse

If an institution wrote its requirement before 2017 and never revised it, "C or above" means grade 4 and above.
If an institution has revised it since, many have chosen grade 5, which is a higher bar than the old C rather than a translation of it.
School performance measures report both grade 4 and grade 5 thresholds, so a school's internal target may be a 5 while the qualification's pass line is a 4.
For post-16 funding in England the number that matters is 4, regardless of what any individual college prefers.

Where the old C actually sits

The alignment is a single point, not a band: the bottom of grade 4 is comparable to the bottom of the old grade C. Ofqual went further and gave institutions the instruction that follows from it — if they previously set entry requirements of at least a grade C, the equivalent now is to require at least a grade 4.

The design was checked against outcomes as well as standards. Awarding in the first reformed year was set so that broadly the same proportion of students achieved grade 4 and above as had previously achieved grade C and above. The line was moved onto a new scale; it was not raised.

Why two different answers are in circulation

The Department for Education named grade 4 a standard pass and grade 5 a strong pass, and reports both in school performance tables. Schools are therefore measured twice, once at each line, and a head of department who talks about "getting the students over the line" is often talking about 5.

That is a school accountability measure leaking into public language. It is not a statement about what a C was worth. A grade 5 is above the old C boundary, not level with it, and treating 5 as the translation of C quietly raises the requirement for everyone who reads it.

Working out which number a particular requirement means

Read the requirement as it is written and note when it was written. "Grade C or above" on an old job description means grade 4. "Grade 5 or above" on a sixth form's admissions page means grade 5, and it means it because they chose it, not because 5 is what a C became.

Where a document uses both — "C/4" is common — it is telling you the requirement was translated at the anchor point and grade 4 satisfies it. Where a document says "C/5", somebody has translated it wrongly, and it is worth asking before you assume the higher bar.

The place where grade 4 has legal force

In England, a student who reaches the end of Year 11 without grade 4 in maths must continue studying maths as a condition of their post-16 funding. The rule is written at 4, not at 5, which makes 4 the only number in this discussion that changes what a sixteen-year-old is obliged to do.

For families weighing a resit, that is the practical frame. A student sitting at grade 3 is deciding whether to spend the next two years in a compulsory maths class. A student sitting at 4 who wants a 5 is making an optional choice about which doors open more easily, and the two situations deserve different amounts of urgency.

Questions fréquentes

Is a grade 4 a pass?

Yes, in the sense that matters: it is the government's standard pass and the translation of the old grade C. It is also the line written into post-16 funding rules in England. What it is not is a guarantee that every sixth form or employer will accept it, because those bodies set their own thresholds.

Is a grade 5 a C or a B?

Neither, cleanly. Grades 6, 5 and 4 together replace B and C, so a 5 falls between the two old letters with no exact match. Describing it as a high C or a low B is a fair everyday summary, but it is a description rather than an equivalence.

My employer's form asks for "C or above" — does my 4 count?

Yes. Ofqual's guidance to institutions was that a former grade C requirement becomes a grade 4 requirement, and most old wording has simply never been updated. If the form gives you a free-text box, write "grade 4 (equivalent to grade C)" and cite the year of the certificate.

Should my child resit to turn a 4 into a 5?

Only if a named destination requires it. A resit costs a term of attention that could go to A level subjects, and a 4 already satisfies the funding rule and most general entry requirements. If a specific course asks for 5 in maths, that is a reason. "To be safe" is usually not.
