Understanding a GCSE result is not always as simple as looking at the number or letter. England grades GCSEs from 9 to 1, with 9 the highest and U meaning ungraded. Grade 4 is commonly called a standard pass, while grade 5 is often called a strong pass. Wales uses A* to G, learners in Northern Ireland may receive letter or number grades depending on the awarding body, and Scotland follows a separate National Qualifications system.
This guide takes you through what the grades mean, how the current scale compares with old A*–G grades and why grade boundaries change. It also explains the UK differences and what a particular result could mean for further study or work.

England has used the 9–1 scale since 2017, replacing the former A*–G system. The numbered scale gives more distinction at the top: grades 7, 8 and 9 cover the part of the old scale represented by A and A*. However, the two scales are not direct one-to-one matches. Ofqual’s grade-scale guide also explains the official comparison points.
GCSE grades 9 to 4 are Level 2 qualifications, while grades 3 to 1 are Level 1. A qualification level shows difficulty, but it does not mean that every qualification at that level has the same content, size or assessment method. The government’s qualification-level guide lists both the numbered and letter-graded GCSEs.
U means ungraded. It is given when there are not enough marks for grade 1. Grade 1 is still an awarded GCSE grade, so it should not be treated as the same result as U.
Grades 3, 2 and 1 are at Level 1. Grades 9 to 4 are at Level 2, as are the former A* to C grades. Qualifications at the same level can still serve different purposes, which matters when comparing a GCSE with an alternative such as Functional Skills.
In England, grade 4 is commonly described as a standard pass and grade 5 as a strong pass. Both are Level 2 grades. The terms help describe attainment, but they do not create one entry rule for every college, apprenticeship, university course or job
Suppose Oriana has grade 4 in English and wants to study A-level psychology. She has reached the GCSE Level 2 threshold, but her sixth form may still ask for grade 5 or 6 as part of its own admissions criteria. That higher requirement does not turn her grade 4 into a failed GCSE.
There is no exact grade-by-grade conversion between the 9–1 and A*–G scales. Ofqual identifies only three points where the bottom of a numbered grade is comparable with the bottom of an old letter grade:
This is why charts that state “8 = A*” or “6 = B” are too precise. Grades 7, 8 and 9 together cover the old A and A* range, rather than each number replacing one particular letter.
Sam, for example, has an old grade C in English and sees a vacancy asking for grade 4. Ofqual treats the bottom of grade 4 as comparable with the bottom of the old C, so Sam should enter the C shown on his certificate rather than inventing a numbered grade.
Grade boundaries are set after exams have been taken and marking is nearly complete. Exam boards use statistical evidence and senior examiners’ judgement to maintain comparable standards when papers differ in difficulty. If a paper is harder, its raw-mark boundaries may be lower; if it is easier, they may be higher.
Ofqual also confirms that there is no quota requiring a fixed number of students to pass, fail or receive a particular grade. Its guide to how GCSE and A-level grading works explains the process in more detail.
A raw mark is the number of marks awarded for a student’s work. A grade boundary is the minimum raw mark needed for a particular grade in that exam series.
For example, two students taking different specifications could both score 65% and receive different grades because the papers and boundaries are not the same. A useful boundary must therefore match the subject, exam board, specification, tier and exam series. General charts claiming that a particular percentage always produces the same GCSE grade are misleading.
England, Wales and Northern Ireland all offer GCSEs, but they do not use one identical grading system. Scotland has a separate national qualification structure.
Made-for-Wales single-award GCSEs use A* to G. New double-award GCSEs use the eight-point scale A*A*, AA, BB, CC, DD, EE, FF and GG.
The new double awards in English Language and Literature, Cymraeg Language and Literature, and Mathematics and Numeracy began teaching in September 2025 and will first be awarded in summer 2027. The new Sciences double award began teaching in September 2026 and will first be awarded in summer 2028.
Qualifications Wales explains that legacy and new double-award scales will both appear in summer 2027, with all double awards moving to the new eight-point scale from summer 2028. See the exact Qualifications Wales grading update.
CCEA GCSEs use letter grades and include C*. The change took effect in summer 2019. Other awarding bodies also offer GCSEs in Northern Ireland, so qualifications from bodies such as AQA, OCR, Pearson and Eduqas may use number grades. nidirect’s GCSE guidance confirms both arrangements.
Scotland does not use GCSEs as its mainstream school qualification system. Its National Qualifications include National 5, Higher and Advanced Higher, which are graded A to D. Qualifications Scotland’s results guidance explains how these grades are reported. They should not be converted grade for grade into England’s 9–1 scale.
In England, some learners on 16 to 19 study programmes or T Levels who did not achieve grade 4 or above in GCSE English or maths by the end of Year 11 must continue studying an approved qualification. This is a condition attached to institutional funding, not a UK-wide law requiring every person below grade 4 to keep resitting the same GCSE.
Under the 2026 to 2027 condition-of-funding guidance:
For instance, a full-time college student with grade 3 in maths would normally continue with GCSE maths. A student starting from grade 2 may instead follow another approved route towards Level 2.
The rule applies only to eligible learners and programmes in England. The guidance includes age, programme-length and exemption criteria, including specific arrangements for some learners with education, health and care plans and some overseas qualifications.
Combined Science produces a double grade, while tiered subjects limit the range of grades available. Ofqual’s 2026 student exam guide gives the current ranges for England.
Students receive a pair of grades, such as 9–9, 9–8, 8–8 or 8–7, with the scale continuing down to 1–1. The pair records one double-award qualification, which is the size of two GCSEs; it is not two separate single-science results.
Yes. Foundation tier offers grades 5 to 1, including 5–5 to 1–1 in Combined Science. Higher tier offers grades 9 to 4, including 9–9 to 4–4 in Combined Science. Students who narrowly miss grade 4 on Higher tier may receive grade 3, or 4–3 in Combined Science.
The tiered subjects listed by Ofqual for 2026 are maths, Combined Science, biology, chemistry, physics, statistics and modern foreign languages. A grade 4 or 5 has the same value whether it was achieved on Foundation or Higher tier.
A: Grade 3 is an awarded GCSE grade at Level 1. It is more accurate to describe it as below the grade 4 Level 2 threshold than to treat it as the same as U. Whether grade 3 is enough depends on the course, job or other purpose for which the result is being used
A: Yes. Enter the letter grade exactly as it appears on the certificate. If an online form accepts only number grades, ask the employer how it wants an older result recorded rather than changing the grade yourself.
A: No. They are different qualifications, although both sit at Level 2 and may meet the same requirement in some settings. England’s condition-of-funding rules, for example, allow Functional Skills Level 2 for some learners, but a particular employer or education provider may set different entry criteria.
A: Yes. Adults can enter as private candidates, but they must find a school, college or other exam centre that accepts external entries. Ofqual’s 2026 private-candidate guidance confirms that not every centre accepts them, so arrangements should be made well before the entry deadline.
A: Not automatically. International GCSEs are separate qualifications, and the grading scale depends on the awarding organisation. Under England’s 2026 to 2027 condition-of-funding rules, an International GCSE can count as prior attainment at the required grade, but it cannot be chosen as the qualification studied to meet that funding condition.
A: C* is part of CCEA’s GCSE letter scale in Northern Ireland and appears between B and C. If Ethan has a C* and an English college application asks for number grades, he should record C* as awarded and ask the admissions team to apply its own comparison rather than relabelling the result himself.
