Overview
GCSE stands for General Certificate of Secondary Education. It is not a single exam: it is a qualification framework covering more than 60 individual subjects, and each student puts together their own set of subject exams rather than sitting one common test. GCSEs mark the end of compulsory secondary schooling in England, Wales and Northern Ireland and are usually taken over two years of study, at the end of what England and Wales call Key Stage 4.
Several awarding bodies set and mark GCSE exams under government oversight: AQA, Pearson Edexcel and OCR in England, WJEC (also trading as Eduqas) based in Wales, and CCEA in Northern Ireland. A school chooses which board's specification to teach for each subject, so two students at different schools can both hold a "GCSE in Maths" set by different boards, assessed to the same regulated standard.
Who can apply
GCSEs are mainly taken by school students around age 15–16, in Year 10 and Year 11 in England and Wales (Year 11 and Year 12 in Northern Ireland). Most state schools make English, maths and science compulsory, and students then choose further subjects from areas such as humanities, languages, arts and design and technology. Most students sit between eight and ten GCSE subjects in total.
GCSEs are also open to private candidates: home-educated students, adult learners, and people studying outside school who register directly with an approved exam centre rather than through a school.
Exam boards
| Board | Nation(s) | Regulator |
|---|---|---|
| AQA | England (available UK-wide) | Ofqual |
| Pearson Edexcel | England (available UK-wide) | Ofqual |
| OCR | England (available UK-wide) | Ofqual |
| WJEC / Eduqas | Wales (WJEC), England (Eduqas brand) | Qualifications Wales (WJEC in Wales); Ofqual (Eduqas in England) |
| CCEA | Northern Ireland | CCEA Regulation |
Ofqual, the Office of Qualifications and Examinations Regulation, oversees AQA, Pearson Edexcel, OCR and Eduqas in England. It works to keep a given grade standing for the same level of achievement from one year and one board to the next.
Exam pattern
Most GCSE subjects are assessed mainly by written exams sat at the end of the two-year course, usually a mix of papers testing different skills within the subject (for example a non-calculator and a calculator paper in maths, or separate papers for different skills in English). A number of subjects also include non-exam assessment — coursework, practical work or a portfolio — alongside the written papers; this is common in subjects such as art and design, music, and some science and technology courses.
Grading
England: GCSEs are graded on a 9-to-1 numeric scale, with 9 the highest grade and 1 the lowest. Grade 4 is counted as a "standard pass" and grade 5 as a "strong pass." Only three points are officially fixed against the old A*–G scale: the bottom of grade 7 lines up with the bottom of the old grade A, the bottom of grade 4 with the bottom of the old grade C, and the bottom of grade 1 with the bottom of the old grade G.
Wales: WJEC GCSEs are mostly still graded A*–G, with A* the highest grade, regulated by Qualifications Wales rather than Ofqual. From autumn 2026, new "double award" GCSEs (covering subjects taught across two linked GCSEs, such as Mathematics and Numeracy) move to an 8-point double-letter scale (AA, AA, BB, CC, DD, EE, FF, GG).
Northern Ireland: CCEA GCSEs are graded A*–G, with an added C* grade sitting between grade B and grade C since 2019, giving nine grade points overall. A student in Northern Ireland taking a GCSE set by an England-based board (AQA, Pearson Edexcel or OCR) instead receives a 9-to-1 grade for that subject.
Each board sets its own grade boundaries after every exam series, under the oversight of the relevant regulator, so the mark needed for a given grade can differ slightly year to year and board to board.
Important dates
For 2026, the main GCSE exam series runs through May and June, with individual subject exam dates set by each board and published on its own timetable. GCSE results are issued on the same day each year across England, Wales and Northern Ireland; for 2026 this is Thursday 20 August.
Fees
GCSEs are free for students at state-funded schools: the school registers students for their exams and pays the awarding body's entry fees directly, so families are not billed.
Private candidates are not covered by a school's entry and must pay to sit their exams. There is no single national fee: each exam board charges an entry fee per subject to the exam centre, and the centre adds its own administration and invigilation charge on top, so the total a private candidate pays in GBP varies from one approved centre to another.
How to apply
School students: your school registers you for each subject exam as part of your course; no separate application is needed.
Private candidates: find an exam centre on the relevant awarding body's list of centres that accept private candidates, register with that centre before its entry deadline (centres typically set this several months ahead of the exam series), and pay the centre's fee.
After the exam
GCSE results support progression to several next steps: A Levels, T Levels, apprenticeships, and other vocational or technical courses. Sixth forms and colleges commonly ask for a minimum of five GCSEs at grade 9–4 (or the equivalent), including English and maths, to start A Levels, though specific subjects may ask for higher grades. In England, a student who has not reached at least grade 4 in English and in maths by age 16 is required, under the government's post-16 condition of funding rules, to keep studying towards that grade alongside their next course.
Students can resit a GCSE in a later exam series if they want to improve a grade; English and maths GCSEs can also be resat in a November series in England, as well as in the main May–June series.
Preparation tips
Check which board's specification your school is teaching for each subject — past papers and mark schemes from the wrong board can be misleading.
Build a revision timetable around your own exam dates rather than a generic calendar, since subjects can fall early or late in the May–June window.
For subjects with non-exam assessment (coursework or practical work), keep track of your own internal deadlines, which usually fall well before the written exams.
Practise under timed conditions with real past papers from your own exam board, not just revision guides.
FAQs
Is GCSE a single exam?
No. GCSE is a qualification framework covering dozens of separate subjects. A student takes a set of individual subject exams, usually eight to ten of them, not one combined test.
What grade counts as a pass in GCSE?
In England's 9-to-1 system, grade 4 is a "standard pass" and grade 5 a "strong pass." Wales and Northern Ireland mostly still use A*–G grading, where grade C is broadly treated as the pass level.
Do England, Wales and Northern Ireland all use the same GCSE grades?
No. England uses a 9-to-1 numeric scale. Wales mostly uses A*–G for WJEC GCSEs, moving some subjects to a double-letter scale from 2026. Northern Ireland's CCEA uses A*–G with an added C* grade, though NI students can also take England-based boards' subjects on the 9-to-1 scale.
Can adults sit GCSEs?
Yes. Adults and other private candidates can register directly with an approved exam centre to sit GCSEs, paying the centre's own fee, rather than going through a school.
