How GCSEs Work: Subjects, Grades and Exam Season

GCSEs are the main qualifications taken by pupils in England at around age 16, at the end of a two-year course in Years 10 and 11. Pupils usually sit between seven and eleven subjects, graded on a scale from 9 (highest) to 1, with most assessment by written exams held in late spring and results published in August. Rules differ in Wales, Northern Ireland and Scotland, so this page concentrates on England and notes the differences at the end.

What GCSE stands for and who takes them

GCSE stands for General Certificate of Secondary Education. Study for most subjects begins in Year 9 or Year 10 and lasts two or three years. Final exams in England and Wales fall mostly between April and June, and results arrive in August, according to Wikipedia.

GCSEs are set by exam boards, called awarding organisations, which are regulated by Ofqual in England. In England the main boards are AQA, Pearson Edexcel and OCR. Schools choose which board’s specification to teach for each subject.

Which subjects are compulsory?

In England, English, maths and science form the core of what pupils take. Beyond that, pupils choose options, often including a language, a humanities subject and creative or practical courses, though choices depend on what each school offers.

The English Baccalaureate has been a performance measure for schools rather than a qualification. It counts English language and literature, maths, science, a language, and history or geography. The Curriculum and Assessment Review recommended dropping it as a headline measure, so check the Department for Education for the current position. Pupils can take other combinations, and many do.

English language and maths carry extra weight because of the post-16 rule explained below.

How the 9 to 1 grades work

England replaced the old A* to G letters with numbers, starting with English language, English literature and maths in 2017, then rolling the change out to other subjects. Grade 9 is the highest and U means ungraded.

  • Grade 4 is described by the Department for Education as a standard pass, and it is the grade that replaced the old C as the benchmark.
  • Grade 5 is described as a strong pass.
  • Grade 8 is described as equivalent to the old A, and grade 9 is set above the old A, reserved for the highest performers.

The exact match between old and new grades is not one to one. The Department for Education’s factsheets on the new GCSE grading scale explain what standard and strong passes mean for pupils, parents and employers.

Tiers and papers

Some subjects are tiered. Foundation tier papers cover grades 1 to 5, and higher tier papers cover grades 4 to 9, with a grade 3 available to a pupil who narrowly misses a 4. Tiering has been reduced, and English subjects are no longer tiered, according to Wikipedia. Maths, science and some other subjects keep tiers, so pupils are entered at the level that suits them and the school decides in discussion with the pupil.

Coursework and assessment

Most GCSEs in England are now assessed entirely by exams at the end of the course. Non-exam assessment (coursework-style projects and performances) remains mainly in subjects such as design and technology and performing arts. Spoken English is reported as a separate endorsement alongside the English language grade, and science practical work is endorsed rather than graded.

Exam season

Exam season covers a few weeks around May and June. Pupils get a timetable from their school, and revision usually runs for months beforehand. Results are published in August.

Some practical points for families:

  • Check which board and specification each subject uses, because the content differs.
  • Use past papers and mark schemes, which boards publish.
  • Ask the school about access arrangements early, for example extra time.

What happens after GCSEs

At 16, young people in England stay in education or training until 18, through sixth form, college, an apprenticeship or work with training. Students who do not reach grade 4 in English or maths are generally expected to continue studying those subjects post-16. Under the Department for Education’s 16 to 19 funding condition, students with a grade 3 must study towards a GCSE, while those with grade 2 or below may instead take a level 2 Functional Skills qualification. The rules are updated for each academic year, so check the current guidance.

Grades matter for post-16 courses, but they are one input. Sixth forms set their own entry requirements, and A-level choices follow on from GCSEs. For an example of how the next stage of grading is discussed, see a reply on preparing for the new A* grade at A level, and for wider reading on schools and learning there are the feature articles on education.

How it differs in the rest of the UK

  • Wales still uses A* to G grades for most GCSEs, with WJEC as the main board and Qualifications Wales as regulator.
  • Northern Ireland uses A to G with an extra C grade, and CCEA is the board and regulator.
  • Scotland mainly uses a different system, the Scottish Qualifications Certificate, with National 4 and 5 as the comparable awards.

Qualification systems change, so check the relevant national body.

Frequently asked questions

What is a good GCSE grade?

Grade 4 is a standard pass and grade 5 a strong pass in England. What counts as good depends on what comes next, as sixth forms and courses set their own requirements.

How many GCSEs do you need?

There is no fixed number. Pupils typically take seven to eleven, and the important ones are usually English language and maths.

Can GCSEs be retaken?

Yes. English and maths are the most common resits, and the rules for post-16 students depend on the grade achieved. Ask the school or college.

Are GCSEs graded on a curve?

Grade boundaries are set each year by the exam boards under Ofqual’s regulation, so that standards are comparable over time. Pupils are not simply ranked against each other.
