Through England, English literature and Mathematics

Each GCSE qualification is offered as a specific school subject, with the most commonly awarded being English literature, English language, mathematics, science (combined and triple), history, geography, religious studies, art, design and technology (D&T), business studies, music, physical education, computer science and modern foreign languages (e.g. Spanish, French, German) (MFL).

The Department for Education has drawn up a list of core subjects known as the English Baccalaureate for England based on the results in eight GCSEs, which includes both English language and English literature, mathematics, science (physics, chemistry, biology, which are a part of the separate science course (or triple science), computer science), geography or history and an ancient or modern foreign language. English language and mathematics are the two GCSEs that you must get a passing grade in (a 4) and in exceptional circumstances – such as extreme illness – it has been known for students to take only these two, however it severely limits the subjects they can take as A levels.

Studies for GCSE examinations take place over a period of two or three academic years (depending upon the subject, school and exam board). They usually start in Year 9 or Year 10 for the majority of pupils, with around two mock exams – serving as a simulation for the actual tests – normally being sat during the first half of Year 11 and the final GCSE examinations nearer to the end of spring, in England and Wales.

History

Before the introduction of GCSEs pupils took the CSE (Certificate of Secondary Education) or the more academically challenging O-Level (General Certificate of Education (GCE) Ordinary Level) exams or a combination of the two, in various subjects. The CSE broadly covered GCSE grades C–G or 4–1 and the O-Level covered grades A*–C or 9–4, but the two were independent qualifications, with different grading systems. The separate qualifications were criticised for disadvantaging the bottom 42% of O-Level entrants, who failed to receive a qualification, and the highest-achieving CSE entrants, who had no opportunity to demonstrate higher ability.

In their later years O-Levels were graded on a scale from A to E, with a U (ungraded) below that. Before 1975 the grading scheme varied between examination boards, but typically there were pass grades of 1 to 6 and fail grades of 7 to 9. However, the grades were not displayed on certificates. Before grades were introduced, actual percentage marks were given, to the nearest 5%, the pass mark being 45%.

The CSE was graded on a numerical scale from 1 to 5, with 1 being the highest and 5 the lowest passing grade. Below 5 there was a U (ungraded) grade. The highest grade, 1, was considered equivalent to an O-Level C grade or above, and achievement of this grade often indicated that the pupil could have taken an O-Level course in the subject to achieve a higher qualification. As the two were independent qualifications with separate syllabi, a separate course of study would have to be taken to convert a CSE to an O-Level in order to progress to A-level.

There was a previous attempt to unite these two disparate qualifications in the 1980s, with a trial ‘16+‘ examination in some subjects, awarding both a CSE and an O-Level certificate, before the GCSE was introduced. The final O-level/CSE examinations were sat in 1987.

Introduction of the GCSE

GCSEs were introduced in September 1986 to establish a national qualification for those who decided to leave school at 16 without pursuing further academic study towards qualifications such as A-levels or university degrees. The first GCSE exams were sat in 1988. They replaced the former CSE and O-Level qualifications, uniting the two qualifications to allow access to the full range of grades for more pupils. However, the exam papers of the GCSE sometimes had a choice of questions, designed for the more able and the less able candidates.

When introduced the GCSEs were graded from A to G, with a C being set as roughly equivalent to an O-Level Grade C or a CSE Grade 1 and thus achievable by roughly the top 25% of each cohort.

The Royal Alexandra & Albert School in Reigate, Surrey, trialled GCSE English in 1980. Those who passed would receive both a CSE and an O-Level certificate. There was still a separate English Literature O-Level exam.

Changes since initial introduction

Over time the range of subjects offered, the format of the examinations, the regulations, the content and the grading of GCSE examinations have altered considerably. Numerous subjects have been added and changed and various new subjects are offered in modern languages, ancient languages, vocational fields and expressive arts, as well as citizenship courses.

Introduction of the A* grade

In 1994 the A* grade was added above the grade A to further differentiate attainment at the very highest end of the qualification. This remained the highest grade available until 2017, when numerical grades were introduced (see below). The youngest pupil to gain an A* grade was Thomas Barnes, who earned an A* in GCSE Mathematics at the age of 7.

Mathematics tiers

Initially the mathematics papers were divided between three tiers: higher (able), intermediate (less able) and foundation (near unable), to cover different mathematical abilities. The higher level corresponded to grades A–C, the intermediate level to grades C–E, and the foundation level to grades E–G. However, it was later realised that students who sat the foundation level exam could not pass the subject at grade C, so this system was replaced by a two-tier arrangement whereby the intermediate and foundation levels were merged. This brought the subject into line with other subjects that typically had foundation and higher-level papers. This meant that somebody who sat the new foundation level could now achieve a grade C and thus pass.

With the introduction of numbered grades, the higher tier provides grades 9–3, with 3 being classed as a "safety net" grade, and the foundation tier provides grades 5–1.

2000s reforms

Between 2005 and 2010, a variety of reforms were made to GCSE qualifications, including increasing modularity and a change to the administration of non-examination assessment.

From the first assessment series in 2010, controlled assessment replaced coursework in various subjects, requiring more rigorous exam-like conditions for much of the non-examination-assessed work and reducing the opportunity for outside help in coursework.

2010s reforms

Under the Conservative government of David Cameron, various changes were made to GCSE qualifications taken in England. Before a wide range of reforms, interim changes were made to existing qualifications, removing the January series of examinations as an option in most subjects and requiring that 100% of the assessment in subjects from the 2014 examination series be taken at the end of the course. These were a precursor to the later reforms.

From 2015, a large-scale programme of reform began in England, changing the marking criteria and syllabi for most subjects as well as the format of qualifications and the grading system.

Under the new scheme, all GCSE subjects were revised between 2015 and 2018 and all new awards were to be on the new scheme by summer 2020. The new qualifications are designed such that most exams will be taken at the end of a full two-year course, with no interim modular assessment, coursework nor controlled assessment except where necessary (such as in the arts). Some subjects retain coursework on a non-assessed basis, with the completion of certain experiments in science subjects being assumed in examinations and teacher reporting of spoken language participation for English GCSEs as a separate report.

Other changes include the move to a numerical grading system to differentiate the new qualifications from the old-style letter-graded GCSEs, publication of core content requirements for all subjects and an increase in longer, essay-style questions to challenge pupils more. Alongside this a variety of low-uptake qualifications and qualifications with significant overlap will cease, with their content being removed from the GCSE options or incorporated into similar qualifications. A range of new GCSE subjects was also introduced for pupils to study from 2017, 2018, 2019, and 2020.

GCSE examinations in English and mathematics were reformed with the 2015 syllabus publications, with these first examinations taking place in 2017. The remainder were reformed with the 2016 and 2017 syllabus publications, leading to first awards in 2018 and 2019 respectively.

For GCSE Science, the old single-award "science" and "additional science" options are no longer available, being replaced with a double award "combined science" option (graded on the scale 9–9 to 1–1 and equivalent to 2 GCSEs). Alternatively, pupils can take separate qualifications in chemistry, biology and physics. Other removed qualifications include a variety of design technology subjects, which are reformed into a single "design and technology" subject with several options, and various catering and nutrition qualifications, which are folded into "food technology". Finally, several "umbrella" GCSEs such as "humanities", "performing arts" and "expressive arts" are dissolved, with those wishing to study those subjects needing to take separate qualifications in the incorporated subjects.

Implications for Wales and Northern Ireland

These reforms did not apply immediately in Wales and Northern Ireland, where GCSEs would continue to be available on the A*–G grading system. However, owing to legislative requirements for comparability between GCSEs in the three countries and allowances for certain subjects and qualifications to be available in Wales and Northern Ireland, some 9–1 qualifications were to be available and the other changes were mostly adopted in these countries as well.

In Northern Ireland, a decision was taken by Minister of Education, Peter Wier (DUP), in 2016 to align the A* Grade to the 9 Grade of the English reformed qualifications. The first award of the new A* grade was in 2019. A C* grade was also introduced in Northern Ireland to align to the 5 grade in England, again with first awarding in 2019. GCSEs in Northern Ireland remain modular and Science practicals can count towards the overall grade. Speaking and listening also remains a component of the GCSE English Language specification.

VCSE in Wales

A new brand of vocational qualifications, called VCSEs, will be introduced in Wales from September 2027.

Subjects taught under this new qualification will be:

  • Built Environment
  • Creative and Media Production, and Technology
  • Engineering
  • Hospitality and Catering
