The General Certificate of Education (GCE) is a subject-specific family of academic qualifications that awarding bodies in England, Wales, Northern Ireland, Crown dependencies and a few Commonwealth countries, notably Sri Lanka, Pakistan, Malaysia and Singapore, confer on students. (The Scottish education system is different from those in the other countries of the United Kingdom).
The GCE is composed of three levels; they are, in increasing order of difficulty:
The General Certificate of Education (GCE) was established in England and Wales after the Second World War, along with the Certificate of Secondary Education (CSE). Both these examinations set out to provide a national standard of public examinations, within the wider reform of secondary education under the Education Act of 1943 (The Baker Act). Prior to the war, the standards of education offered by different local education authorities varied widely, and whilst some urban education authorities supported Technical Schools, others, particularly in rural areas, offered only "Higher Elementary" education to the majority of pupils. The Education Act of 1943 established a strategy to deliver a universal secondary education system fit for the post-war social and economic reconstruction of the country. It envisaged three distinct types of schools: Grammar Schools, Technical Schools and Secondary Modern Schools, all to be provided at public expense, and each of which where intended to provide education appropriate to the abilities and aspirations of their pupils. The syllabi and examination standards of both GCE and CSE should be seen in this context.
The General Certificate of Education set out to provide a national standard for matriculation to university undergraduate courses. It had two levels, Ordinary and Advanced, which rapidly became known throughout the education system as "O levels" and "A Levels." Ordinary levels were usually taken at the age of 16 - the statutory minimum school leaving age - and Advanced levels at the age of 18 after a further two year course. Both the O level and A level courses were examined by subject and matriculation (the minimum standard for university entrance) was set at five passes in different subjects, of which two had to be at A level.
For matriculation purposes the highest grade pass of a subject taken at CSE level was considered a pass at O level.
In the English education system both the GCE and CSE examinations were replaced in the 1980s with the General Certificate of Secondary Education (GCSE), which set out to provide a multi-level examination system catering for all abilities of secondary school pupils. This supported the ongoing development of a comprehensive education system, which recognised education as a fundamental human right, and sought to avoid the risk of writing children off at the age of eleven which had become apparent as an undesirable by-product of the 11+ selection system
Though the GCE was considered a national standard there was no national syllabus, and it was run by a number of different Examination Boards, each of which set their own syllabi and papers. These included the "Northern Universities Joint Matriculation Board"—generally known as the JMB, The University of London ("The London Board") and the "Oxford and Cambridge Board."
Examination sessions were held bi-annually in May and November and successful candidates received a certificate listing the subjects they had passed in the session, together with the marks achieved in each. In the earliest years of the system subject marks were given as percentages at both Ordinary and Advanced Level. In later years ordinary level pass marks were graded 1-6, with 1 being the highest. The grading system was further simplified in 1975 when the six pass marks were reduced to three, graded A, B, C. In normalised terms at O level the lower bound for A was then 70% and the lower bound for C 45%. For matriculation purposes C was the lowest pass grade. D, E and F grades were also shown for the first time—indicating that a paper had been sat but the student had not achieved a pass mark.
In the late 1970s, A level certificates showed grades from A to F. At A level E was considered a pass for matriculation, and corresponded to 30%. All these examinations were closed book and Art was the only subject for which any assignment outside the examination hall contributed to the final mark.
GCE Ordinary and Advanced levels did not exist within the Scottish Education system, but had an equivalent, administered by the Scottish Education Department, part of the Scottish Office. This predated the GCE and also had two levels, originally called Higher Grade and Lower Grade. Lower grade was renamed the Ordinary Grade around the time that the GCE O level was established. The two were exact equivalents. Higher grade however was a lower level course than the A level and taken over one year—preparing students for entry to Scottish Universities which had 4-year degree courses, traditionally commenced at the age of 17.
The Scottish "O grade" was replaced by a new examination, the "standard grade" phased in over several years in the late 1980s. This in turn has been replaced (2015–18) by a new examination the "National Level 5", however the Higher examination remains the matriculation standard for Scottish Universities, though most school leavers destined for university today remain for a further year in school taking further courses.
The secondary education system in Northern Ireland continues to use the GCE Ordinary and Advanced level system. It also retains selection to grammar school by the 11+ examination: A public examination which selects children as suitable for an academic (essentially a liberal arts) secondary syllabus from the age of eleven to eighteen.
Though the GCE was replaced in the English Education system in the 1980s, some examination boards continue to offer Ordinary and Advanced level examinations to English Language schools overseas. This enables these students to obtain matriculation instantly recognisable to British Universities.
Significant numbers of private schools in England have also reverted to preparing pupils for GCE examinations.
Letter grades are used, with A, B, C, D, and E representing a pass and U (unclassified) representing a fail. After leading British universities had expressed concerns that the A grade alone would no longer be enough to distinguish the most exceptional candidates, the A* grade was introduced (GCSE, the replacement of GCE and CSE)[clarification needed] for students who achieve 80% and above in the overall A-Level qualification and achieve 90% and over in all A2 (this applies to GCSE and not GCE but may apply to CSE) modules.
In the past, a Scholarship / Special / "S-Level" / Advanced Extension Award (AEA) existed; an Advanced Supplementary Level (designated "AS Level" but not to be confused with the modern-day AS Level, which is lower than the A Level) qualification was also formerly available.
The General Certificate of Education Advanced Level (GCE "A Levels") is an entry qualification for universities in the United Kingdom and many other locations worldwide.
The US equivalent of the GCE for admissions would be, roughly, the High School Diploma. However, in England and Wales, the high school diploma is considered to be at the level of the General Certificate of Secondary Education (GCSE), which is awarded at Year 11. For college and university admissions, the high school diploma may be accepted in lieu of the GCSE if an average grade of C is obtained in subjects with a GCSE counterpart.
As the more academically rigorous A Levels awarded at Year 13 are expected for university admission, the high school diploma alone is generally not considered to meet university requirements. Students who wish to study in the United Kingdom may additionally participate in the Advanced Placement (AP) or International Baccalaureate (IB) programs, which are considered to be at the level of the A Level qualifications and earn points on the UCAS Tariff, or may opt to take A Level examinations in British international schools or as private candidates. Standardized tests, such as the College Board's SAT and SAT Subject Tests or the ACT, may also be considered.
The Universities and Colleges Admissions Service (UCAS) recommends that in addition to a high school diploma, grades of 3 or above in at least two, or ideally three, Advanced Placement exams may be considered as meeting general entry requirements for admission. The IB Diploma may also be accepted. For College Board tests, a minimum score of 600 or higher in all sections of the SAT or a minimum score of 26 or higher in all sections of the ACT along with a minimum score of 600 in relevant SAT Subject Tests may be considered as meeting general entry requirements for admission.
Bangladesh also has the GCE A-Level and GCE O-Level. There are many schools which follow the British Curriculum.
Up to now, most schools in Brunei are under GCE, the levels are of O-level, A-level, and AS-level[clarification needed] Examinations are conducted by the Examinations Department of Brunei Darussalam.
In Cameroon, the GCE Ordinary Level examination is a 3-year course program starting from Form 3 to Form 5 (Years 9 to 11). It is usually written in Form 5 (Year 11) in Secondary schools, meanwhile the GCE Advanced Level examinations are written in Upper 6 (Year 13) in High school. Most Secondary schools in Cameroon which do the English form of education and write both the GCE A-Level and O-Level examinations were boarding schools but since then many day schools were opened which offered a complete GCE course and anyone wishing to have an English education are no more obliged to go for boarding schools. The GCE saw changes in syllabus content at the ordinary and advanced levels in some science subjects in order to adapt to the world's advancing school program.
During Easter break around March, students in these boarding schools stay for GCE courses for a week and a few days in school for extra classes in order to cover up their syllabus. At the end of the school year, all students in other classes except the GCE candidates leave and they stay for their Revisions and preparation towards the upcoming exams in Late-May. Once the candidates finish writing in early June, they all return to their various homes, waiting to hear their results. The same thing applies for GCE candidates in day schools. The results for the GCE O-Level and A-level exams in Cameroon are announced around mid-July.
The two educational qualifications, Hong Kong Certificate of Education Examination (HKCEE) and Hong Kong Advanced Level Examination (HKALE), were the two school-leaving exams until they were replaced by the Hong Kong Diploma of Secondary Education (HKDSE). The HKDSE eventually replaced the two exams by only having one public exam in high school year 3 (year 12). English Schools Foundation (though some schools are also adopting the IB Diploma program).
GCE examinations in Malaysia were used to be conducted by the [University of Cambridge Local Examinations Syndicate], when two agencies of the Malaysian Ministry of Education took over the role with UCLES retaining an advisory role on standards.
The GCE O-Level equivalent is the Sijil Pelajaran Malaysia (SPM, formerly known in English as the Malaysian Certificate of Education (MCE)), conducted by the Lembaga Peperiksaan Malaysia (LPM, the Malaysian Examinations Syndicate). The SPM is taken by all fifth-year secondary school students in Malaysia. The SPM English Language paper is graded separately by the LPM and by UCLES (which still awards a GCE O-Level for the paper), and both grades are displayed on the results slip.
The GCE A-Level equivalent is the Sijil Tinggi Persekolahan Malaysia (STPM, formerly known in English as the Malaysian Higher School Certificate (HSC)), conducted by the Majlis Peperiksaan Malaysia (MPM, the Malaysian Examinations Council). The STPM is taken by students after a one-and-a-half-year sixth form course. The STPM is accepted for admission to universities worldwide.
Pakistan also runs the GCE education level. Some of Pakistan's top schools offers this medium of education. GCE is mostly offered by private schools in Pakistan. The number of entries for GCE qualifications for O Levels and A Levels has been increasing in Pakistan. The entries for O Levels qualifications in Pakistan grew by 5% in 2015-16 from the previous year, and increased by 8% for A Levels. O Levels and A Levels are considered to be equivalent to the local board of intermediate and secondary education (BISE) education system in Pakistan. A Pakistani student currently holds the world record for attaining the highest number of A's in A-Level. Haroon Tariq scored 30 A's in GCE Advanced Level. Haroon Tariq also holds the world record for most A's (28) in O-levels. He also has 29 A grades in IGCSE which is also a world record. Haroon Tariq has a total of 7 world records. 
Students take the O-Levels after completing Secondary 4 at age 16 for the Special and Express streams, or Secondary 5 at age 17 for the Normal Academic Stream. After that, they have the option to go on to a junior college for two years in preparation for the A-Levels or study a vocational trade and earn a diploma at a polytechnic or technical school. Increasingly, students who perform well in school are given the option to bypass the O-levels and take the A-Levels, in a scheme dubbed the integrated programme (also known as the through-train programme).
In Sri Lanka GCE Ordinary Level and GCE Advanced Level examinations are conducted by the Department of Examinations of the Government of Sri Lanka. The GCE(O/L) is normally conducted in the month of December and GCE (A/L)s are conducted in the month of August. They are conducted on an island-wide examination centres on same time. Examination entrance is restricted by a minimal number of formal school going years and laboratory field work. The majority of candidates enter the exams via their respective schools, while candidates who have finished school education can also apply as a private candidate.
The O/L examination is regarded as the qualification examination for starting on GCE(A/L). Specialization streaming is depended on the grades obtained for subjects in the O/L. The country's reputed schools admit students to their A/L, depending on the O/L grades.
The Sri Lankan University Grants commission determines the cut-off points for the selection of students to the Sri Lankan universities according to the grade points obtained in the A/L examinations based on the standard normal distribution.
