CAIE stands for Cambridge assessment international education and is affiliated to Cambridge press and assessment (Cambridge press and assessment) of Cambridge University. CAIE is a non-profit education/examination institution that mainly provides education systems and key examinations for international primary and secondary school students. Among them, the series of assessment and education systems it created for high school students are highly praised and widely recognized.

CAIE's international examination system can be considered a copy of the primary and secondary school system in England/Wales. For example, IGCSE is derived from England's gcse, and international A-Level is also developed from England's local A-Level. However, CAIE's replication is undoubtedly successful. Even though the examination bodies have been abolished by the English government, the examinations held by CAIE are still highly recognized internationally.

IGCSE stands for International General Certificate of Secondary Education. In England, its predecessor was GCSE, which was founded in 1986 as a supplement and reform to the 1951 O-level.

Before the GCSE was abolished in England in 2023, it had been the final exam for 10th grade students in England, similar to the Chinese National Higher Education Examination. GCSE can enable students to enter technical schools and be recognized by many companies and employers in society, but they cannot apply for university. The ranking system is as follows: above 90% of candidates will get a grade of A*; below 90%, above 80% of the candidates will get a grade of A; below 80%, above 70% of the candidates will get a grade of B; low The score of candidates who are above 70% and above 60% is C; the score of candidates who are below 60% and above 50% is D; the score of candidates who are below 50% and above 40% is E; the rest are unqualified U.

In 1986, when gcse began to be used in England, CAIE also followed England's lead and introduced IGCSE as a supplement to its international o-level. It gained international recognition and gradually replaced the status of international o-level. Although gcse cannot apply to regular universities in the UK, IGCSE can apply to some universities in the United States, provided that students must obtain extremely good results (see the secondary topic "University Application and Recognition" for details). Although in England, students spend two years studying for GCSE starting in grade 9, in many Cambridge schools in other countries, teachers compress the IGCSE course into 1 year of study.

IGCSE offers more than 70 subjects for students to choose from, including more than 30 language subjects. The syllabuses for these courses are aligned with the English education system. At the same time, IGCSE has also set up two forms of core version and extended version for each subject. The core version is simpler, but the extended version can better prepare students for future A-Level study.

A Level officially replaced the high school diploma originally issued by local high schools in England in 1951 as the university application examination in England, which is equivalent to China's college entrance examination. In 1986, the International A Level system was established on the basis of the A Level examination in England and is widely recognized by universities and governments around the world.

A Level offers 55 subjects, including no less than 20 language-related subjects. Students can freely choose subjects according to their own interests and application intentions.

A Level is divided into two parts, AS and A2, each part takes 1 year to study. There is an inheritance relationship between the two parts of knowledge. Students need to learn AS first and then A2. The AS grade is also part of the overall A2 grade. Teachers often believe that AS level requires students to spend more effort to master than A2.
