Cambridge IGCSE was first examined in June 1988 (introduced for first teaching in September 1986). At the same time, the GCSE was introduced in the UK.

Cambridge IGCSE assessment takes place at the end of the course and can include written, oral, coursework and practical assessment. This broadens opportunities for students to demonstrate their learning, particularly when their first language is not English. In many subjects there is a choice between core and extended curricula, making Cambridge IGCSE suitable for a wide range of abilities.

Grades are benchmarked using eight internationally recognised grades, A* to G, which have clear guidelines to explain the standard of achievement for each grade.

Cambridge IGCSE examination sessions occur twice a year, in June and November. Results are issued in August and January.
