Cambridge International (CAIE) is one of the two dominant providers of the British-curriculum pathway in international schools, alongside Pearson Edexcel. It runs a fully aligned vertical from Cambridge Primary through Lower Secondary, IGCSE, AS-Level and A-Level. The depth and rigour of the Cambridge specification is recognised globally and shapes admissions standards in markets as varied as the UK, the US, the Gulf, Southeast Asia and East Africa.
What Cambridge offers
The vertical runs across four stages: Primary (ages 5 to 11), Lower Secondary (11 to 14), Upper Secondary culminating in IGCSE (14 to 16), and Advanced (16 to 18) ending in AS and A-Level. International schools rarely follow the full vertical; most pick up at IGCSE. The Cambridge Primary and Lower Secondary stages are sometimes used as a structured spine alongside another curriculum (IB Primary Years Programme, for instance) rather than as the sole framework.
Cambridge IGCSE in detail
Cambridge IGCSE is the most widely taken international qualification at age 16, with over 70 subjects on offer. Cambridge IGCSE Mathematics, English (First Language and Second Language), and the three sciences are the most-taught subjects globally. The exam is graded A* to G; from 2017 Cambridge introduced 9-1 grading on selected subjects to align with UK GCSE reform.
Cambridge A-Level
The Cambridge International A-Level is a two-year programme with optional AS-Level milestone at the end of Year 12. Unlike the UK domestic A-Level, Cambridge International retains AS as a meaningful standalone qualification, which gives students and schools more flexibility. Strong Cambridge schools typically offer 18 to 25 A-Level subjects.
Cambridge vs Edexcel
The two boards are largely interchangeable in terms of university recognition. Cambridge tends to have more global market share; Edexcel has slightly broader subject choice in some areas. For depth on the choice, see Cambridge vs Edexcel IGCSE.
University recognition
Universally accepted by UK universities and most major global university systems. US colleges typically expect AP equivalents alongside Cambridge A-Levels for STEM-heavy applications. Canadian universities have published equivalence tables. For specifics see our country-by-country recognition guide.
