iGCSE curriculum: a plain-English overview

If you've just come across the term iGCSE and you're trying to work out what it is, this piece is for you. The iGCSE (International General Certificate of Secondary Education) is a two-year secondary school qualification, typically taken by students aged 14 to 16. It's the international cousin of the UK GCSE, designed for students at international schools, private schools abroad, and increasingly at UK independent schools too.

Two big exam boards run the iGCSE: Cambridge Assessment International Education (Cambridge International) and Pearson Edexcel. Cambridge International offers it as Cambridge IGCSE, and Pearson runs it as the Edexcel International GCSE. Both are recognised by universities and employers around the world, and both cover a similar age group and format.

The rest of this article walks through what subjects are covered, how the course is taught, how it's assessed, and what students usually do next.

The iGCSE is not a single fixed curriculum. It's a menu of subjects, and each school builds its own timetable from that menu. Cambridge International offers over 70 iGCSE subjects, and Pearson Edexcel offers a wide range too, so the choice is genuinely broad.

Subjects fall into a few main areas:

• Sciences: Biology, Chemistry, Physics, and combined science options such as Cambridge's Co-ordinated Sciences.
• Mathematics: including core and extended pathways so students can go deeper if they're strong at maths.
• English: usually English as a First Language or English as a Second Language, plus English Literature as a separate subject.
• Humanities: History, Geography, Economics, Business Studies, Global Perspectives, Religious Studies.
• Languages: a long list including French, Spanish, Mandarin, Hindi, Arabic, German, and many more, often available at both first-language and foreign-language levels.
• Arts and technology: Art and Design, Music, Drama, Computer Science, Design and Technology, ICT.

Most students take somewhere between five and ten subjects, though the exact number depends on the school and the student. Many international schools make Mathematics, English, and at least one Science compulsory, and then let students choose the rest from humanities, languages, and the arts.

In practice, a typical student might take Maths, English, one or two sciences, a humanity like History or Geography, a language, and one or two extras that reflect their interests. It's a system that gives schools flexibility, which is why the iGCSE feels a bit different from school to school even though the underlying qualification is the same.

The iGCSE is taught over two school years. In most schools this is Years 10 and 11 (using the English system), or Grade 9 and Grade 10 in schools that use American or Indian year labels. Students study all of their chosen subjects across both years and sit final exams at the end.

Teaching is done through a mix of classroom lessons, textbook work, past-paper practice, and, for some subjects, practical work. Sciences involve practical experiments, and subjects like Art, Design and Technology, Music, and Drama have coursework or performance-based elements that are marked separately from the written exams.

That said, the iGCSE is largely exam-based. Cambridge International has moved most of its subjects to purely written-exam assessment, though practical skills in the sciences are still tested, often through a written practical paper rather than a graded lab session. Pearson Edexcel takes a similar approach.

There's no ongoing coursework component in the way some qualifications work. Students build knowledge across the two years, then everything comes down to the final papers at the end of Year 11.

Grading depends on the board. Pearson Edexcel uses the 9 to 1 scale across all its International GCSEs, with 9 as the top grade and 1 as the lowest pass, matching the reformed UK GCSE. Cambridge International runs A* to G as its default scale, and schools can opt in to 9 to 1 as an alternative on a subject-by-subject basis. It's worth checking the individual subject page on the exam board's website to see which scale applies at your school.

Each subject has its own specification (the official document that lays out what students need to know) and its own paper structure. In a typical subject, students might sit two or three papers, each testing a different skill or topic area. Papers vary in length from around 45 minutes for shorter components up to two hours or more for longer ones.

For example, Cambridge IGCSE Biology has separate papers for multiple choice, structured questions, and practical skills, while a language subject might have listening, reading, writing and speaking papers spread across the assessment window.

Exams are sat in June for most subjects, with a November series also available for some. Results come out a few months later.

Once students finish iGCSEs, they usually move on to a two-year post-16 course. The most common routes are:

• Cambridge AS and A Levels or Pearson Edexcel International A Levels, which are subject-based and lead into UK-style university applications.
• The IB Diploma Programme, which is a broader six-subject qualification with a theory of knowledge and extended essay component.
• The IB Career-related Programme, which combines IB subjects with career-focused study.

Which route a student takes usually depends on the school. Some international schools offer only A Levels, some only the IB, and others let students choose between them.

In India, a smaller number of iGCSE students switch to the CBSE or ICSE board for Classes 11 and 12, usually because they want a route that lines up more closely with Indian universities. It's not common, but it does happen.
