What Is the IGCSE? A Clear Guide for Parents

What the IGCSE is

The IGCSE (International General Certificate of Secondary Education) is a set of subject qualifications typically taken by students aged 14–16, usually over two academic years. It is the international counterpart of the UK GCSE and is the standard qualification at this stage in most international schools across Europe.

Each subject is a separate qualification with its own syllabus and exams. A typical student takes between six and ten subjects, combining compulsory subjects set by their school with personal choices.

The two main exam boards

Most international schools use one of two awarding bodies: Cambridge International Education (Cambridge IGCSE) or Pearson (Edexcel International GCSE). The subjects overlap heavily, but syllabuses, paper structures and mark schemes differ — which is why effective support must be board-specific.

Your child’s school determines the board for each subject. It is common for a school to use Cambridge for some subjects and Edexcel for others.

How grading works

Edexcel International GCSEs are graded 9–1, with 9 the highest. Cambridge IGCSEs are graded either A*–G or 9–1 depending on which syllabus code the school has entered. Several Cambridge subjects are also tiered: Core papers cap the maximum grade, while Extended papers give access to the top grades.

If your child is in a tiered Cambridge subject, the tier decision matters and is worth discussing with the school — and with a tutor who has seen the student’s work — well before entry deadlines.

When to consider extra support

The most common reasons families seek tutoring are: a persistent gap in one subject, preparation for the final exam season, a push from good grades to top grades, or a school transition that has left gaps in coverage. Earlier support is generally more effective than a late rescue, because it allows fundamentals to be repaired before exam pressure begins.
