An Updated Overview of Cambridge iGCSE Computer Science for Teachers
A Must-Read for International British School Teachers, including syllabus overview, assessment, teaching focus & top iGCSE resources.
Cambridge iGCSE Computer Science is a forward-looking qualification that equips students with the computational thinking, programming skills, and theoretical understanding needed in a digital world. Designed for learners aged 14–16, the course blends problem-solving with practical coding and a solid foundation in how computer systems work.
For teachers, delivering iGCSE Computer Science successfully requires a strong grasp of the latest syllabus requirements, assessment structure, and access to reliable, curriculum-aligned iGCSE resources. This guide summarises the official Cambridge specification for exams starting in 2026, helping you plan, teach and assess with confidence.
Why Teach Cambridge iGCSE Computer Science
Cambridge iGCSE Computer Science is increasingly popular in international British schools because it:
- Develops logical thinking and problem-solving skills
- Introduces students to real-world programming concepts
- Builds understanding of how digital systems operate
- Supports progression to A Level Computer Science, IB and STEM pathways
- Prepares students for a technology-driven future
The subject balances theory and practical skills, making it suitable for students with both academic and applied interests.
Overview of the iGCSE Computer Science Specification
The full syllabus PDF from Cambridge International outlines the subject content, assessment structure, and practical skills required for examination success. As with other Cambridge iGCSE subjects, the emphasis is on understanding and application, not rote learning.
Key Topics Covered
- 1 Data representation
- 2 Data transmission
- 3 Hardware
- 4 Software
- 5 The internet and its uses
- 6 Automated and emerging technologies

Assessment Structure Explained
Cambridge iGCSE Computer Science is assessed through:
- Paper 1 consists of short-answer and structured questions based on the first 6 topics, worth 75 marks
- Paper 2 consists of short-answer and structured questions based on the final 6 topics, worth 75 marks. It also includes a scenario-based question.
The exam series is offered in June and November (and March in some regions such as India).
Cambridge and Seneca Learning provide schemes of work, specimen papers, and examiner reports to guide classroom assessment and lesson planning.
