Computer Science – Key Stage 4
Pearson Edexcel GCSE (9-1) in Computer Science
Students are able to choose Computer Science as an option subject in Year 10 and 11, following the Edexcel 2016 specification GCSE qualification. The Edexcel GCSE Computer Science counts as a science option in the EBacc measure in secondary school performance tables. This means that a student who sits any three of the four separate sciences (Biology, Chemistry, Physics and Computer Science) and achieves a C or above in two of them will fulfil the science requirement of the EBacc.
There’s more to Computer Science than simply programming. Computer Science is the study of how computer systems work, how they are constructed and programmed. It consists of a body of knowledge, a set of techniques/methods for solving problems, as well as practical programming skills. What this means is that a course in Computer Science has to cover a lot of theory teaching, as well as plenty of practical problem solving and programming. Computational thinking is a large part of the course and forms the bulk of what is taught.
This qualification specifically aims to:
The Pearson Edexcel GCSE (9-1) in Computer Science consists of two externally-examined papers and a non-examined assessment component.
Students must complete the non-examined component in March and all external assessments in May/June in any single year.
