Computer Science


At Heathfield we believe that computing skills are essential for success in other subjects, in higher education and are one of the fundamental transferable skills required by employers. computing at Heathfield provides an exciting curriculum that delivers essential skills based on real life scenarios that effectively engages and inspires students, of every ability, to achieve great things.

“ICT in education is the key to unlocking the skills and knowledge of our future generations of young people. It is the tool for learning for the 21st century."
Kate McKenzie

At KS4 we offer both a Computer Science and Information Technology option. This allows our students to begin their digital journey with specific skills for the destination they are aiming for.

OCR GCSE Computer Science [J276] (Specification)

Note: J276 Currently being taught in year 10 & year 11. From September 2020 we will be delivering “OCR GCSE Computer Science [J277]" (Specification)

OCR’s GCSE (9–1) in Computer Science will encourage learners to:

  • understand and apply the fundamental principles and concepts of Computer Science, including abstraction, decomposition, logic, algorithms, and data representation
  • analyse problems in computational terms through practical experience of solving such problems, including designing, writing and debugging programs
  • think creatively, innovatively, analytically, logically and critically
  • understand the components that make up digital systems, and how they communicate with one another and with other systems
  • understand the impacts of digital technology to the individual and to wider society
  • apply mathematical skills relevant to Computer Science.
