Computing at School (CAS) is dedicated to revolutionising computing education
We are a community of professional practice that forms a nationwide network of computing educators powered by BCS, The Chartered Institute for IT. Find out more about how CAS’s connection with BCS helps us achieve our mission here.
At the heart of CAS is a vibrant community of volunteers – teachers, technologists, and advocates – whose passion and generosity continue to inspire. Together we work to ensure that every teacher has the skills and confidence to deliver engaging, inclusive, and effective computing lessons so that every child leaves school equipped to participate in and contribute to a healthy digital society.
Our impact



With the support of BCS and other partners, CAS has worked tirelessly to re-envision computing education. Our success has seen us instrumental in:
- Influencing policy
Established computing education as an entitlement for every child, building the business case for government investment in continuing professional development (CPD) for teachers. - Supporting teachers
Provided over 141,000 teachers across all age groups with access to CPD and resources. - Improving opportunities
Helped to drive a 370% increase in computing GCSE entries since 2014. - Growing learner participation
The schools supported by CAS enter 18% more candidates for GCSE Computer Science. That’s an extra 7,000 young people each year who are better equipped for our digital world. - Improving outcomes
Young people in secondary schools that are supported by CAS achieve a GCSE Computer Science grade that is on average 0.2 higher than those at other schools. That’s the equivalent of a year’s extra progress.
