Sevenoaks School's campus is fully networked to allow users across all buildings to share resources, giving staff and students access to a wealth of on-line materials and network facilities. With around 800 PCs and portable devices in use from boarding houses to classrooms, pupils nearly always have access to a computer. Wireless Local Area Networks (LANs) installed strategically around the school provide the right speed of access at the right time to the right people.

Technology is integrated into teaching and learning. Departments across the curriculum use computing suites innovatively and excitingly, with subject-specific software and tools from tablets, voting devices, interactive whiteboards and scientific equipment to digital cameras and recording equipment. All teaching spaces are equipped with a data projector or screen. The Firefly learning platform is accessible online from any device or operating system with access to the internet.

The Computing Department has three computer suites where the latest technologies are used to teach lessons in IT and other subjects. Students are encouraged to develop skills and knowledge in IT and computing that they can use across the curriculum. The emphasis in the Computing Department is on open learning by exploration and personal involvement.

Each boarding house has a suite of PCs for pupil use; students can also access the wireless network from their laptops and other mobile devices. The IT Service Department contributes to the school's aim to minimise the consumption of electrical and fossil fuel energy whilst providing ever-better facilities through environmentally aware procurement, ethical disposal, technical solutions and user awareness training.
