South County Secondary School incorporates instructional technology in creative and effective ways to further the academic mission of the school. Technology is used to facilitate student learning and to develop skills critical to information and technical fluency in the 21st Century. Staff members use the extensive technology tools at South County to engage and challenge students, as well as to bring efficiency to the management and assessment of learning.

The school operates a building-wide local area network (LAN) that allows students to access a high-speed Ethernet network. A component of this LAN is a high-speed wireless network, enabling computers and other wireless devices to connect at speeds up to 54Mbps. Each student and staff member has an individual account on this network, including the capability to store files and access resources on school servers. The South County LAN connects to the Fairfax County Public Schools wide area network (WAN). As per federal and state regulations, Internet access is filtered to deny access to websites deemed inappropriate for juveniles by the Code of Virginia.

There are over 1900 high-end computers at South County. This includes approximately 1000 laptop computers, more than 900 desktop computers, and 9 servers.

Large interactive whiteboards, or “SmartBoards,” are a vital part of the instructional technology at South County Secondary School. With this technology, students and teachers can easily interact with the computer, using their fingers as the mouse while the class follows by watching the large screen. They can write with digital ink over anything and save their notes to a single file that can be distributed and shared with ease. Every teaching area in the building is equipped with an interactive whiteboard, a data projector, a high-speed laser printer, a DVD/VHS player, stereo speakers, and at least one computer.
