The Carlisle Area School District has been a leader in the provision of virtual learning opportunities to students beginning with the submission of the Digital School District grant application in December 7, 2000. The CASD was one of three districts chosen as a recipient of this large monetary grant to simulate a (technology-related) model of high schools of the future in the state of Pennsylvania which required a shift to a web-based or Internet-driven system. This shift among other things allowed for an expansion in the ways curriculum and instruction could be provided to students and hence, virtual course offerings progressively became a viable component of the existing educational program.

Since 2000 Carlisle High School has offered students the opportunity to take elective enrichment courses online. Years later CHS joined other area high schools who also offered online courses under the moniker of the Pennsylvania Virtual Academy Coalition (PVAC) to expand these offerings whereby students could enroll in virtual courses offered by any of the member schools. In 2008 Harrisburg Area Community College joined the PVAC umbrella which provided some additional enrichment types of courses available to students attending any of the high schools in the PVAC consortium. Still the catalog of offerings was limited and targeted only enrichment (as opposed to remedial or make-up) types of courses.

In 2009, Carlisle and three other schools districts chose to form their own consortium (South Central Cyber Consortiumà SC3) using K12 Learning as the provider of online curriculum and instruction for students in each of their respective districts. Carlisle High School is currently transitioning to a system that will allow our own district teachers to deliver the instruction with customized content.
