Central Valley IT Resources Group Welcome! The Central Valley IT Resources Group is a listserv dedicated to helping educational IT professionals. Our Purpose: to enable LEAs in California’s Central Valley to share information on vendor contacts, site visits, and any technology-based information that is helpful to the whole. This list will not be used by vendors to solicit business, but is aimed at giving LEAs along the 99 corridor a platform to share vendor contact information, and their opinions and experiences of those vendors.
