The Consortium for School Networking (CoSN) has announced the availability of a new online tool to help school leaders calculate the total cost of ownership (TCO) of their technology investments. This free, vendor-neutral resource was developed for CoSN by Gartner Inc., a leading research and advisory firm that helps businesses understand technology, with funding from the U.S. Department of Education. Visitors who click through to the tool’s web site can review an article entitled “Learn Why Total Cost of Ownership Matters” and read case studies that Gartner prepared after working with four school districts of varying sizes across the country. After registering on the site, users also can calculate their own estimated TCO by inputting data about their school technology programs. The tool is most useful as a benchmark for school leaders to assess the current costs of managing their technology and how these costs might change in the future. eMail support is available for those with questions about using the tool.
