Kaestner is the TCO (total cost of ownership) project director for the Consortium for School Networking (CoSN), a national nonprofit group that helps K-12 schools effectively use technology to improve both teaching and learning. CoSN, in tandem with Gartner, a research and advisory firm, has developed a free, vendorneutral, online tool--in the words of its website, "to help schools and school districts make sound budgetary decisions, conduct technology planning in an organized way, establish a baseline for future analysis, and maximize benefits from their investments in technology." In this article, the author discusses the new online TCO tool and the advantages of using it. The TCO tool provides districts an easy, efficient way of analyzing their resources and gaining support for those solutions. Regardless of the visible advantages of using the TCO tool CoSN's Kaestner says it is the larger benefits that provide the bottom line: "You're not installing technology to save money; you're doing it to enhance students' education."
