Behind the challenges listed here is also a pervasive sense that local and organizational constraints are likely the most important factors in any decision to adopt — or not to adopt — a given technology. Even K-12 institutions that are eager to adopt new technologies may be constrained by school policies, the lack of necessary human resources, and the financial wherewithal to realize their ideas. Still others are located within buildings that simply were not designed to provide the radio frequency transparency that wireless technologies require, and thus find themselves shut out of many potential technology options. While acknowledging that local barriers to technology adoptions are many and significant, the advisory board focused its discussions on challenges that are common to the K-12 community as a whole. The highest ranked challenges they identified are listed here, in the order in which the advisory board ranked them.
