This document outlines the bases for implementing a "Digital Backpack Plan" in schools in Castilla-La Mancha, Spain. The plan aims to transition schools from traditional textbooks to digital educational resources. It will be implemented in a maximum of 100 schools over the 2014-2015 school year. Schools must meet infrastructure and other requirements to participate. A selection committee will evaluate applications based on criteria such as the school's experience with technology, available devices, and measures planned to engage families.
