The creation and implementation of innovation proposals in education can provide a new key towards sustainable development. We are aware that schools perform very different innovations but often, with very low levels of impact and dissemination in their community. There are not many studies that describe, put a value on, categorize or analyse the innovations. This study sought to gain insight into the ICT innovations produced in Spanish primary and pre-primary schools. A quantitative approach based on a questionnaire was used to collect the data, named MANEDUIN, completed by 86 teachers selected by stratified random sampling (public - private, rural - urban). The reliability and the construct-related validity was evaluated from the questionnaire and the validity of content decided by means of experts’ judgment. Our findings point to a good consistency in the questionnaire (Cronbach’s Alpha: 0.848). The descriptive statistics and the analysis were made by factorial categories. The results of the factorial analysis confirm the dimensions proposed in the design of the questionnaire in the categories of the factors included in the innovation (social cohesion, interaction with the community, technologies, and success), the innovative schools and their characteristics, the topic and the type of innovation (on resources, direction, materials and time), as well as the obstacles to the innovation. This paper concludes that the questionnaire MANEDUIN is a valid and reliable tool to measure the management of schools’ innovations.
