INTRODUCTION. Educational innovation is experiencing in Catalonia (Spain) what has begun to be called a "third pedagogical spring" that is leading to a significant increase in schools that make changes at different levels. METHOD. In this context, taking as a reference classifications of types of educational innovation (innovations in the formative structure, pedagogical, process, teacher training and the educational chain), the article presents the analysis of questionnaire carried out on the whole of the population (N) of non-university educational centers of the Territorial Education Service of Lleida (Catalonia). The intention of the questionnaire, and of the research project, was to detect: the degree of innovation of the non-university educational centers as a whole (differentiating the different educational levels), the degree to which this innovation is sustainable over time, the reasons that lead to innovation and its degree of success. In summary, the RESULTS indicate that there really is an "innovative spring" (although some levels of education are higher than others) that can be generalized, as other studies indicate, to the whole of Catalonia. This spring focuses mainly on the implementation of pedagogical actions, formative structure and with the educational chain and is motivated by the interest of improving results, motivation, learning... of students. Although entering into DISCUSSION with other studies also responds to pressure from society and families for educational change.
