This article describes the implementation of the Collaborative Inquiry Network (CIN) methodology. Specifically, it describes the work carried out by school directors from two different networks within a given commune, with a total of 21 basic education establishments. Collaborative inquiry was conducted through a cyclical three-phase process: identification of shared challenges; inquiry and action; reflection and monitoring. Through content analysis, we studied a series of collaborative inquiry projects developed by several educational teams. The results reveal that networking has allowed the development of the leadership skills, professional learning and data analysis necessary for the development of learning communities. Furthermore, those projects that involve common actions among different establishments aimed at innovation and school improvement are of great value to the participants.
