An experience of university-school linkage is presented in a community composed of female teachers of early childhood education and university female professors who develop a cycle of collaborative inquiry aimed at improving teaching practices. The sessions were recorded and analyzed qualitatively and show how the community transits through the phases of 1) identification of common goals; 2) inquiry and action; and 3) analysis and joint reflection oriented towards improvement. As opportunities of this strategy emerge the development of a collegiate dialogue, relationships of professional trust, reflection on the practice, and assessment of different expertise; and as challenges, time allocation and securing medium- and long-term support from both institutions. For future initiatives, it is suggested to agree on the conditions of participation of the actors and the institutional support required, so that teachers and academics can actively participate in the investigation process.
