In different states of the Mexican Republic there are collective educational projects that, to a greater or lesser extent, are set up in public school classrooms at the basic level, promoting community involvement, work based on collectivity and the promotion of active participation by educational subjects. The political and epistemic meaning of local educational projects that go against the grain of official national education is accompanied by the projects pursued by the people and teachers' groups, through the construction of their own knowledge and experiences from which they deploy strategies for the social appropriation of the school. These school alternatives form an emerging scenario of collective action where diverse expressions of the National Coordinator of Education Workers synthesize their political-educational projects. This article proposes to review, from an ethnographic methodology, the interactions in the school environment, how these initiatives are implemented in the educational territory and what are the main challenges in the complex task of resisting the conventional model of the state school in order to put it at the service of the teachers' and popular struggles. The findings of these experiences of alternative education constitute significant inputs for rethinking the way in which different social actors recover the school space to feed their own projects of society and socio-political transformation that they raise from their praxis in the educational field.
