Abstract
How does the governance of the school system operate on the territory ? This thesis is based on the trajectory of a school sectorization system in order to understand the change in local public action. Based on an in-depth empirical investigation and a multi-level strategic analysis, I reveal the complexity of the network of actors and the entanglement of competences around the school system in the local political-administrative organization. This instrumental and experimental approach opens up analytical perspectives situated at the intersection of heterogeneous issues (academic, political, social, urban, security, etc.) that have come to refract in the trajectory of the device.
