The school is inserted as a component of the current society of organizations, being one of the components of the macro organizational system, which suggests the need for good management so that it remains sustainable and competitive. Thus, this study aims to suggest the PDCA cycle as a proposal for efficient school management. For this, the conceptual bibliographic method developed by Nascimento-e-Silva (2012) was used, which consists of the formulation of guiding questions, data collection in scientific books and databases, organization and interpretation of data for the generation of responses. The results obtained showed that the PDCA Cycle is a tool that contributes to the efficiency of school management, because it provides a framework for the application of methods of continuous improvement based on the theory of managerial knowledge that can be used in the most diverse realities and educational institutions. Key-word: PCDA; school management; administration.
