The present thesis entitled School managers and administration and evaluation systems in Minas Gerais: a proposal for a model of analysis of data use sought to understand the different articulations between organizational factors and educational actors before the process of pedagogical data use in the management of data. schools. To this end, initially, we performed a bibliographic review in which we mapped seven factors that influence the process of pedagogical use of data, namely: the organizational context, management systems, support and access to technology, training for the use of educational data , the director s rationality, the school climate and the director s leadership. Therefore, in each of the chapters of this thesis we theoretically discuss each of these factors combined with the empirical data of the case studies carried out in two state schools in Minas Gerais under the jurisdiction of the Regional Teaching Superintendence of Juiz de Fora (MG). After the analysis processes developed during the research and from the experience of the researcher in schools, we present in the final chapter of the thesis a new factor to be added as a potential influencer in the use of data for pedagogical purposes in the school: trust in the data. This is because the fact that the educational managers trust or not the data of the administration and evaluation systems makes the educational data to be used pedagogically in the school. As a final result of this thesis, we present a proposal for a model of analysis of the use of data.
