Abstract

This study explores how school environments and principal behaviors enhance the use of data within Chile’s high-stakes accountability systems. Emphasizing the importance of Data-Driven Decision Making (DDDM) for improving educational outcomes, this mixed-methods research analyzed data employment for accountability, improvement, and instructional purposes. Findings show that schools prioritize data use for enhancing in- struction and school improvement over mere compliance with external accountability. Key leadership behaviors, notably instructional leadership, are crucial in promoting effective data utilization. The study identifies both minimal and organizational conditions as critical enablers for data use, although their impact varies with the type of data employed. The results advocate for a balanced approach that considers both quantitative and qualitative factors to optimize data use in educational settings. Future research should delve deeper into specific instructional practices and the factors that influence teacher decision-making to further improve data-driven instruction.
