The purpose of this study is to understand the qualitatively different ways that current practicing teachers are using data to inform instruction. Nine elementary schools teachers participated in this study. Findings from teacher interviews are presented through the image of a ladder representing the stages that teachers experience as they engage in data usage to inform their instructional decision making. These findings have implications for teacher educators and school-based practitioners alike in better supporting the professional development of preservice and in-service teachers for this data-driven context of schools.
