This study examines administrator perceptions of Pennsylvania's state assessment data. This study had three main purposes. The first purpose was to investigate the value and utility of state assessment data to inform decision making and the possibility of improving student achievement through the routine use of state assessment data. The second purpose of this study was to understand to what extent and how administrators use state assessment data to inform decisions. The third purpose was to explore what factors influence administrators' use of state assessment data. The researcher sought to identify current data analysis practices, define strengths, describe opportunities for growth, and make recommendations for ongoing improvement. The need for this research is evident as federal and state accountability mandates have changed since the Every Student Succeeds Act was passed in 2015. Accordingly, this study provides insight for school district leaders who are seeking opportunities to develop and sustain a routine and systematic approach to analyzing and utilizing state assessment data to address student learning outcomes.
