The purpose of this qualitative, single case study was to identify leadership practices and processes that contributed to the success of a single High Needs, Title 1 elementary school that has experienced acknowledged superior academic success, particularly for its minoritized and low socioeconomically disadvantaged students, as indicated by the school's success on the State of Texas Assessment of Academic Readiness (STAAR) tests. The study sought to explore the principal's and teachers' conception of leadership for success and to examine what effective practices and processes were employed at a high-needs, high-performing campus that accounted for its success. The study applied the culturally responsive school leadership (CRSL) framework to analyze the practices employed at the school. Results of the study, from interviews with the principal and a focus group of three teachers, indicated that not only did they apply the principles of the CRSL framework, which employed the critical self awareness, culturally responsive curricula and teacher preparation in a culturally responsive and inclusive school environment which engaged parents and students in community contexts, but they also enhanced their effectiveness through the provision of additional resources for teachers and students, with a heavy reliance on data to guide academic decisions.
