This dissertation study explores the perceptions of principals as literacy leaders and the enactment of these perceptions in high-need elementary schools. Literacy leadership, as perceived by principals, was analyzed based on interview data from six participants. Individual cases were studied for the unique characterizations each participant brought to the construct of literacy leadership through their own lived experience. Cross-case analysis was conducted in order to draw out themes among participants. Conclusions suggest that there are commonalities among principals' perceptions and enactments as literacy leaders in high-need elementary schools. Participants focused on: adoption of literacy programs and curricular fidelity; data use for reflective practice; building cultures of high expectations; distributed leadership models for improved literacy instruction; and professional development to support language arts instruction. Particular aspects of literacy leadership, such as literacy engagement and family-literacy school connections, were not as great a focus in participant interviews.
