This study explored principle licensure students' sense of engagement, program effectiveness, and preparedness to lead engagement focused on academic achievement. Data analysis using attributes of effective preparation programs, and positive psychology constructs (e.g., flow) found "Goal Achievement," "Commitment," and "Accomplishment" significantly related to flow. "Flow" was significantly related to "Engagement," while "Care" was significantly related to "Commitment" and "Coping." Perhaps more significantly, the findings yielded seven characteristics of Engaged School Leadership Theory (ESTL) development. Adding to both principal preparation and positive psychology literature, this study offers conceptual understandings toward an emerging theory of Engaged School Leadership.
