The study includes an elementary, middle, and high school principal along with two teachers from each school who worked at schools that were in good standing from 2007-2011. Each school made adequate yearly progress (AYP) each year according to the "No Child Left Behind Status History Report." This study examined one over arching research question: What do principals and teachers say about school and schooling? Data for this study was gathered through principal interviews, teacher interviews, and the results of an online Inventory of Leadership Styles (ILS) self-report and direct-report survey. The findings and actions by the principals in this study revealed that principals' leadership styles have an indirect effect on teacher and student performance. The leaders in this study set clear goals and directions built around high academic expectations. They worked to build faculty morale by empowering and motivating teachers.
