The purpose of this study was to gain insight about high school principals who are considered effective by organizations and institutions in the state of Indiana. Through a qualitative study, five Indiana high school principals participated in an interview with 26 structured questions. The participants were selected based on recommendations from major Indiana universities granting administrative licensure and the Indiana Association of School Principals. The participants could serve in rural, urban, or suburban districts in Indiana. Gender, race, or ethnic differences were not considered. State and federal test results were not a deciding factor for selection. There were five conclusions as a result of this study: 1. The preparation program establishes a solid base for aspiring principals regardless of program or internship. In addition, new principals benefit from an informal mentor. 2. Increased accountability is seen as a positive rather than a negative by effective principals. 3. Effective Indiana high school principals adapt their leadership skills to meet the demands necessary to lead successful schools. 4. Effective Indiana high school principals are optimistic people. 5. Stress is an accepted part of the job for Indiana high school principals. [The dissertation citations contained here are published with the permission of ProQuest LLC.
