The purpose of this quantitative study was to investigate the relationships among the dimensions of resilience and the individual demographics of high school principals toward strengthening the leadership abilities of school principals. The study employs the survey method in its research design. Those surveyed included 68 high school principals, from 6 school districts in the State of Florida. The investigation used an on-line questionnaire to collect data on the dimensions of resilience and demographics of these principals. The data were analyzed by using the Independent Sample T-test. Hypothesis testing was introduced to determine statistical significance. The statistical significance level was set at p (probability) < 0.05. The investigation found significant relationships among the resilience dimensions of Positive, Flexible, Organized, Focused and Organized, and the individual demographics of these school principals. The application of the dimensions of resilience can be utilized as a powerful competitive advantage for any educational institution facing major changes. Principals who accept the resilience model reflect greater change adaptability. Resilient principals who manage change successfully not only improve their school's performance but also become more effective leaders. To achieve lasting change, though, they must stay sensitive to the external realities, in this global environment, and encourage faculty, staff and students to be open-minded to the world outside and the boundaries of the school. Therefore, school principals should be ahead of change and not behind it trying to catch up (Kouzes and Posner, 2002).
