The purpose of this study was to compare the perceptions of self-reported leadership practices using the Kouzes and Posner Leadership Practices Inventory between high school principals in North Carolina who were coaches with those principals who were not coaches. This quantitative study was conducted using a survey-design method in which all 368 public high school principals in North Carolina were given the opportunity to participate. A Principal Demographic sheet along with the 2003 edition of Kouzes and Posner's Leadership Practices Inventory (LPI) Self- Form was used to gather information regarding the principals' perceptions of their leadership practices. The response rate was 64.9%. This study determined that for the research question: Do the Kouzes and Posner mean scores (for the five dimensions) differ between principals who have been coaches and those who have not, no significant difference, as measured by η2 (< .01) was reported in any of the five dimensions. This study established that North Carolina high school principals reported significantly higher levels on each of the 5 leadership practices than did those individuals in the Kouzes and Posner study. In addition, a positive relationship was found between the number of previous years of coaching experience and 3 of the 5 leadership practices. The study determined that there was little difference in the mean scores between male and female North Carolina principals.
