Findings of a study that examined principals' leadership behaviors in implementing a systemic program for school reform and improvement are presented in this paper. The program, Reaching Success through Involvement (RSI), is an implementation strategy that involves comprehensive assessment and student leader participation. A survey was administered to 1,426 teachers from 30 schools participating in RSI to determine views of their principals' leadership. Findings confirmed the importance of the three factors of effective leadership that were identified in the literature: developing and maintaining structure, providing consideration, and developing an organizational culture. A new construct was also identified--personal challenge--which is the ability to empower others by creating opportunities for personal or professional growth. A conclusion is that administrators need to play a more active role in helping school community members find job satisfaction and meaning. Nine tables are included. The appendix contains a copy of the survey instrument. (Contains 53 references.) (LMI)
