Federal and state guidelines for school reform dominate the landscape of public education. Florida and its school districts, as a Race to the Top state, are in the process of fully implementing a value-added model of teacher evaluation. Effective school leaders are calling upon the theoretical framework of transformational, visionary and distributive leadership practices to manage the change process and align the mandate with a school's vision and mission. The research study examined the leadership theory and practices of a high school leadership team as Marzano's teacher evaluation system was implemented. The use of the Multifactor Leadership Questionnaire developed by Bass and Avolio identified strengths and weaknesses as reported by a leadership team consisting of a principal, assistant principals, and department chairs.
