This tool was designed to deepen the understanding of what it takes to develop a system of excellent high schools. It provides a framework and guidelines for district leaders, community stakeholders, educators, administrators, parents and students to discuss, assess and map out the process of transforming their high schools to meet the needs of all students. School districts and community partners that have just begun or are in the midst of a systemic high school transformation agenda can use this tool to guide their reform process. The tool is divided into three separate conversations: (1) "Setting Up the Process: Determining Where Your District/Community Is in Developing and Implementing a High School Transformation Agenda" provides a framework and initiates a process to help districts, schools and communities gauge where they are in developing and implementing a systemic vision for high school transformation; (2) "Collecting Evidence: Assessing Development and Implementation" provides a process for collecting and assessing evidence and identifying barriers and opportunities in each of the core elements of the systemic change framework; and (3) 'Analyzing Progress and Developing Priorities and an Action Agenda" supports key stakeholders as they analyze their stage of development in systemic high school transformation and develop priorities or an action agenda for deepening or moving the work forward. Each section contains an overview, worksheets and readings. Three appendixes are included: The Systemic Change Framework for High School Transformation; and worksheet templates for Parts 2 and 3A. (Contains 10 footnotes and 3 figures.)
