This checklist is designed to help states at various stages develop their system of support to reach struggling high schools. The checklist can be used to assess where your state is in terms of the elements of using existing support and guidance mechanisms, and reconfiguring and/or creating new structures to leverage system change for high school improvement. The elements listed in the checklist may be helpful in establishing or refining your state's education planning and implementation process. The checklist covers curriculum and instruction; assessment and accountability; teacher quality and professional development; resources, financial, and other; leadership and governance; organization and restructuring; student supports and interventions; and additional contextual factors. A list of key federal funding streams affecting high schools is included. [This checklist was prepared by the National High School Center.]
